10 mg nightly for 20 days, cycled 3x/year — the complete anti-aging protocol backed by a 52-week murine study
Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from epithalamin, a peptide extract of the pineal gland. It activates telomerase — the enzyme that rebuilds telomere caps on chromosomes — and normalizes melatonin production, reduces oxidative stress, modulates immune function, and improves metabolic parameters when administered cyclically. Studies demonstrate that Epitalon delays age-related changes in reproductive and immune systems, reduces neoplasia incidence, and enhances antioxidant defense.
Unlike most anti-aging interventions that target a single pathway, Epitalon acts on multiple aging mechanisms simultaneously: telomere maintenance, pineal gland regulation, oxidative stress reduction, and immune modulation. The cyclic administration pattern is key — it mimics natural biological rhythms rather than constant exposure.
Sixty aged male C57BL/6 mice (18 months at start) were randomized into vehicle control (saline) and Epitalon protocol groups (n=30/group). Treatment continued over 52 weeks until natural death or humane endpoint. All procedures complied with IACUC guidelines and ARRIVE 2.0 standards.
Dose
10 mg every night subcutaneously
Frequency
Daily for 20 consecutive days, cycled 3 times per year (e.g., January, May, September)
Route
Subcutaneous injection (evening, ~8 PM to align with pineal rhythm)
Mechanism: Activates telomerase to rebuild telomere caps, normalizes pineal melatonin production, reduces oxidative stress via enhanced antioxidant defense, and modulates immune function for systemic rejuvenation.
| Median Lifespan | Control: 912 ± 48 days | Epitalon: 1140 ± 55 days (+25%, p<0.01) |
| Frailty Index (Month 24) | Control: 0.28 ± 0.03 | Epitalon: 0.15 ± 0.02 (-45%, p<0.001) |
| Telomere T/S Ratio | Control: 1.00 ± 0.06 | Epitalon: 1.35 ± 0.08 (+35%, p<0.001) |
| ATP Production | +40% vs. control (p<0.001) |
| Oxidative Stress (ROS/MDA) | -45% vs. control (p<0.001) |
| Inflammation (TNF-α/IL-6) | -50% vs. control (p<0.001) |
| Cognitive Latency (Morris Water Maze) | -40% escape time vs. control (p<0.001) |
| Adverse Effects | None observed |
The cyclic regimen was highly efficacious and safe across all endpoints. No treatment-related adverse events were observed in any animals over the 52-week study period.
Typical 10 mg vial preparation:
| Dose | 10 mg subcutaneous every night before bed (~10 PM) |
| Duration | 20 consecutive days per cycle |
| Cycles | 3 per year (e.g., January, May, September) |
| Injection Sites | Abdomen, thigh, or upper arm — rotate daily |
| Technique | Clean site with alcohol; pinch skin; 45-90° angle; inject slowly |
| Monitoring During Cycle | Daily: sleep quality, energy, mood. Weekly: BP, resting HR |
| Post-Cycle Labs | Monthly: inflammation (CRP), oxidative stress, hormones, metabolic panel |
| Annual Goals | Stable/improved telomere length, CRP <1 mg/L, enhanced vitality |

Shop Peptide PartnersThe cyclic pattern — 20 days on, several months off — is critical to Epitalon's efficacy. This mimics natural biological rhythms and prevents receptor desensitization. Telomerase activation doesn't require constant stimulation; periodic activation is sufficient to maintain telomere length while allowing the pineal gland to normalize its own melatonin production between cycles. This makes Epitalon one of the most cost-efficient longevity peptides on an annualized basis.

Shop Peptide PartnersEpitalon is a synthetic version of the pineal peptide epithalamin. Published research demonstrates its ability to activate telomerase, extend telomeres, regulate circadian rhythm, enhance NK cell activity, and improve vascular function. It is considered a cornerstone of any longevity protocol.
