GHRP-2 vs Hexarelin
Both are gh secretagogue compounds. Here's how they line up on the evidence — graded the same way.
| GHRP-2 | Hexarelin | |
|---|---|---|
| Evidence | Preliminary human | Preliminary human |
| Class | GH secretagogue | GH secretagogue |
| Summary | GHRP-2 (pralmorelin) provokes a growth hormone pulse. It is an approved diagnostic in Japan, but the human therapeutic and anti-aging evidence is small and old. | A synthetic ghrelin-mimicking peptide that reliably spikes growth hormone in small studies, but was never approved and is banned in sport. |

GHRP-2
GHRP-2 is one of those compounds with a genuine, narrow medical use that has been stretched far past what the evidence supports. In Japan it is an approved diagnostic: a single dose provokes a measurable spike in growth hormone, which helps doctors test for growth hormone deficiency. Online, it is…
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…
