CJC-1295 vs ipamorelin
CJC-1295 · Ipamorelin
The short answer
They are not really alternatives, which is why the sellers bundle them. Both aim to raise your own growth hormone, through two different receptors, and the pitch is that together they produce a bigger release than either alone.
What neither has is human evidence that raising growth hormone produces the muscle, fat loss, recovery or anti-ageing outcomes they are sold for. Both raise a blood marker. Neither has been shown to make anyone better off.
Everything below goes into the detail, with sources on each record.
01Side by side
| CJC-1295 | Ipamorelin | |
|---|---|---|
| UK status | Unlicensed medicine | Unlicensed medicine |
| Availability | Research use only | Research use only |
| Evidence base | No human trials supporting marketed claims | Abandoned in development, no supporting human trials |
| Controlled drug | No, but WADA prohibited | No, but WADA prohibited |
| Drug class | GHRH analogue | Growth hormone secretagogue |
02What is the same
- Both unlicensed medicines in the UK. Supply for human use is prohibited.
- Both aim to raise your own growth hormone rather than injecting the hormone itself, which is a legally and pharmacologically different thing from somatropin.
- Both named explicitly on the WADA Prohibited List under S2.2.4. Prohibited at all times, and detection methods exist.
- Neither has controlled human trials supporting the marketed claims.
- Both are usually sold as a blend, which doubles every identity and purity question and makes it impossible to attribute any effect to either.
03What actually differs
| CJC-1295 | Ipamorelin | |
|---|---|---|
| What it copies | The instruction from the brain to release growth hormone | Ghrelin, which triggers release through a separate receptor |
| Receptor | GHRH receptor | Growth hormone secretagogue receptor |
| Size | Modified GHRH fragment | 5 amino acids |
| Duration | Days, in the DAC version. Minutes to hours without. | Short |
| Development history | Early human pharmacology, never completed | Entered human trials, then discontinued |
| Appetite effect | Not expected | Possible, since it acts on the ghrelin receptor |
Two different products are sold under this one name. The version with DAC binds albumin and acts over days. The version without DAC, often sold as Mod GRF 1-29, clears in minutes to hours. Sellers frequently do not specify which they are shipping, and that alone tells you something about the operation.
04What the evidence says
CJC-1295 has published early human pharmacology showing it raises growth hormone and IGF-1. So the mechanism is real. What does not exist is any controlled trial showing that this produces a benefit.
Ipamorelin has more pharmaceutical history: it was a genuine drug candidate, studied in humans including for gut function after surgery, and development was discontinued before approval. That means the programme which would have established its safety profile and a dose was never finished.
Clinics selling these often measure IGF-1 and present a rise as proof it is working. It is proof the compound is doing something. It is not proof that the something helps you, and there is no established safe target range for a healthy adult.
The FDA has flagged CJC-1295 as a substance with safety concerns for compounding purposes. Note that neither was on the July 2026 advisory committee docket, unlike BPC-157 and TB-500.
05Which suits whom
The question worth asking is not which of these to pick.
It is whether you have actually been tested for growth hormone deficiency through an endocrinology pathway. If you have, there is a licensed treatment, prescribed and monitored by a specialist. If you have not, you are raising a hormone with no evidence that doing so helps someone with normal levels, and with real questions about glucose handling and tissue growth over years.
If you compete in a tested sport, both end your season and strict liability applies.
06Getting either in the UK
Neither has MHRA authorisation. Both are sold as research chemicals labelled not for human consumption. Neither is a controlled drug, though growth hormone itself, the thing they are intended to raise, is a Class C controlled drug in the UK.
07The honest bottom line
Comparing these two is the wrong frame, because they are sold as a pair and the pair is the product.
The real comparison is between injecting a blend of two unlicensed compounds with no human outcome evidence, and doing something else. That is a decision the individual records are written to inform.
08Common questions
Why are CJC-1295 and ipamorelin sold together?
They act on two different receptors on the same gland, so the claim is that together they produce a larger growth hormone pulse. It also doubles the number of unverified compounds you are injecting from a single vial.
Which one is better?
Neither has controlled human trials supporting the outcomes they are sold for, so there is no evidence-based answer. Ipamorelin has more pharmaceutical history, having entered human trials before being dropped.
Do they show up on a drug test?
Yes. WADA names both under growth hormone releasing factors and secretagogues, prohibited at all times, and analytical methods exist for CJC-1295. There are no therapeutic use exemptions for unapproved substances.
Is raising your own growth hormone safer than injecting HGH?
It is legally very different, since HGH is a Class C controlled drug in the UK and these are not. It is not a demonstrated safety advantage, because the trials that would establish that were never done. Sustained elevation also differs from the natural pattern, which is pulses mostly at night.
