Comparison
Epitalon vs Lion's Mane
Side-by-side of Epitalon and Lion's Mane. Every row below is pulled from the compound schema and will update as our data grows. For deeper reads, follow through to each compound page.
Epitalon
Epitalon peptide (Epithalon, tetrapeptide AEDG): telomerase activation, lifespan extension data, anti-aging trials, dosage, half-life, and safety.
Lion's Mane
Lion's mane mushroom (Hericium erinaceus) supplement profile: hericenones and erinacines stimulate NGF in vitro. Human cognition trials are small.
Effects at a glance
Epitalon
- •Synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed at the St. Petersburg Institute of Bioregulation
- •Russian clinical literature reports mortality reduction in elderly cohorts and improved melatonin output
- •Reported telomerase activation in human somatic cell culture and lifespan extension in mice and Drosophila
- •Independent Western replication is essentially absent; no FDA-standard RCTs
- •Anecdotal protocols use 5 to 10 mg subcutaneously daily for 10 to 20 day cycles, 2 to 4 times yearly
- •Not currently on the WADA Prohibited List
Lion's Mane
- •Edible medicinal mushroom containing NGF-stimulating hericenones and erinacines
- •Mori 2009 trial (n=30) in mild cognitive impairment showed cognitive improvement at 3 g/day for 16 weeks, reversing 4 weeks after discontinuation
- •Saitsu 2019 (n=31) in older adults reported MoCA improvements at 3.2 g/day over 12 weeks
- •Multiple small mood trials suggest reduced anxiety and depression scores at 1 to 4 g/day extract
- •Mechanistic case rests on NGF stimulation and remyelination support; in vivo human NGF measurement is absent
- •Product quality varies substantially; mycelium-on-grain products can be over 50% grain by weight

Which Should You Take?
Lion's Mane comes out ahead for most readers on the criteria we weight: 3 catalogued goals, OTC dietary supplement, oral dosing, with a Tier-B outcome catalogued. Epitalon is the right call when one of the conditionals below applies.
- → If your priority is healthspan extension, pick Epitalon.
- → If your priority is sleep onset or sleep quality, pick Epitalon.
- → If your priority is focus or working memory, pick Lion's Mane.
- → If your priority is nerve health, pick Lion's Mane.
Edge case: If you want to avoid research-only / gray-market sourcing, Lion's Mane is the more accessible choice.
Default choice: Lion's Mane. Lower friction to source, and broader goal coverage. Reach for Epitalon only if your priority sits squarely in the goals it owns above.
