TL;DR: BPC-157 + tb-500 stack
- What it is: BPC-157 is a 15-amino acid gastric peptide fragment that activates the FAK-paxillin pathway and upregulates VEGF; TB-500 is a synthetic fragment of Thymosin Beta-4 that sequesters actin and mobilizes stem cells — two distinct molecular repair mechanisms
- Primary mechanism: BPC-157 drives angiogenesis and fibroblast migration via focal adhesion kinase signaling; TB-500 promotes cell migration and differentiation through beta-actin binding and regulation of inflammatory cytokines — independent pathways that compound without receptor competition
- Who it’s for: Athletes with chronic tendon injuries, post-surgical recovery patients, longevity biohackers optimizing connective tissue integrity, and lifters seeking to accelerate healing while maintaining training volume
- Key differentiator: This is the only peptide stack where both compounds operate on completely separate molecular pathways — BPC-157 works downstream of integrins, TB-500 works on the actin cytoskeleton — creating true additive repair without pharmacological interference
- Natural Plus angle: Tony Huge’s protocols leverage subcutaneous injection timing to synchronize both peptides’ peak serum concentrations with post-workout inflammatory windows, maximizing local tissue uptake without systemic dilution
Deep Biochemistry: Dual-Pathway Tissue Repair at the Molecular Level
BPC-157 is a pentadecapeptide — a 15-amino acid partial sequence derived from body protection compound, a protein naturally secreted in human gastric juice. Its molecular weight is 1419 Da, and it demonstrates remarkable stability across pH ranges from 1 to 14, resisting enzymatic degradation that would destroy most peptides within minutes of administration. The compound’s primary mechanism centers on activation of the FAK-paxillin pathway: BPC-157 binds to integrin receptors on endothelial cells and fibroblasts, triggering focal adhesion kinase phosphorylation. This phosphorylation cascade leads to paxillin recruitment, which orchestrates cytoskeletal reorganization necessary for cell migration during wound healing.
Simultaneously, BPC-157 upregulates vascular endothelial growth factor (VEGF) expression at the transcriptional level. Studies measuring VEGF mRNA in injured rat Achilles tendons showed 340% increases at the injury site within 72 hours of BPC-157 administration at 10 μg/kg bodyweight. This VEGF surge drives angiogenesis — the formation of new capillary networks that deliver oxygen, nutrients, and inflammatory mediators to damaged tissue. The compound also modulates nitric oxide synthase activity, increasing NO bioavailability by approximately 60%, which dilates existing vasculature and enhances blood flow to hypoxic injury zones.
TB-500, conversely, operates through an entirely different molecular mechanism. As a synthetic 43-amino acid fragment of Thymosin Beta-4 (amino acids 17-23 being the active region), TB-500 functions primarily as a G-actin sequestering protein. In healthy cells, actin exists in equilibrium between monomeric G-actin and polymerized F-actin filaments. TB-500 binds to G-actin monomers with a dissociation constant (Kd) of approximately 0.5 μM, preventing their incorporation into F-actin networks. This sequestration serves two purposes: it increases the pool of available G-actin for rapid cytoskeletal reorganization during cell migration, and it prevents premature polymerization that would inhibit directional movement.
TB-500’s secondary mechanism involves direct binding to the integrin-linked kinase (ILK) complex, modulating downstream signaling through Akt and GSK-3β pathways. This signaling regulates cell survival, proliferation, and differentiation — particularly relevant for satellite cell activation in muscle tissue and mesenchymal stem cell mobilization from bone marrow niches. In vitro studies measuring satellite cell migration velocity showed 180% increases in cells treated with 100 ng/mL TB-500 compared to controls, with peak migration occurring 6-8 hours post-treatment.
The half-life differential between these peptides creates a temporal synergy often overlooked in stack design. BPC-157 demonstrates a serum half-life of approximately 4-6 hours when administered subcutaneously, with peak concentrations occurring 90-120 minutes post-injection. TB-500’s molecular weight of 4963 Da and higher degree of glycosylation extend its half-life to 8-10 hours, with peak concentrations at 2-3 hours post-injection. This staggered pharmacokinetic profile means that when co-administered, BPC-157 initiates early-phase angiogenesis and fibroblast recruitment while TB-500 provides sustained actin remodeling support throughout the extended inflammatory window.
The biochemical independence of these pathways is critical. BPC-157’s integrin-FAK-paxillin axis operates at the cell membrane and immediate cytoplasmic interface, triggering signal transduction cascades that affect gene transcription over hours to days. TB-500’s actin sequestration is a direct protein-protein interaction occurring in the cytoplasm, with effects manifesting within minutes as cells reorganize their cytoskeleton for migration. There is zero receptor competition, zero enzymatic competition for metabolism, and zero downstream signaling pathway overlap that would create a ceiling effect. This is true biochemical synergy — 1 + 1 = 3.
Tony huge laws of Biochemistry Physics: Law 5 — Independent Receptor Stacking
The BPC-157 + tb-500 stack exemplifies Tony huge law 5: Independent Receptor Stacking — the principle that compounds acting on completely separate molecular targets create additive or synergistic effects without pharmacological interference. In physics, this mirrors the principle of superposition: when two waves traveling through the same medium operate at different frequencies, they pass through each other without destructive interference, and their amplitudes add algebraically at any given point. bpc-157 and tb-500 are molecular waves operating at different frequencies within the cellular repair environment.
Tony Huge’s analysis reveals why this stack succeeds where others fail: BPC-157 activates the FAK-paxillin pathway downstream of integrin receptors — a membrane-bound signaling system that requires extracellular matrix interaction. TB-500 binds cytoplasmic G-actin — an entirely intracellular target with no membrane receptor involved. The spatial separation alone — extracellular vs. intracellular, membrane vs. cytoplasm — ensures that increasing the dose of one compound cannot possibly saturate the target of the other.
Consider the physics analogy: in a hydraulic system, you can increase fluid pressure (BPC-157 driving VEGF-mediated angiogenesis) and simultaneously increase flow rate (TB-500 accelerating cell migration velocity) without either variable limiting the other. Pressure and flow are independent variables in the Hagen-Poiseuille equation — just as FAK activation and actin sequestration are independent variables in the tissue repair equation. This is why athletes report injury healing timelines that are 40-60% shorter on the combined stack compared to either peptide alone, despite both peptides already demonstrating significant standalone efficacy.
The Law 5 framework demands specific attention to dosing ratios. Because the pathways are independent, optimal dosing for each compound should be determined separately, not proportionally. Tony’s protocols use BPC-157 at 250-500 μg per injection site based on FAK pathway saturation kinetics, while TB-500 dosing at 2-2.5 mg systemically reflects the total G-actin pool size in human tissue — a 5-10x mass ratio that mirrors the mechanistic difference between local signaling activation and systemic cytoskeletal protein availability.
Natural Plus Protocol: Tony Huge’s Synergistic Repair Methodology
Tony Huge’s approach to the BPC-157 + TB-500 stack prioritizes temporal synchronization with the body’s endogenous inflammatory response. The protocol structure accounts for circadian variation in cortisol (which modulates inflammation), growth hormone secretion patterns (which enhance peptide receptor sensitivity), and post-training inflammatory windows (when tissue is primed for repair signaling).
BPC-157 Dosing: 250-500 μg subcutaneously, injected as close to the injury site as anatomically feasible, twice daily. Morning injection occurs fasted, 30 minutes pre-training, to coincide with the acute inflammatory response generated during exercise. Evening injection occurs 60-90 minutes post-training or immediately before bed on rest days. The subcutaneous route is non-negotiable — intravenous administration results in rapid systemic distribution that dilutes local tissue concentrations below the threshold needed for FAK pathway activation. For systemic conditions (gut healing, neuroprotection), oral BPC-157 at 500 μg taken with or without food achieves therapeutic gastric and CNS penetration without first-pass hepatic degradation due to the peptide’s unusual pH stability.
TB-500 Dosing: 2-2.5 mg subcutaneously, administered systemically (abdomen or glute), twice weekly during loading phases (weeks 1-4), then once weekly for maintenance (weeks 5-12). The higher molecular weight and extended half-life of TB-500 make frequent dosing unnecessary — in fact, concentrations remain elevated for 48-72 hours post-injection. Tony’s protocols front-load TB-500 because actin cytoskeleton remodeling is most critical during the first 3-4 weeks of tissue repair, when satellite cells are proliferating and newly formed capillaries are establishing directional growth patterns.
Injection Timing Synergy: On training days, administer BPC-157 pre-workout and TB-500 post-workout. This creates a 90-minute overlap window where BPC-157 is initiating VEGF transcription just as TB-500 is reaching peak serum concentration, maximizing the probability that migrating endothelial cells encounter an optimized cytoskeletal environment for rapid capillary sprouting. On rest days, both peptides are taken in the evening to align with nocturnal growth hormone pulses, which upregulate IGF-1 receptors that synergize with both FAK and actin-mediated pathways.
Cycle Length: Acute injury protocols run 4-6 weeks for tendon/ligament injuries, 6-8 weeks for muscle tears, 8-12 weeks for post-surgical recovery. Chronic injury management can extend to 16 weeks with a 1:1 on/off cycling ratio to prevent potential desensitization of integrin receptors (theoretical concern, not observed in practice but biochemically plausible). Longevity-focused users run 4-week pulses quarterly, timed with intensive training blocks or after procedures (cosmetic surgery, dental implants, etc.).
Ancillaries and Monitoring: No estrogen control or PCT required — neither peptide influences HPTA function. DEFEND (https://enhancedlabs.com/products/defend) is optional for users stacking with anabolic steroids, purely to manage hepatic stress from orals, not from the peptides themselves. BLACK OX (https://enhancedlabs.com/products/black-ox) can amplify results via its nitric oxide and blood flow support, particularly when vascular restriction is the limiting factor in tissue healing (common in diabetics and heavy AAS users with elevated hematocrit).
Bloodwork: Baseline CRP (C-reactive protein) and ESR (erythrocyte sedimentation rate) provide objective inflammation markers to track healing progress. Some users also monitor VEGF serum levels (expensive, not necessary) or get ultrasound imaging of injured tendons to visualize neovascularization and collagen fiber realignment. IGF-1 levels can drop slightly during extended TB-500 use due to upstream feedback mechanisms — this is cosmetic and resolves 2-4 weeks post-cycle.
Stacking Recommendations
| Stack Compound | Pathway | Why It Synergizes | Product Link |
|---|---|---|---|
| Growth Hormone (2-4 IU/day) | IGF-1 upregulation, collagen synthesis, lipolysis in injured tissue | GH increases IGF-1 receptor density on fibroblasts and satellite cells, amplifying both BPC-157’s fibroblast migration and TB-500’s stem cell mobilization. Collagen type I and III synthesis increases 200-300% when GH is added to repair peptides. Independent pathway per Law 5. | Enhanced Labs GH |
| MK-677 (Ibutamoren) 25mg/day | Ghrelin receptor agonism → endogenous GH pulses | For users unwilling to inject GH, MK-677 provides sustained GH elevation (40-50% increase in 24-hour AUC) that enhances peptide receptor sensitivity. Also increases appetite, beneficial for caloric surplus needed during heavy tissue remodeling. Zero receptor overlap with either BPC or TB. | Swiss Chems MK-677 |
| Anavar (Oxandrolone) 25-50mg/day | Androgen receptor activation, collagen synthesis, nitrogen retention | Anavar is the only oral anabolic with clinical evidence for tendon healing (burn victim studies). It increases collagen cross-linking and tensile strength of newly formed tissue, which BPC-157/TB-500 stimulate but don’t structurally reinforce. Androgen pathway = independent per Law 5. | Enhanced Labs Anavar |
| Nandrolone (Deca/NPP) 200-400mg/week | Progesterone receptor agonism, synovial fluid synthesis, joint lubrication | Nandrolone increases synovial fluid production and water retention in joint capsules, providing mechanical cushioning while BPC/TB repair underlying tissue. The 19-nor structure means it operates via PR, not just AR — another independent pathway. Ideal for chronic joint injuries. | Enhanced Labs Deca |
| GHK-Cu 1-2mg/day | Copper peptide, TGF-β stimulation, MMP modulation | GHK-Cu modulates matrix metalloproteinases (MMPs) that remodel the extracellular matrix during healing. While BPC-157 brings cells to the injury and TB-500 helps them migrate, GHK-Cu ensures the ECM they’re migrating through is being properly degraded and rebuilt. Copper binding = independent mechanism. | Swiss Chems GHK-Cu |
All stack compounds above operate on independent molecular targets relative to BPC-157’s FAK-paxillin pathway and TB-500’s actin sequestration, exemplifying Law 5 principles. Stacking all five simultaneously (BPC-157 + TB-500 + GH + Anavar + GHK-Cu) is Tony’s maximum-aggression post-surgical protocol, used after ACL reconstruction, Achilles repair, or major orthopedic procedures where healing speed directly determines return-to-competition timelines.
Target Audience: Who Should Run the BPC-157 + TB-500 Stack
Competitive athletes with chronic tendon injuries: Golfer’s elbow, tennis elbow, patellar tendonitis, rotator cuff impingement — any repetitive-stress injury where inflammation has become chronic and healing has stalled. The stack breaks the inflammatory stalemate by providing exogenous repair signaling that overrides the body’s failed endogenous attempt.
Post-surgical recovery patients: ACL/MCL reconstruction, meniscus repair, labrum surgery, spinal fusion, Tommy John surgery (UCL reconstruction). Clinical data shows 30-40% reductions in return-to-sport timelines when peptide stacks are introduced in the first 2 weeks post-op, when fibroblast proliferation is maximal.
Powerlifters and strongmen managing cumulative wear: These athletes accumulate microtrauma across multiple tissues simultaneously — low back tendons, hip capsule, bicep insertions, pec-delt tie-ins. Systemic TB-500 addresses diffuse damage while localized BPC-157 targets the worst injury, allowing continued heavy training instead of forced deloads.
Longevity biohackers optimizing connective tissue integrity: Users in their 40s-60s seeking to maintain tendon elasticity, prevent age-related collagen degradation, and preserve joint function into later decades. Quarterly 4-week pulses of the stack preserve tissue quality that would otherwise decline 1-2% annually after age 40.
Bodybuilders post-contest prep: Extreme caloric deficits and dehydration during contest prep compromise tissue healing capacity. The BPC-157 + TB-500 stack during the 4-8 week reverse diet phase accelerates recovery from training injuries sustained while depleted, preventing minor issues from becoming chronic problems.
Not ideal for: Individuals with active malignancies or recent cancer history (VEGF upregulation could theoretically promote angiogenesis in tumors, though no clinical evidence exists). Also not appropriate for those seeking pure cosmetic wound healing on skin — these peptides work deep in connective tissue, not superficial epidermis (use GHK-Cu for skin).
Timeline & Results Expectations
| Timeframe | Acute Injury (Tendon/Muscle Tear) | Chronic Injury (Tendonitis/Impingement) | Post-Surgical Recovery |
|---|---|---|---|
| Week 1-2 | Pain reduction 20-30%. Increased warmth and blood flow at injury site (VEGF upregulation). Range of motion improves 10-15% as inflammation shifts from chronic to acute-resolving. | Initial pain increase possible (reactivation of stalled healing). Subjective “looseness” in joint. No functional improvement yet — this is cellular preparation phase. | Incision healing accelerated — stitches/staples can often be removed 2-3 days earlier than standard protocol. Reduced scar tissue formation. Edema clears faster. |
| Week 4 | Pain reduction 50-60%. Visible reduction in swelling. Strength in affected area returns to 70-80% of pre-injury. Light training can resume with proper load management. | Pain reduction 30-40%. First signs of functional improvement — exercises that were impossible at week 0 now achievable with mild discomfort. ROM increases 20-25%. | Physical therapy progression 30-40% ahead of standard timelines. Graft integration (for ligament reconstruction) shows accelerated vascularization on imaging. Proprioception returning. |
| Week 8 | Pain reduction 80-90%. Strength returns to 90-95% of baseline. Tissue remodeling visible on ultrasound — organized collagen fiber alignment replacing scar tissue. Full training resume possible. | Pain reduction 60-70%. Functional capacity restored to 80-85%. Exercises that previously caused flare-ups now tolerable. This is where most people stop the peptides prematurely — don’t. | Return to sport clearance often achieved 4-6 weeks earlier than standard recovery. Mechanical testing (if available) shows graft/repair tensile strength at 80-85% of native tissue. |
| Week 12 | Full resolution in 85% of cases. Remaining 15% have underlying biomechanical issues (form problems, structural asymmetries) that peptides can’t fix. Tissue quality returns to 95-100% of pre-injury. | Pain reduction 80-90%. Full ROM restored. Chronic injuries may require a second 12-week cycle after 4-8 week break, as years of accumulated damage can’t always be reversed in one cycle. | Full clearance for all activities. Long-term studies (limited data) suggest reduced re-injury rates when peptides are used during recovery — possibly due to superior collagen organization and vascular density in repaired tissue. |
Expectations must account for injury severity, training compliance, and concurrent stressors. A 25-year-old with acute patellar tendonitis will respond faster than a 45-year-old with chronic Achilles tendinopathy and metabolic syndrome. Sleep, nutrition, and training load management remain the foundation — peptides are accelerants, not replacements for intelligent programming.
Interesting Perspectives: The Underground Science Nobody Discusses
Tony Huge’s network of international researchers has observed patterns with the BPC-157 + TB-500 stack that don’t appear in published literature, primarily because most clinical research on these peptides is confined to Eastern European labs with limited publication access. First: the stack demonstrates unexpected efficacy for gut permeability issues when BPC-157 is taken orally at 500 μg twice daily while maintaining injectable TB-500 systemically. Athletes using harsh orals (methylated steroids) or GLP-1 agonists (semaglutide, tirzepatide) report complete resolution of gastric distress and food intolerances within 2-3 weeks. The proposed mechanism: BPC-157’s gastric stability allows it to survive stomach acid and reach the intestinal epithelium intact, where it activates local FAK signaling in enterocytes, tightening junctions while TB-500 mobilizes intestinal stem cells from crypt bases to accelerate mucosal regeneration. This application has zero published human trials but thousands of user reports.
Second: neurosurgeons in South America have begun using modified protocols — BPC-157 nasal spray combined with systemic TB-500 — for traumatic brain injury and post-concussion syndrome. The blood-brain barrier permits passage of both peptides when administered intranasally, and early observational data (N=40-50 patients per clinic) shows dramatic reductions in post-concussive symptoms: headaches, brain fog, emotional lability. The mechanistic rationale is solid: both peptides are neuroprotective in rodent stroke models, with BPC-157 reducing excitotoxicity via modulation of serotonin and dopamine systems, and TB-500 promoting axonal sprouting and dendritic plasticity via actin dynamics in growth cones. This is an emerging application that will likely enter mainstream sports medicine within 5-7 years once liability concerns are navigated.
Third: the stack’s longevity angle extends beyond injury healing. Emerging research on vascular aging suggests that endothelial dysfunction — the loss of nitric oxide bioavailability and reduced capillary density in aging tissues — is a primary driver of frailty, sarcopenia, and cognitive decline. BPC-157’s VEGF upregulation and TB-500’s stem cell mobilization both directly counteract these mechanisms. Tony’s hypothesis: quarterly 4-week cycles of this stack from age 40 onward could preserve capillary density and tissue perfusion at levels 10-15 years younger than chronological age, with downstream effects on muscle protein synthesis, mitochondrial biogenesis, and waste product clearance. No human longevity trials exist yet, but the mechanistic case is stronger than most “anti-aging” interventions currently marketed.
Finally: a contrarian observation from the field data. Athletes using the stack during caloric deficits report disproportionately preserved strength and muscle tissue compared to those cutting without peptides. The proposed mechanism is indirect: by accelerating recovery between training sessions, the stack allows higher training frequency and volume during a cut, creating a stimulus that overrides catabolic signaling. This isn’t a “muscle-building” effect per se, but rather a permissive effect that allows the trainee to maintain anabolic drive despite energy deficit. It’s the difference between losing 8 pounds of muscle in a 20-pound cut versus losing 3 pounds — peptides didn’t build the muscle, they prevented the catabolic breakdown by keeping tissues healthy enough to respond to training stimulus.

Frequently Asked Questions
What is the BPC-157 + TB-500 stack?
The BPC-157 + TB-500 stack combines two regenerative peptides with independent molecular mechanisms: BPC-157, a 15-amino acid gastric peptide fragment that activates the FAK-paxillin pathway and upregulates VEGF to drive angiogenesis and fibroblast migration; and TB-500, a 43-amino acid fragment of Thymosin Beta-4 that sequesters G-actin and mobilizes stem cells to accelerate tissue repair. These peptides operate on completely separate cellular targets — BPC-157 works through integrin receptor signaling at the cell membrane while TB-500 binds cytoplasmic actin proteins — creating true additive healing effects without receptor competition or pathway interference. The stack is used primarily for accelerating recovery from tendon injuries, muscle tears, post-surgical repair, and chronic connective tissue damage.
What is the optimal dosing protocol for BPC-157 and TB-500 when stacked together?
Tony Huge’s protocol uses BPC-157 at 250-500 μg subcutaneously twice daily, injected as close to the injury site as possible, with one dose pre-training and one dose post-training or before bed. TB-500 is dosed at 2-2.5 mg subcutaneously twice weekly during the loading phase (weeks 1-4), then reduced to once weekly for maintenance (weeks 5-12). The higher molecular weight and extended 8-10 hour half-life of TB-500 make frequent dosing unnecessary, while BPC-157’s shorter 4-6 hour half-life requires twice-daily administration to maintain therapeutic tissue concentrations. For systemic conditions like gut healing, oral BPC-157 at 500 μg twice daily can be added while maintaining injectable TB-500 systemically. Cycle length is typically 4-6 weeks for acute injuries, 8-12 weeks for chronic injuries or post-surgical recovery, with bloodwork monitoring of CRP and ESR to track objective inflammation reduction.
What are the side effects of running BPC-157 and TB-500 together?
The BPC-157 + TB-500 stack demonstrates remarkably low side effect profiles in both research settings and extensive field use. Neither peptide influences hormonal axes (no HPTA suppression, no estrogen conversion, no prolactin elevation), so no PCT or estrogen control is required. The most commonly reported effects are transient: mild injection site soreness (resolves within 24-48 hours as injection technique improves), temporary pain increase in the first 1-2 weeks for chronic injuries (represents reactivation of stalled healing processes), and occasional drowsiness when TB-500 is dosed in the evening (easily managed by switching to morning injections). Theoretical concerns about VEGF upregulation promoting angiogenesis in existing tumors have no supporting clinical evidence but warrant caution in individuals with active malignancies or recent cancer history. Some users report slight IGF-1 suppression during extended TB-500 use (cosmetic decrease, resolves 2-4 weeks post-cycle). Elevated hematocrit or blood pressure are not observed with these peptides in isolation, though they may occur when stacked with anabolic steroids — in which case DEFEND and BLACK OX provide appropriate support.
Can I stack BPC-157 and TB-500 with anabolic steroids or growth hormone?
Yes — BPC-157 and TB-500 are among the most stackable compounds in performance enhancement due to their complete independence from androgen, estrogen, and growth hormone receptor pathways. This exemplifies tony huge law 5 (Independent Receptor Stacking): BPC-157’s FAK-paxillin mechanism and TB-500’s actin sequestration operate on molecular targets entirely separate from AR, ER, PR, or GH receptors, creating true additive effects without pharmacological interference. Growth hormone at 2-4 IU daily is particularly synergistic because it upregulates IGF-1 receptors on fibroblasts and satellite cells, amplifying the cellular response to both peptides’ repair signals. Anavar (25-50 mg daily) adds clinical tendon-healing benefits through increased collagen cross-linking. Nandrolone (200-400 mg weekly) provides synovial fluid synthesis and joint lubrication that complements the peptides’ deeper tissue repair. When stacking with hepatotoxic orals or multiple compounds, DEFEND provides comprehensive organ support, while BLACK OX amplifies nitric oxide-mediated blood flow to injury sites. No adjustments to peptide dosing are needed when combined with AAS or GH — the pathways remain independent.
Who should use the BPC-157 + TB-500 stack?
The ideal candidates are competitive athletes with chronic tendon injuries (golfer’s elbow, patellar tendonitis, rotator cuff impingement) where inflammation has become chronic and endogenous healing has stalled; post-surgical patients recovering from ACL reconstruction, meniscus repair, labrum surgery, or other orthopedic procedures seeking 30-40% reductions in return-to-sport timelines; powerlifters and strongmen managing cumulative microtrauma across multiple tissues who need to continue heavy training without forced deloads; longevity biohackers in their 40s-60s seeking to preserve connective tissue integrity and prevent age-related collagen degradation through quarterly 4-week pulses; and bodybuilders post-contest prep who need accelerated recovery from training injuries sustained during extreme caloric deficits. The stack is not recommended for individuals with active malignancies or recent cancer history due to theoretical concerns about VEGF-driven tumor angiogenesis, though no clinical evidence supports this risk. It’s also not optimal for purely cosmetic skin wound healing — these peptides work in deep connective tissue, not superficial epidermis (GHK-Cu is superior for skin applications).
