GHRP-2 vs GHRP-6: Head-to-Head Comparison
GHRP-2 and GHRP-6 are closely related ghrelin mimetics. GHRP-2 is more potent for GH release and causes less hunger, while GHRP-6 is known for its intense appetite stimulation. Both raise cortisol and prolactin, but GHRP-6 does so to a lesser degree than GHRP-2.
Side-by-Side Comparison
| Dimension | GHRP-2 | GHRP-6 |
|---|---|---|
| Evidence Level | Extensive clinical research | Extensive clinical research |
| FDA Status | Not approved | Not approved |
| GH Release Potency | Higher GH output per dose | Moderate GH output |
| Appetite Stimulation | Moderate hunger increase | Very strong hunger increase |
| Cortisol/Prolactin Impact | Moderate increase in both | Mild to moderate increase |
| Mechanism | Non-selective GHS-R1a agonist | Non-selective GHS-R1a agonist, stronger ghrelin mimetic |
| Cost | Low to moderate | Low |
Peptide Overviews
GHRP-2
BHuman StudiesGHRP-2 is a synthetic hexapeptide growth hormone secretagogue. It is one of the most potent GHRPs and has been used in clinical research for GH deficiency diagnosis.
GHRP-6
BHuman StudiesGHRP-6 was one of the first synthetic GH secretagogues developed. It stimulates strong GH release but also significantly increases appetite through ghrelin receptor activation.
