Comparison
The two best-known Khavinson bioregulators, sharing a research lineage, a course-based use pattern, and an evidence ceiling.
Epitalon is the longevity-framed tetrapeptide built on telomerase and melatonin claims; pinealon is the cognition-framed tripeptide with an older CNS report behind it. Both rest almost entirely on the same research lineage.
Epitalon (Ala-Glu-Asp-Gly) is claimed around telomerase activation and melatonin rhythm restoration. Pinealon (a tripeptide) is claimed around cognition and neuroprotection, anchored by an older Russian CNS clinical report.
Neither is strong, but they differ in kind: epitalon has in-vitro telomerase work plus small aging-population studies, while pinealon's human material is older and thinner. Neither has independent controlled trials.
Both follow the Khavinson course pattern, roughly 5 to 10 mg per day for 10-day courses repeated once or twice per year, because both come from the same research institute's protocol tradition rather than from dose-finding trials.

Epitalon has mechanism and review sources, but clinical longevity and sleep benefits have not been shown in outcome trials.
Pinealon is not a sleep treatment plan or sleep-loss workaround. EDR mechanism sources need to stay separate from REM, occasional-use, and combined-use claims.
