GLOW & Skin Protocol
GHK-CU (GLOW) and SNAP-8 (KLOW) — the skin aesthetic layer. Collagen synthesis, remodeling, and expression wrinkle research.
Mechanism of Action
Collagen Synthesis (GHK-CU)
GHK-CU upregulates Type I, III, VI collagen synthesis in fibroblasts — 70%+ increase in preclinical models. Simultaneously activates MMPs to remove damaged collagen while TIMP-1 protects new collagen.
VEGF Angiogenesis (GHK-CU)
VEGF upregulation drives new capillary formation in dermal tissue. Increased capillary density improves oxygenation and nutrient delivery — the physical basis of the luminosity/GLOW effect.
NMJ ACh Inhibition (SNAP-8)
SNAP-8 competes with SNAP-25 for SNARE complex binding at the neuromuscular junction, partially inhibiting ACh release. Lower contraction force → reduced expression wrinkle deepening.

GHK-CU 50mg
GHK-CU (copper peptide) 50mg — Clavicular's GLOW peptide. Upregulates 4,000+ genes involved in collagen synthesis, skin remodeling, and angiogenesis. Counteracts skin quality loss during aggressive fat loss. The aesthetic layer of the Clav stack. >98% purity.
CAS: 49557-75-7
GLOW & Skin: The Aesthetic Layer
Losing 28% body weight produces visible skin changes — both positive (facial definition) and challenging (skin laxity, collagen disruption). The Clav stack addresses this with two distinct skin peptides.
GHK-CU: GLOW Peptide
GHK-CU (glycyl-L-histidyl-L-lysine copper) is the most-studied injectable skin peptide in preclinical research. Clavicular calls it the GLOW peptide.
Key research findings:
- Upregulates 4,000+ genes involved in skin biology (Broad Institute)
- 70% increase in Type I, III, VI collagen in fibroblast models
- VEGF-driven angiogenesis → increased capillary density → luminosity
- Cu-SOD activation → antioxidant defense
- MMP activation removes damaged collagen while TIMP-1 protects new collagen
- Hair follicle: VEGF upregulation in dermal papilla
SNAP-8: KLOW Peptide
SNAP-8 (acetyl octapeptide-3) is a SNAP-25 N-terminal analog. It competes for SNARE complex binding at the neuromuscular junction, partially inhibiting ACh release → reducing expression muscle contraction force → reducing dynamic wrinkle depth.
Preclinical data: up to 63% reduction in expression wrinkle depth.
GHK-CU + SNAP-8 together:
- GHK-CU: structural collagen biology
- SNAP-8: neuromuscular wrinkle mechanism
Frequently Asked Questions
What is the GLOW peptide?
GHK-CU — a copper-complexed tripeptide that upregulates collagen synthesis genes, drives skin remodeling via matrix metalloproteinase activation, increases capillary density through VEGF upregulation, and activates Cu-SOD antioxidant defense. Clavicular's primary skin compound.
What is the KLOW peptide?
SNAP-8 (acetyl octapeptide-3) — a SNAP-25 analog that partially inhibits ACh release at facial NMJ, reducing the force of expression muscle contractions and the deepening of dynamic wrinkles.
