The supplier confirms the final price and availability when you order. Product names, photos, quantities and prices are as publicly listed by the supplier; photos load from the supplier’s own website. “vs market” compares price per mg with the median across tracked suppliers listing the same peptide in the same currency; prices are never converted between currencies. We do not sell these products and give no guidance on their use.
