AHK-Cu
Summary
Pinealon is a synthetic tripeptide (Glu-Asp-Arg) developed by the St. Petersburg Institute of Bioregulation, designed to penetrate the blood-brain barrier and exert neuroprotective, neurogenic, and anti-aging effects by regulating pineal gland and brain cell function.
AHK-Cu is a copper tripeptide composed of alanine, histidine, and lysine chelated to copper. Distinct from GHK-Cu, AHK-Cu exhibits strong affinity for hair follicle receptors and demonstrates potent hair growth stimulation alongside wound healing and skin regeneration properties.
Half-Life
Short (peptides rapidly degraded), but epigenetic/gene regulatory effects persist
Hours (topical, variable by formulation)
Admin Route
SubQ, Oral, Intranasal
Topical, Scalp application, Subcutaneous (research)
