GLP-1 drugs like semaglutide and tirzepatide are now common tools for cutting body fat. Athletes and serious lifters use them to keep hunger quiet so a deficit is easier to hold. The challenge is to stay strong and energetic while the scale moves. That is where stacking comes in. You pair one GLP-1 drug with targeted supports that protect training, recovery, and hormones.
This article shows exactly how to do that. You will see which add ons make sense, how they work at a high level, and when to use them. We cover peptides that help sleep and tissue repair, amino acids that defend muscle and pumps, and simple fueling rules that fit the way GLP-1 drugs slow the stomach. You will also get sample stacks for common goals like a deep cut, a long recomp, or performance first while leaning out.
Our lens is practical and athlete focused. Use the lowest effective dose of a GLP-1. Add tools that work through different pathways. Place food around training so sessions stay productive. Track a few signals each week and change one lever at a time. That is the Tony Huge way.
What a GLP-1 Stack Means
A GLP-1 stack is a plan to combine one GLP-1 drug with other agents that work by different pathways. You use only one incretin drug at a time. You then add support for insulin sensitivity, muscle protection, and workout energy. You avoid combos that just increase side effects.
Simple rules:
Use one GLP-1 drug, step the dose up slowly, and time food around training. Place bigger mixed meals after sessions so digestion does not fight your workout. Keep protein high every day.
- One GLP-1 only. Semaglutide or tirzepatide.
- Step up every two to four weeks if hunger returns.
- Weekly shot on a rest or easy day.
The Core Add Ons Most People Use
Metformin pairs well with a GLP-1 for many people. It supports insulin sensitivity and helps the liver handle glucose. Start with meals to limit stomach upset.
SGLT2 inhibitors can be layered for extra calorie loss through the urine and broad cardio‑renal benefits. Hydrate well and use electrolytes. Keep some carbs on hard training days. Speak with a clinician about rare ketoacidosis risk if you train low carb.
Skip overlaps that add side effects without better results.
- Do not combine two incretin drugs or add a DPP 4 inhibitor.
- Be careful with insulin or a sulfonylurea; doses often need to be reduced.
- Avoid unapproved compounded versions
Peptides That Pair Well With a GLP-1 Plan
Peptides can support recovery, joints, and focus while you cut. They work through different pathways than GLP-1 drugs, which is the point of stacking.
AOD-9604 targets fat breakdown more than growth. Many users notice easier waist and hip loss when diet and steps are consistent.
CJC-1295 + Ipamorelin raise growth hormone pulses. Bedtime use often deepens sleep and improves next‑day readiness.

BPC-157 is popular for tendon and gut support. A calmer gut also helps if your stomach feels slow on GLP-1 therapy.
TB-500 may aid soft‑tissue repair during high‑volume phases. Pair with mobility and extra sleep.
MOTS‑c is an experimental mitochondrial peptide; some report better stamina during cuts.
Semax or Selank can steady focus and mood on demanding days.
Amino Acids and Performance Supports
When hunger drops, smart aminos keep performance high.
Use 25 to 40 grams of high‑quality protein per meal to hit the leucine trigger. If solid food feels heavy, sip essential amino acids before you train and finish your protein after.
Add L‑carnitine L‑tartrate daily for fatty‑acid transport and less muscle soreness. Taurine and citrulline malate support hydration, blood flow, and pumps around workouts. Beta‑alanine helps with repeated high‑rep efforts; split doses to limit tingles. Glycine before bed can improve sleep and collagen support, while tyrosine pre‑workout sharpens focus when you skip stimulants. Do not forget electrolytes on hot or high‑volume days.
Top picks to prioritize:
- Citrulline pre‑lift for pumps and blood flow
- Taurine + electrolytes for hydration and cramps
- L‑carnitine and L‑tartrate for recovery during cuts
How GLP-1 Drugs Change Digestion and Fueling
GLP-1 drugs slow early stomach emptying. Large mixed meals can sit longer and feel heavy if you train too soon. Shift the big meal to after training and rely on small, low‑fat snacks beforehand.
- Keep large meals three hours away from hard sessions.
- Use easy options within one hour of training, like whey in water or a banana.
- During long work, use liquids or gels so the stomach does not slow you down.
Sample Stacks for Common Goals
Deep cut with joint protection
Run one GLP-1 at the lowest dose that keeps hunger quiet. Layer metformin. Use short cycles of AOD-9604 for stubborn areas and BPC-157 if tendons or gut need help. Keep protein at 1.8 to 2.2 grams per kilogram and put carbs around training.
Long recomp with high training volume
Use a modest GLP-1 dose so pre‑workout food still sits well. Consider an SGLT2 inhibitor with strong hydration and carbs on hard days. Add CJC-1295 + Ipamorelin at bedtime for sleep and recovery. Keep citrulline, taurine, and electrolytes around sessions.
Performance first while leaning out
Stay on the lowest GLP-1 dose that reduces snacking. Take creatine daily and a small pre‑workout protein‑carb feed. Place the largest meal post‑training. Use tyrosine for focus and Semax or Selank only on demanding days.
Dosing and Step Ups
Start low and move slowly. Hold each step two to four weeks so appetite and side effects stabilize. Anchor the weekly shot on a rest day and plan an easy day after if your stomach runs slow.
- Increase one step only when hunger breaks through.
- Hold or step down if nausea or reflux appears; fix meal timing and hydration first.
- Do not change dose and training volume in the same week unless necessary.
What to Track Each Week
Track a few signals and let them guide small changes.
- Morning weight and waist
- Sleep quality and resting heart rate
- Training markers like bar speed or pace at a fixed heart rate
Make one change at a time and give it one to two weeks before you judge.
Safety, Side Effects, and Red Flags
Common effects include nausea, fullness, reflux, constipation, and sometimes diarrhea, especially during dose increases. Smaller meals and less very fatty or very spicy food near workouts usually help. Some people should not use GLP-1 drugs, including anyone with a personal or family history of medullary thyroid cancer or MEN2. Work with a clinician and review the official labels.
Stop and get help if you notice severe belly pain that moves to the back, signs of dehydration, or a steady rise in resting heart rate with poor sleep and low mood.
Putting It All Together: The Tony Huge Way
Keep the stack simple and performance‑first. Choose one GLP-1, keep the dose as low as possible, and add only tools that work by different pathways. Protect training with carb timing, protein at every meal, and adequate electrolytes. Use peptides to support sleep, tissue health, and focus when needed. Track the basics and change one lever at a time.
Frequently Asked Questions on GLP-1 Stacks
Can I use semaglutide and tirzepatide together?
No. They hit the same GLP-1 pathway and raise side effects without clear proof of extra fat loss.
Is metformin a good add on?
Yes. It supports insulin sensitivity and pairs well with GLP-1 therapy for most people.
What peptides help the most during a cut?
For recovery and comfort, start with CJC 1295 plus Ipamorelin, BPC 157, and TB 500. For stubborn fat, try short cycles of AOD 9604. For focus, consider Semax or Selank.
Which amino acids should I prioritize?
Leucine rich protein, taurine, citrulline, glycine at night, and L carnitine L tartrate. Add electrolytes every training day.
How do I keep workouts strong when appetite is low?
Plan carbs before and after training, keep pre workout meals small and low fat, and sip fluids with electrolytes. Move your biggest mixed meal to after the session.
Are compounded GLP-1 products safe?
Avoid them. Use approved products and work with a clinician.
