- GHK-Cu
- Copper-dependent upregulation of COL1A1/COL3A1 genes; MMP-1 downregulation; fibroblast proliferation
- 1–3 mg per injection
- 2–3 times per week
- Continuous (no cycling required)
- Human dermatology studies; proven collagen synthesis increase
- Epithalon
- Telomerase activation in somatic cells; pineal gland modulation; circadian rhythm regulation
- 5–10 mg per injection
- Daily for 10–20 days
- Pulse cycle 2x/year; 4–6 month rest between cycles
- Animal lifespan studies; no Phase III human trials
- Combined Stack
- Dual-pathway targeting: extracellular matrix repair + cellular replicative capacity
- GHK-Cu ongoing; Epithalon pulsed
- GHK-Cu 2–3x/week; Epithalon daily during cycle
- GHK-Cu year-round; Epithalon 10–20 day pulses
- No clinical trials on combined use; observational case reports only
