Peptide Sciences closed in early March 2026. To welcome researchers who need a new supplier, Pure US Peptide is offering 20% off your first order with the code below.
In early March 2026, Peptide Sciences posted a short notice stating it had decided to voluntarily shut down operations and discontinue the sale of its research products. No detailed public explanation followed, and we are not going to invent one — figures and causes circulating in this niche largely trace back to a single anonymous blog post and do not hold up. What is not in dispute is that a large base of independent researchers lost a familiar U.S.-based supplier. PSREFUGEE25 offsets the friction of switching vendors and re-validating supply.
