The verdict

A four-amino-acid peptide developed in the Soviet Union by Vladimir Khavinson. Claimed to extend lifespan and lengthen telomeres. Almost all human data comes from one lab, in Russian, often unreplicated.

By source — cost, legality, risk

Brand
Not available
None — no FDA approval; no Western regulatory submission
No FDA-approved epitalon exists.
Compounded 503A pharmacy
$80–$200/mo where sold
Off-label · niche channel, not on bulks list
Mid–high. Few compounders carry; the Khavinson-only evidence base means legitimacy is weak.
RUO research peptide
$25–$80/mo
Sold 'for research only'
Highest. The dominant supply; small tetrapeptide is cheap to synthesize.
Gray-market raw
$35–$75/mo
Unregulated overseas import
Crypto/Wise pay; the 50mg×10 boxes ($176, $0.35/mg) are the bulk-buy tier — one box covers years at intermittent cycles.
