CJC-1295 and ipamorelin: what is actually in the vial

Sold as CJC-1295 w/o DAC + ipamorelin · CJC/Ipa · CJC-1295 no DAC ipamorelin blend · GH stack

The most widely sold peptide blend there is: a growth-hormone-releasing hormone analogue paired with a selective ghrelin-receptor agonist, on the reasoning that pushing the same axis through two different receptors produces a larger pulse than either alone.

2 compounds in one vial Weakest component: evidence 2/5 The combination has no human trial

No trial has tested this combination in people. Each compound below has whatever evidence it has, on its own. Putting two or three of them in one vial does not combine their evidence, and no study has looked at what they do together, in what order, or at what cost. Everything on this page about the pairing is a description of what is claimed for it, not a finding.

What is in it

Why it is sold this way

The pairing is justified on mechanism. The two components act at different receptors on the same pathway — one mimics growth-hormone-releasing hormone, the other mimics ghrelin at the growth hormone secretagogue receptor — and the combination is described as synergistic rather than merely additive. The "without DAC" qualifier matters and is frequently lost in the marketing: the drug affinity complex version has a far longer duration of action and a different pulse profile, and the two are not interchangeable.

What the combination actually has behind it

Both components raise growth hormone; that much is not seriously disputed and is measurable. What has never been established in a human trial is that the combination changes any outcome a person would notice — body composition, strength, recovery or injury risk — or that raising growth hormone in a healthy adult is beneficial at all. The evidence ratings on the two monographs below are both low, and combining two compounds rated that way does not produce a compound rated higher.

The blendNo human trial of the combination exists. The figure that matters for a mixture is its weakest component, which here is 2 of 5.

What mixing them makes impossible

A fixed ratio in one vial removes the ability to change one thing at a time. If it helps, it is not possible to say which component did it; if something goes wrong — water retention, numb hands, a rising fasting glucose, a reaction at the injection site — it is not possible to say which component caused it, or to stop one and keep the other. Neither is it possible to confirm that a vial labelled as two compounds contains either of them, let alone both in the stated proportion.

Change one thing at a time. This is the most useful rule on the safety page and a fixed mixture breaks it by design. If a blend helps, you cannot say which part helped; if it harms, you cannot say which part harmed, or stop that part alone.

Neither component is an approved medicine in the United States, and the compounding position of each is tracked separately in the dated record below.

Where each component sits in the FDA compounding record, as of 2026-09-15
CJC-1295 Category 2 — compounding not permitted Still in Category 2 of the 503A review, so not eligible for lawful pharmacy compounding in the United States. This compound is also the subject of the continuing litigation the record describes.
Ipamorelin Category 2 — compounding not permitted Still in Category 2 of the 503A review, so not eligible for lawful pharmacy compounding in the United States. This compound is also the subject of the continuing litigation the record describes.

The dated record for the compounds this site tracks is on the compounding status page, which is checked against the FDA's own documents rather than against anybody's description of them. A committee recommendation is not FDA action, removal from a list is not permission, and none of it is drug approval.
