Hexarelin

Hexarelin is the most potent ghrelin-mimetic growth hormone releasing peptide in this class. It produces the strongest GH pulse of any GHRP and has also been studied for a separate cardiac-protective effect - though that application is distinct from how it is typically used in peptide protocols. Its strength is both its advantage and its main limitation: the same potency that drives its GH effects also makes it prone to desensitization over time if used continuously. Hexarelin is primarily used for muscle building and recovery. It tends to be considered for short, focused performance phases rather than long ongoing courses. The desensitization issue is the key reason it is not treated as an everyday option the way ipamorelin is. Hexarelin is given as a subcutaneous injection at 100 mcg, one to two times daily, on an empty stomach. Its cycle structure specifically calls for short courses, because the receptors it acts on down-regulate with sustained use, reducing effectiveness over time. Prolactin also rises with prolonged use. Anyone with a cancer history should not use hexarelin. It should not be combined with MK-677. It stacks well with CJC-1295 (no DAC). Its evidence is classified as emerging, and it is available as a research or compounded preparation. Because of the desensitization dynamic and the importance of cycling correctly, hexarelin requires more attention to protocol design than a milder peptide like ipamorelin. Your licensed provider in the PepDepo network will assess whether hexarelin fits your goals and set the exact dose, duration, and any necessary breaks at your consult.
