GHRP-2 is a synthetic growth hormone secretagogue that has been found to bind to the ghrelin/growth hormone secretagogue receptor

Notably, NAM serves as the substrate for NAD + synthesis in the salvage pathway (Pissios, 2017)

This fine scale is ideal since many peptide doses are in the microgram range requiring only a few tenths of a milliliter

The good news is that if administered properly, any excess is excreted, so trying them (with a doctors oversight) may be low-risk
