pinealon vs epithalon

updated October 27, 2026

pinealon (tier C) vs epithalon (tier C): what each is, why each got its grade, half-life and source counts side by side.

pinealon · tier C

epithalon's sister from the same russian lab. neuroprotection claims, even thinner data.

tier rationale

C-tier because the compound sits almost entirely on theoretical plausibility and single-lab publications, with minimal clinical data even by Russian-research standards and no independent replication. The parent research program (Khavinson bioregulators) is real, and the in vitro work has some substance. But the leap from 'in vitro effects and theoretical BBB penetration' to the 'neuroprotective nootropic' product sold online is not supported by meaningful human evidence. Not D-tier because the underlying research program is legitimate and the mechanistic claims aren't absurd. They're just not demonstrated.

epithalon · tier C

russian longevity peptide. one lab. one cohort. the lifespan claims have never been replicated.

tier rationale

C-tier because the biology is plausible but the marketing has badly outrun the evidence. A real peptide from a real research program, with some mechanistic basis in pineal signaling and melatonin modulation. But the commercial sales pitch, telomerase activation and human lifespan extension, is the overreach. Single-lab data, single-cohort clinical trial, no Western replication. Community reports a sleep benefit that's probably real, but that's a much smaller claim than what vendors sell the compound on. Moves to B-tier only if independent replication of the telomerase or lifespan claims appears.
