Typical — reference only
5-10 mg/day SC for a 10-20 day cycle, ~2-3x/yr (human trials used 0.5-1 mg/day - 10-20x lower)
Worked reconstitution example
10 mg vial + 2 mL BAC = 5 mg/mL; 5 mg = 100 U (full syringe); 10 mg/day = 200 U (two draws). Many use 10 mg/1 mL for easier dosing.
Units are not milligrams. mg-vs-mcg confusion drives documented 5–1000× overdoses — always recompute for your own vial (use the calculator →).
Removal from Category 2 ≠ legal to compound ≠ FDA-approved. FDA review is insomnia-scoped; a favorable vote would NOT validate longevity claims. FDA flags immunogenicity.

03Evidence — the honest read
Emechanistic / anecdotal
Single-lab (Khavinson) human data + one 2025 independent in-vitro replication (Brunel). Marquee mortality results were EPITHALAMIN (extract), not the synthetic tetrapeptide. 2025 review: human safety/PK 'missing.'
Contraindications
- Active/prior cancer (telomerase activation; precautionary)
- Pregnancy/breastfeedinghard stop
- Immune/autoimmune reactivity (FDA immunogenicity flag)
Key interactions
- Melatonin/sedatives (theoretical additive circadian effect)
Serious signals
- Cancer plausibility via telomerase (no human carcinogenicity data)
- 10-20x dose gap vs trials
Monitoring
None validated.
