Description and reported dosing

What is Ipamorelin?

A growth hormone secretagogue acting on ghrelin receptors. It is singled out as the most selective of its class: at standard doses the available descriptions have it not meaningfully raising cortisol, prolactin or aldosterone, unlike the older compounds in the group.

Its plasma half-life is about 2 hours, and growth hormone peaks 30 to 40 minutes after a subcutaneous injection.
