| Mechanism (summary) | GHRP-6 is a synthetic GH secretagogue hexapeptide (His-D-Trp-Ala-Trp-D-Phe-Lys-NH2, MW 872.44 Da). In humans it is concentrated in endocrine challenge tests, diagnostic protocols, and mechanistic studies — particularly as part of the GHRH/GHRP-6 test for adult GH deficiency — rather than in therapeutic outcome trials. |
| Dosing notes | Best-supported accessible human dosing is 1 μg/kg IV, used in mechanistic and diagnostic testing — alone or combined with GHRH 1 μg/kg IV. These are test paradigms, not chronic therapeutic regimens. |
| Storage |
|---|
Primary publications did not provide GHRP-6-specific stability instructions in the retrieved literature. Generic peptide handling practice favors cold, dry storage of lyophilized material and avoidance of repeated freeze-thaw cycles after reconstitution. |
