- GHK-Cu
- TGF-β activation, collagen synthesis
- Dermal structural protein density
- 1–3mg SC 2–3×/week or 0.5–2% topical
- 6–12 weeks for collagen density; 8–16 weeks for visible smoothness
- Strong. Multiple RCTs in wound healing and dermatology
- MOTS-C
- AMPK/PGC-1α signaling, mitochondrial biogenesis
- Cellular ATP production and oxidative capacity
- 5–10mg SC 2–3×/week
- 4–8 weeks for energy metabolism markers; 8–12 weeks for skin texture
- Moderate. Emerging human metabolic studies; limited dermatology trials
- Epitalon
- Telomerase activation, cellular senescence delay
- Epidermal turnover rate and stem cell proliferation
- 5–10mg SC daily × 10–20 days, cycled 2–3×/year
- 8–12 weeks post-cycle for turnover effects
- Limited. Strong animal longevity data; minimal human dermatology RCTs
- BPC-157
- Angiogenesis, VEGF upregulation, tissue repair
- Vascular density and nutrient delivery to dermis
- 250–500mcg SC daily
- 4–8 weeks for vascular markers; indirect skin benefits
- Moderate. Extensive tissue repair studies; no dedicated skin glow trials
- The combination creates a three-pathway protocol: GHK-Cu builds structure, MOTS-C powers cellular function, and Epitalon maintains regenerative capacity. Research groups occasionally add BPC-157 for vascular support, though its primary applications remain musculoskeletal and gastrointestinal tissue repair.
