Ipamorelin
Ipamorelin
Ipamorelin is the cleanest GH-releasing peptide — it triggers a growth hormone pulse without raising stress hormones like cortisol. Very popular paired with CJC-1295.
How Ipamorelin Works
A deeper look for the curious
For readers who want the full mechanism — feel free to skim.
Ipamorelin acts on the same receptor as ghrelin (the "hunger hormone") to trigger a clean pulse of growth hormone. What makes it special is selectivity — unlike other GH-releasing peptides, it doesn't bump cortisol, prolactin, or appetite much. Just a clean GH signal.
