GHRP-6 vs Ipamorelin
Both are gh secretagogue compounds. Here's how they line up on the evidence — graded the same way.
| GHRP-6 | Ipamorelin | |
|---|---|---|
| Evidence | Preliminary human | Preliminary human |
| Class | GH secretagogue | GH secretagogue |
| Summary | An old growth-hormone-releasing peptide that reliably raises GH and appetite in humans, but whose marketed muscle, fat-loss, and disease claims lack solid trials. | A selective growth-hormone-releasing peptide with early human safety data but a failed efficacy trial; never approved and banned in sport. |

GHRP-6
GHRP-6 is one of the oldest synthetic growth-hormone-releasing peptides, and its basic pharmacology in humans is genuinely well understood: it raises growth hormone (GH) and it makes people hungry. What is missing is the part that actually matters for the claims attached to it. For muscle growth,…
Ipamorelin
Ipamorelin is a synthetic peptide that briefly raises growth hormone (GH) levels. It has been tested in humans, but the one trial that measured a real clinical outcome did not work, and it has never been approved for any use.
