Dose
No human dose established
Amounts that circulate in forums and on vendor pages are not a human dose. Amounts that were given in studies sit in Human evidence on this page.
Commonly reported amounts, in mcg. Ipamorelin has no approved label.
Amounts commonly reported by people buying Ipamorelin, recorded for this archive's reconstitution calculator, are 100, 200 and 300 mcg. They are self-reports rather than trial doses, and this archive does not recommend any of them. No human dose has been established for Ipamorelin.
| Reported amount | Where the number comes from |
|---|---|
| 100 mcg | Commonly reported, no published human dosing trial |
| 200 mcg | Commonly reported, no published human dosing trial |
| 300 mcg | Commonly reported, no published human dosing trial |
Dose
No human dose established
Amounts that circulate in forums and on vendor pages are not a human dose. Amounts that were given in studies sit in Human evidence on this page.
Commonly reported amounts for the no-DAC form, in mcg. The DAC form is usually reported in mg per week: enter that and switch the unit to mg.

Column A
IpamorelinIpamorelin Acetate
A peptide that tells the pituitary gland to release growth hormone in natural bursts. It barely touches cortisol, the stress hormone, or prolactin.
Column B
CJC-1295CJC-1295 (GHRH analogue)
A lab-made copy of the body's growth hormone releasing signal, built to last longer. It keeps growth hormone and IGF-1 raised for days.
Side by side, on the facts we can check
| What we compare | Ipamorelin | CJC-1295 |
|---|---|---|
| Category | Growth Hormone | Growth Hormone |
| FDA status | Not FDA-approved | Not FDA-approved |
| Half-life | ~2 hours | ~6-8 days (DAC version) |
| Molecular weight | 711.85 Da | 3,647.2 Da |
| How it works | It switches on the ghrelin receptor on the pituitary gland, also called GHS-R1a. Ghrelin is the body's hunger hormone. Switching on this receptor makes the gland release growth hormone in bursts. | It switches on the GHRH receptor on the pituitary gland, which makes the gland release more growth hormone. The DAC version sticks to albumin in the blood, so it keeps working longer. |
| Studies in people | 3 | 4 |
| Evidence | Moderate: 2 completed trials, 157 people given it | Limited: 2 completed trials, none stating how many people |
| Legal status, US | Not approved; research use only | Not approved; research use only |
Frequently asked questions
What is the difference between Ipamorelin and CJC-1295?
Ipamorelin: A peptide that tells the pituitary gland to release growth hormone in natural bursts. It barely touches cortisol, the stress hormone, or prolactin. CJC-1295: A lab-made copy of the body's growth hormone releasing signal, built to last longer. It keeps growth hormone and IGF-1 raised for days.
Which has stronger research evidence, Ipamorelin or CJC-1295?
Each compound gets a band worked out from facts we counted, with the math shown. Ipamorelin is Moderate (2 completed trials, 157 people given it). CJC-1295 is Limited (2 completed trials, none stating how many people). That counts how much has been done in people. It does not rate whether either one works, and neither one is called the winner.
Are Ipamorelin and CJC-1295 FDA-approved?
Ipamorelin: Not FDA-approved. CJC-1295: Not FDA-approved.
