GHRP-6 vs Hexarelin
Both are gh secretagogue compounds. Here's how they line up on the evidence — graded the same way.
| GHRP-6 | Hexarelin | |
|---|---|---|
| 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 synthetic ghrelin-mimicking peptide that reliably spikes growth hormone in small studies, but was never approved and is 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,…
Hexarelin
Hexarelin is a synthetic peptide that mimics the hunger hormone ghrelin to provoke a sharp, short-lived burst of growth hormone (GH). Small human studies in the 1990s showed it does this reliably, but every trial was tiny, brief, and measured surrogate markers rather than real-world outcomes. It…
