Peptide Sciences shut down on March 6, 2026. To welcome former Peptide Sciences researchers, Pure US Peptide is offering 20% off your first order with the code below.
On March 6, 2026, Peptide Sciences voluntarily shut down its operations after roughly fifteen months of escalating FDA enforcement against the broader research-peptide industry. With an estimated $7.4 million in December 2025 sales, the closure left a large base of independent researchers without a familiar U.S.-based supplier. PSREFUGEE25 offsets the friction of switching vendors and re-validating supply.
