- Not approved as a combo
- WADA ✗ S0
Combos are blends of separate compounds, so there is no single sequence. This ring motif is decorative — open a component for its fingerprint.
Evidence
- D In vitro
- C Animal
- B Human pilot
- A RCT
- S Approved
Not ranked: combinations have no published studies of their own. See the components below.
A PubMed search found no published studies of this combination; only reviews mention it. GHK-Cu is supported mostly by lab and topical-skin studies; glutathione has RCTs as a supplement.
Tiers rate the strength of published evidence — not effectiveness, safety, or a recommendation.

Overview
A skin-focused blend; in this catalog it means GHK-Cu combined with glutathione. Commercial products sold as “Glow” vary, and some instead combine GHK-Cu with BPC-157 and TB-500. Promoted for collagen support, oxidative protection, and skin radiance.
Research status Proprietary blend with variable composition; no published studies of the combination; evidence exists only for individual components
Mechanism
The Glow blend combines GHK-Cu-mediated collagen stimulation and extracellular matrix remodeling with glutathione-driven antioxidant protection and melanin modulation. GHK-Cu activates metalloproteinases for skin remodeling while glutathione neutralizes ROS and inhibits tyrosinase, producing complementary skin-brightening and anti-aging effects.
Effects reported in research
These outcomes are attributed to the individual components. The combination itself has not been studied.
- Enhanced skin luminosity and tone
- Increased collagen production
- Reduced oxidative skin damage
- Improved skin hydration and elasticity
Safety & unknowns
Individual components (GHK-Cu, glutathione) have well-documented safety profiles. Combination-specific safety data not available. Proprietary formulation varies by provider. Side effects expected to mirror those of individual components. Not FDA-approved as a combination.
Unknowns. The combination itself has not been studied; interactions between its components are unknown.

Randomized controlled trial of oral glutathione supplementation on body stores of glutathione
RCT on the glutathione component alone: 6 months of oral glutathione raised body glutathione stores; it did not study the blend.
