FGL
NCAM mimetic peptide Preclinical only 3 cited studies 3 live vendors
An NCAM-derived peptide studied preclinically in neuronal plasticity and inflammatory-signaling models.
Evidence brief
FGL is a synthetic peptide derived from the fibroblast-growth-factor-receptor binding region of neural cell adhesion molecule (NCAM).
No separate best value by trust pick for FGL: none of the vendors selling it publish a certificate pepmg could open at a testing lab's own site. That is a limit on what we can check, not evidence they do not test — each vendor's own page shows exactly what they publish.

Multi-peptide products (e.g. BPC-157 + TB-500). We don't rank these by $/mgPrice divided by the milligrams of active compound — the like-for-like way to compare cost across different vial sizes. — a per-milligram figure across different peptides isn't comparable — so they're listed separately by total price and kept out of the headline index above.
