GHRP-2 vs GHRP-6
Both are gh secretagogue compounds. Here's how they line up on the evidence — graded the same way.
| GHRP-2 | GHRP-6 | |
|---|---|---|
| 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. | 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. |

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…

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,…
