CJC-1295 + Ipamorelin: The GH Peptide Stack I’ve Run for 4 Years (Honest Protocol)

If you ask me which peptide stack I’d take to a desert island, this is it.

Not BPC-157 — BPC is for when you’re hurt. Not Mots-c — Mots-c is for the mitochondria, which I love but which most people won’t notice the effect of for months. CJC-1295 paired with Ipamorelin is the one I’ve run consistently for almost four years, with breaks, and the one I notice when I’m off it.

This article is the actual protocol I run, the bloodwork that goes with it, the sleep and body-comp changes I’ve tracked, and the mistakes I made early on that I want you to skip.

Why GH Peptides Instead of HGH?

Synthetic HGH (somatropin) is the gold standard if you want to slam IGF-1 through the roof and force a supraphysiological growth response. It’s also expensive, illegal in most countries without prescription, and produces side effects — water retention, carpal tunnel, joint stiffness, blood sugar dysregulation — that scale brutally with dose.

GH peptides do something more intelligent. They tell your pituitary to release its own GH in a pulse. The pulse mirrors your body’s natural rhythm. You get the downstream effects (better sleep, better body composition, faster recovery, improved skin) without flatlining your endogenous GH production.

CJC-1295 is a Growth Hormone Releasing Hormone (GHRH) analog. It tells the pituitary “release GH.” Ipamorelin is a Growth Hormone Releasing Peptide (GHRP) — a ghrelin mimetic. It also tells the pituitary “release GH,” but through a different receptor. The two peptides hit different keys on the same lock and produce a synergistic pulse that’s larger than either one alone.

This is the cleanest GH-elevating protocol available outside of pharmacy-grade somatropin. And it doesn’t cost $1,500/month.

The Two Versions of CJC-1295 That Confuse Everyone

This trips up almost everyone new to the peptide.

CJC-1295 with DAC (Drug Affinity Complex) has a half-life of about 8 days. You inject once or twice a week and your GHRH receptor is being stimulated almost constantly. This sounds great until you realize that constant stimulation flattens the natural pulsatile pattern that makes GH effective in the first place. You get elevated baseline GH but your natural pulses get blunted.

CJC-1295 without DAC (also called Mod GRF 1-29) has a half-life of about 30 minutes. You inject it before bed, it stimulates a pulse, and it’s gone. Your natural rhythm is preserved.

I run CJC-1295 without DAC, exclusively. The DAC version has its place if you can’t inject daily, but the no-DAC version is what produces the cleaner, more natural GH pattern. This is the most common mistake I see new users make — they buy CJC with DAC because the dosing is easier and end up with a worse outcome.

For a deeper look at how peptides interact when stacked, my ultimate peptide stacking guide covers the principles I apply across every cycle.

The Protocol I’ve Actually Run

Here it is, no fluff.

CJC-1295 (no DAC): 100 mcg

Ipamorelin: 200 mcg

Combined into one injection: subcutaneous, abdominal fat, 29-gauge insulin pin

Timing: 60 minutes before bed, on an empty stomach (no carbs or protein for 90 minutes prior)

Frequency: 5 days on, 2 days off, OR 6 days on, 1 day off

Cycle length: 12 weeks on, 4 weeks off

That’s the whole protocol. There are people who add a morning injection and a post-workout injection — three pulses a day. I’ve run that. It works. It also turns peptide use into a part-time job and the diminishing returns kick in fast. One bedtime injection, done right, gives you 80% of the benefit for 33% of the effort.

The empty-stomach rule is non-negotiable. Insulin and GH don’t play nice — elevated insulin from a meal will blunt the GH pulse the peptide is supposed to produce. If you can’t go 90 minutes without food before bed, this is the wrong peptide for your lifestyle.

What I Actually Notice Within the First 12 Weeks

Week 1–2: Sleep gets deeper. This is the first thing every CJC/Ipamorelin user notices. You hit slow-wave sleep harder. You wake up less. If you wear an Oura or Whoop, you’ll see the deep sleep numbers climb the first week. This effect alone is worth the protocol for a lot of guys past 40 whose sleep architecture has degraded.

Week 2–4: Recovery between training sessions improves. I’m not talking about subjective “I feel better.” I’m talking about being able to push the same muscle group two days apart without the second session being garbage. Tendon and joint comfort goes up.

Week 4–8: Body composition starts shifting. This isn’t dramatic. CJC + Ipa isn’t a magic fat-loss peptide — it’s a body-recomposition peptide. You’ll see the visceral fat soften before the subcutaneous fat does. Your face will lean out. Your love handles will lag behind. By week 8, if your training and nutrition are dialed in, the mirror will tell you the protocol is working.

Week 8–12: Skin quality improves. This is the one most users don’t expect. Collagen synthesis is downstream of GH and IGF-1, and a 12-week run will produce visibly better skin tone, especially around the face. Older guys notice this more than younger ones because they have more degradation to reverse.

I’ve never run CJC + Ipa and not gotten these effects. The dose response is real and reproducible.

Bloodwork — What to Watch

This is the part that separates serious users from supplement-shop tourists.

IGF-1: Get a baseline. Run a 12-week cycle. Test again at week 10 (peak effect). I’ve seen IGF-1 climb 60–120 ng/mL from the protocol above, depending on starting baseline and age. If you’re not seeing IGF-1 movement, your peptide is underdosed (welcome to the research peptide market) or your protocol is wrong (food too close to bed, missed doses, DAC version).

Fasting glucose: GH antagonizes insulin. Fasting glucose can drift up 5–10 mg/dL on cycle. If you’re prediabetic, this protocol isn’t for you without a metformin co-prescription and tighter food timing.

Fasting insulin and HOMA-IR: Same reason. Track it. If insulin sensitivity tanks on cycle, drop the dose or shorten the cycle.

HbA1c: Run this at baseline and after a 12-week cycle. Should not move significantly if your protocol is clean. If it climbs more than 0.2 points, you’re either too high on dose, too long on cycle, or eating like you’re on prednisone.

For a complete framework on hormone-related labs and what they should look like for performance-focused men, the TRT and performance enhancement guide for men over 40 is the companion piece to this article — most of you running CJC/Ipa will be on TRT and the lab reading skills overlap heavily.

Mistakes I Made (So You Don’t Have To)

Running CJC with DAC because the dosing was easier. I did this for 8 weeks early on. Got elevated baseline GH and worse sleep. Switched to no-DAC and the protocol immediately worked.

Eating dinner too close to bedtime injections. Dinner at 8 PM, injection at 10 PM, GH pulse blunted. The first month I ran CJC/Ipa I didn’t take the empty-stomach rule seriously and I got mediocre results. Once I locked in the food timing, the protocol came alive.

Running too long without a break. I went 24 weeks straight once. Receptor desensitization is real. The cleanest results I’ve ever gotten were from 12 on, 4 off, repeat. Don’t try to outrun your own pituitary.

Cheap peptides. I wasted six weeks on a vendor whose Ipamorelin was probably 60% of label. Same warning as in the supplement contamination piece — at peptide doses this small, underdosing means you get nothing and assume the peptide is overhyped.

Stacking Considerations

CJC-1295 + Ipamorelin stacks beautifully with almost everything. Specifically:

With BPC-157 / TB-500: Synergistic for recovery. The GH pulse drives IGF-1, which drives tissue repair, which the BPC/TB-500 also drives through different mechanisms. This is a classic “hurt athlete” stack. The 8-week BPC/TB-500/GHK-Cu protocol layers cleanly on top of CJC/Ipa.

With TRT: No interaction. Run them in parallel. Your testosterone and GH systems are largely independent.

With MK-677 (Ibutamoren): Don’t. Pick one. MK-677 is an oral GH secretagogue that does largely the same thing. Stacking the two will give you GH receptor desensitization fast.

With MOTS-c: Excellent stack. CJC/Ipa for the systemic GH/IGF-1 push, MOTS-c for the mitochondrial side. Different mechanisms, complementary effects.

Cost Reality

Running this protocol cleanly will run you $80–$150/month for a 5-day-on schedule. That includes both peptides at the doses I described, plus pins and bac water. Compare that to $1,200+/month for a comparable HGH protocol and the math is friendly.

That said — if your peptides cost less than $40/month combined, they’re probably underdosed or contaminated. There’s a floor below which this market doesn’t produce real product.

The Verdict After Four Years

CJC-1295 + Ipamorelin is the closest thing to a no-downside peptide protocol I’ve found. The bloodwork stays clean if you respect the cycling, the sleep upgrade is reliable from week one, and the body composition response builds over the 12-week cycle in a way that compounds with smart training.

It’s not a beginner peptide. You need to be able to inject daily. You need to time meals. You need to actually run bloodwork. If you can do those three things, this is the GH peptide protocol I’d put in front of you over any other option that doesn’t involve a prescription.

I’ll keep running it. I’ll keep cycling it. And every time I’ve gone off it for the recovery period, the loss of sleep depth alone has been enough to remind me why I started.
