BPC-157 vs Lion's Mane
Side-by-side of BPC-157 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.
BPC-157
BPC-157 peptide profile: pentadecapeptide body protection compound 157. Preclinical data on tendon, gut healing, recovery. No human RCTs as of 2026.
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
BPC-157
- •Preclinical models show accelerated tendon-to-bone and ligament healing after surgical or chemical injury
- •Rodent studies report mucosal protection and faster recovery from NSAID-induced and colitis-induced gut damage
- •Anecdotal human protocols use 250 to 500 mcg twice daily subcutaneously near the injury site
- •No completed phase II or III human RCTs as of 2026, so efficacy and long-term safety remain unestablished
- •Banned by WADA since 2022 under the S0 non-approved substances category for competitive athletes
- •Theoretical angiogenic concern means avoidance is prudent in active malignancy until human data exists
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

| Molecular formula | C62H98N16O22 | mixed extract |
| Mechanism | Proposed upregulation of VEGFR2 and nitric oxide pathways, modulation of growth-hormone receptor expression, and stabilization of gut-brain axis signaling. Mechanism remains largely preclinical. | Hericenones and erinacines stimulate NGF mRNA expression and NGF protein release in cultured neurons; secondary anti-inflammatory and remyelination-supportive activity in preclinical models. |
