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.
▸ Why compare $/mg for LL-37?
Prices for this compound vary widely between vendors; comparing $/mg avoids overpaying.
▸ Reading the COA
Always check each vendor's third-party Certificate of Analysis (COA) for identity and purity.
