Does pepmg track which payment methods vendors accept?

pepmg tracks price and lab-testing transparency, not checkout details. It does not track which payment methods a vendor accepts, whether that is card, bank transfer, crypto, or anything else, and those options are per-vendor and change over time.

To see how a specific vendor takes payment, that vendor's own site is the source. What pepmg compares is $/mg across vendors and who publishes third-party lab testing, never the payment rail.

All help topics · Answers restate pepmg's own pages; the linked section is the authority.

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.
