GHK-Cu + Epitalon — skin, hair, and cellular longevity.
A protocol pairing GHK-Cu, a copper-binding tripeptide that drives collagen and elastin synthesis, with Epitalon, a pineal peptide studied for telomere and circadian support. Together they address visible aging at the structural level and cellular aging at the longevity level.
Who it's for: Adults focused on visible aging — skin elasticity, hair density, connective tissue — and cellular longevity, particularly during and after hormonal transition.
RADIANCE pairs 2 compounds:
Glycine-Histidine-Lysine Copper Peptide
Naturally occurring copper-binding tripeptide that declines with age. Stimulates collagen and elastin synthesis, supports hair-follicle cycling, and modulates thousands of genes involved in tissue remodeling — one of the most evidence-backed peptides for skin and connective tissue.
Used for
Epitalon (Epithalon, Ala-Glu-Asp-Gly)
Synthetic tetrapeptide studied for effects on the pineal gland. Research suggests it may support telomerase activity, melatonin regulation, and circadian rhythm — a cellular-longevity complement to the structural effects of GHK-Cu.

The following reflects areas of interest commonly reported by members and studied in the clinical literature. Results depend on individual health status, labs, and physician-directed care. Nothing below constitutes a treatment claim.
GHK-Cu has one of the strongest research profiles in peptide medicine for collagen and elastin support — addressing the structural declines that drive visible skin aging.
GHK-Cu supports hair-follicle cycling and modulates gene expression across skin, hair, and connective-tissue pathways.
Epitalon adds a pineal, circadian, and telomere-research dimension — pairing visible aesthetic support with cellular-longevity signaling.
