GHRP-2 vs Sermorelin
Both are gh secretagogue compounds. Here's how they line up on the evidence — graded the same way.
| GHRP-2 | Sermorelin | |
|---|---|---|
| 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. | Sermorelin is a synthetic GHRH fragment that nudges the pituitary to release growth hormone; human data is old and thin, with no modern anti-aging RCTs. |
