Hexarelin vs 5-Amino-1MQ

Side-by-side comparison of key properties, dosing, and research.

Growth Hormone Peptides
Hexarelin
Fat Loss & Metabolic
5-Amino-1MQ
Summary
Hexarelin is a potent synthetic GHRP and the strongest GH secretagogue in its class per unit dose. It also exhibits unique cardioprotective properties through direct binding to cardiac CD36 receptors, independent of GH release. Its potency is balanced by a tendency to desensitize GH release with prolonged use, making cycling important.
5-Amino-1MQ is a small-molecule NNMT (Nicotinamide N-methyltransferase) inhibitor that raises intracellular NAD+ levels and promotes fat burning. It is notable for targeting adipose tissue directly, reducing fat cell size and number while increasing metabolic rate.
