Specialty Peptide Research

A collection of specialized and emerging compounds that do not fit one therapeutic family. Use the individual evidence summaries to understand identity, proposed mechanism, safety uncertainty and regulatory status.

Educational research reference only, not medical advice. Evidence strength and regulatory status vary substantially between compounds.

AHK-Cu

AHK-Cu is a copper-binding tripeptide used mainly in topical scalp and skin products. It is discussed for hair-follicle signaling and dermal remodeling, not for whole-body hormone effects. Evidence lens: The evidence is…

Dermorphin

Dermorphin is a mu-opioid receptor agonist peptide. It belongs in the guide because it is a peptide, but it should not be grouped mentally with repair, cosmetic, or metabolic peptides. Evidence lens: The safety context…

GHK-Cu

GHK-Cu is a copper-binding tripeptide most defensibly discussed for topical/local skin and scalp signaling. Evidence lens: topical/cosmetic and local skin biology are not the same as systemic anti-aging, chronic wound…

IGF-1 LR3

IGF-1 LR3 is a modified insulin-like growth factor designed to last longer and bind IGF-binding proteins differently than native IGF-1. It is discussed for muscle growth and recovery, but the biology also overlaps with…

Melanotan I

Melanotan I is the older research name for afamelanotide, the active drug in SCENESSE. Unlike Melanotan II, it has an FDA-approved prescription form: a 16 mg controlled-release implant for adults with erythropoietic…

Melanotan II

Melanotan II is a melanocortin agonist best known for tanning and sexual arousal effects. Because it is nonselective, it can affect pigmentation, appetite, nausea pathways, sexual function, and cardiovascular/autonomic…
