These figures are what pepmg still publishes about price: the floor, the middle, the spread and how many sources we track, computed from listings we captured first-party and refreshed on the same schedule as always. We no longer publish the individual listings or the sellers behind them.

Computed from 39 in-stock listings across 34 sources we captured first-party, with bulk vials, blends and statistical outliers excluded so the figures compare like with like. The spread is the highest tracked price divided by the lowest — how much the same milligram varies depending on where you look. The chart is the daily minimum; days we did not capture are left out rather than filled in.

COACertificate of Analysis: a lab report stating a batch's measured identity and purity. availability: 33 of 34 sources selling LL-37 publish a COA — 16 with at least one certificate you can open at the testing lab. What a COA proves →
Blends & stacks: 2 first-party multi-peptide products contain LL-37 , priced $125.00–$693.00 per unit. 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 stay out of the figures above.

All products listed are sold by third-party vendors for laboratory and research use only (RUO). Where an FDA label or a peer-reviewed study has published a dose, pepmg reports it with the source named, because that is safer than guessing. It is a report, not medical advice and not a recommendation to use anything. pepmg sells nothing and ships nothing. Listings are price-tracking data, not endorsements.
