Ipamorelin vs GHRP-6: Head-to-Head Comparison
Ipamorelin offers clean, selective GH release without hunger or cortisol spikes, while GHRP-6 is known for causing intense hunger due to strong ghrelin activity. GHRP-6 was one of the earliest GHRPs studied and remains popular for those who want appetite stimulation alongside GH release.
Side-by-Side Comparison
| Dimension | Ipamorelin | GHRP-6 |
|---|---|---|
| Evidence Level | Phase II trials | Extensive preclinical and clinical research |
| FDA Status | Not approved | Not approved |
| GH Release Potency | Moderate | Moderate to strong |
| Side Effects | Minimal; very selective | Strong hunger, cortisol and prolactin increase, possible dizziness |
| Appetite Stimulation | Negligible | Very strong (ghrelin-mediated) |
| Mechanism | Selective GHS-R1a agonist | Non-selective GHS-R1a agonist with strong ghrelin mimetic activity |
| Cost | Moderate | Low |
Peptide Overviews
Ipamorelin
BHuman StudiesIpamorelin is a selective growth hormone secretagogue that stimulates growth hormone release from the pituitary gland without significantly affecting cortisol or prolactin levels.
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.
