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.

Peptide Overviews
Ipamorelin
BHuman Studies
Ipamorelin is a selective growth hormone secretagogue that stimulates growth hormone release from the pituitary gland without significantly affecting cortisol or prolactin levels.

BHuman Studies
GHRP-6 was one of the first synthetic GH secretagogues developed. It stimulates strong GH release but also significantly increases appetite through ghrelin receptor activation.
