Epithalon (Epitalon) — Dosing, Cycles, Half-Life & Side Effects
Epithalon (Epitalon) is a longevity peptide with a half-life of Minutes. Synthetic tetrapeptide based on the natural epithalamin from the pineal gland. Claimed to activate telomerase and extend telomeres. Research primarily from Russian studies with limited Western validation.

Typical Dosing Ranges
Common dose range: 5-10mg/day for 10-20 days
Cycle length: 10-20 days every 3-6 months
Dose ranges are compiled from published pharmacokinetic studies and community-reported usage. Where a value is community-reported rather than clinically studied, this page and its structured data flag it. Lower end of any range is always the safer starting point.
Stacking Considerations
- No structural stacking blockers. Standard harm-reduction rules apply: minimize total androgen load, minimize oral exposure, and monitor bloodwork.
PCT Requirements
- Never stack two SERMs. Extend a single SERM (tamoxifen OR enclomiphene/clomiphene) rather than combining.
- Use the cycle planner to generate a full protocol based on your complete stack, not this compound alone.
Side Effect Profile
- Limited peer-reviewed human data
- Telomerase claims not fully validated
- Very short half-life
- Mechanism uncertain
- Primarily from Russian research
Known Interactions
No compound-specific interactions are catalogued in the current matrix. This does not mean no risk exists — it means there is no curated pairwise entry. Browse the full interaction matrix to cross-reference manually.

Monitoring (Bloodwork & Vitals)
- Comprehensive metabolic panel (baseline, mid-cycle, post-cycle)
- Lipid panel (total cholesterol, HDL, LDL, triglycerides)
- CBC (hemoglobin, hematocrit — watch for erythrocytosis)
- Sex-hormone panel (Total T, Free T, Estradiol sensitive, SHBG, LH, FSH)
- Blood pressure (weekly self-check; flag systolic >140 or diastolic >90)
Baseline bloodwork is recommended before any cycle. Discontinue if liver enzymes exceed 3× upper limit of normal or if hematocrit exceeds 54%.
