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.
