sermorelin vs sermorelin + GHRP-2

sermorelin (B-tier) vs sermorelin + GHRP-2 (D-tier). mechanism, trials, evidence boundaries, dosing literature. side-by-side reference.

sermorelin · tier B

Sermorelin is amidated GHRH(1-29). Its direct efficacy record is pediatric, while current adult sleep, recovery, and body-composition claims remain unproven.

People seek sermorelin for sleep, recovery, and body composition. An open-label pediatric study reported faster growth among 86 efficacy-evaluable children, not those adult outcomes.

86 efficacy-evaluable children · half-life 4.3 plus or minus 1.4 minutes after intravenous administration · growth hormone

sermorelin + GHRP-2 · tier D

This is a two-peptide combination of sermorelin and GHRP-2. One acute IV crossover found an additive GH response, not demonstrated synergy.

The exact human study measured a single IV hormone response in eight men. The combination was additive and did not establish sleep, recovery, body composition, repeated-subcutaneous safety, or a fixed product ratio.
