The combo
Why run them together
Epithalon is run in short ‘bioregulator’ courses for telomere/circadian/aging research; GHK-Cu is the standout skin peptide (collagen, repair) that also has hair and anti-inflammatory data. Together they cover ‘inside’ (systemic aging) and ‘outside’ (skin).
It’s a slow, cyclical stack — think maintenance, not overnight change.
Running it together
Community-reported dosing & timing for the pair (Reddit & forums) — logged for education, not a recommendation to use:
| Component | Community protocol |
|---|---|
| Epithalon | 10 mg subQ daily, in 10–20 day courses every 3–6 months |
| GHK-Cu | 1–2 mg/day subQ 5 days/wk, or a 1–2% topical serum |
| Cycle | Epithalon in short bursts; GHK-Cu in 8–12 wk blocks |
| Timing | Epithalon often at night; GHK-Cu daily |
The synergy
- Systemic longevity angle (Epithalon) + skin (GHK-Cu).
- Both dosed in cyclical courses, not continuous.
- GHK-Cu has the stronger evidence — set expectations by that.
Who it’s for
The longevity/skin crowd who want a slow, cyclical routine. As always: read each compound’s full guide, and talk to a clinician before running anything.
