Compare these compounds
Mechanism, evidence, legal path, cost — all side-by-side.
This compound sits in research-grey territory. The caveats below carry more weight than for FDA-approved entries — read them.
Geropharm / Khavinson lineage. Russian clinical literature reports use in immune restoration after surgery, infections, and aging-related immune decline. Mechanism overlaps with TA-1 but the specific peptide composition differs. Western clinical evidence near zero.
Thin data — the mechanism is biologically plausible, but human response evidence is mostly case reports and personal logs. If you're running this, careful tracking is not optional — it is the evidence base this tier is still building.
Russian-academy lineage. Western replication absent. Animal-tissue origin (TSE concerns). Counterfeit risk in grey-market sources.
