Skin, hair, and antioxidant support
GHK-Cu + Glutathione — collagen synthesis meets master antioxidant.
About this protocol
A pairing that addresses skin and hair from two angles: GHK-Cu drives collagen synthesis and tissue remodeling at the gene-expression level, while injectable Glutathione provides systemic antioxidant defense at bioavailability oral forms can't match.
Who it's for: Adults focused on visible aging markers — skin elasticity, hair density, antioxidant status — particularly during and after hormonal transition.
What's in this protocol
RADIANCE pairs 2 compounds:
GHK-Cu
Glycine-Histidine-Lysine Copper Peptide
Naturally occurring copper-binding tripeptide that declines significantly with age. Stimulates collagen and elastin synthesis, supports hair follicle cycling, modulates over 4,000 genes involved in tissue remodeling.
Used for
Glutathione
L-Glutathione (injectable)
Body's primary endogenous antioxidant — a tripeptide synthesized in every cell. Injectable form bypasses first-pass metabolism, delivering systemic antioxidant capacity oral forms can't reliably reach.

What members are working toward
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.
Collagen and skin elasticity
GHK-Cu has one of the strongest research profiles in peptide medicine for collagen and elastin support — addressing the structural protein declines that drive visible skin aging.
Hair follicle cycling
GHK-Cu has been studied for its role in hair-follicle stimulation and the cycling between growth and rest phases — relevant for members noticing thinning related to hormonal transitions.
Systemic antioxidant defense
Glutathione directly neutralizes reactive oxygen species and regenerates vitamins C and E. Injectable bioavailability is meaningfully different from oral.
Tissue remodeling
GHK-Cu modulates gene expression across thousands of pathways involved in skin, hair, and connective tissue health — a unique signaling reach among studied peptides.
