Epithalon
Grade CRussian preclinical and small-cohort human studies reported lifespan and biomarker improvements. Independent replication is limited.

Tetrapeptide (Ala-Glu-Asp-Gly) hypothesized to upregulate telomerase activity and normalize pineal melatonin secretion.
Educational reference only — not medical advice.
Epithalon is administered subcutaneous, intranasal with an approximate systemic half-life of Short, hours. Steady-state and tissue-level effects can outlast plasma concentration, which is why dosing frequency (Daily) is designed to match receptor kinetics rather than plasma exposure. Tetrapeptide (Ala-Glu-Asp-Gly) hypothesized to upregulate telomerase activity and normalize pineal melatonin secretion.
Sterile technique is not optional. Use a fresh needle for every injection.

Grade C — mechanistic hypothesis and animal or in-vitro data only. No controlled human trials. Treat as experimental; risks are not fully known.

5–10 mg, Daily, for 10–20 day cycles, 2× per year. Route: Subcutaneous, intranasal. Timing: Evening. Half-life: Short, hours.
Tetrapeptide (Ala-Glu-Asp-Gly) hypothesized to upregulate telomerase activity and normalize pineal melatonin secretion.
Most users track a full 10–20 day cycles, 2× per year cycle before judging response. Subjective changes can appear within 1–3 weeks, but objective biomarker shifts typically need the full cycle plus repeat labs.
Research chemical; not approved for human use.
Largely unknown long-term; Injection site reactions.
Commonly combined with: Magnesium glycinate, Glycine. Introduce one compound at a time to preserve attribution.
Baseline and post-cycle: full blood count, comprehensive metabolic panel, and category-specific markers for longevity peptides (see the monitoring section on this page).
Off-cycle periods let receptor sensitivity and endogenous feedback normalise. Continuous dosing without a wash-out typically produces diminishing returns and a poorer safety margin.
