Where can I buy the Wolverine stack?

Buy it from a supplier that can show a lot-matched certificate of analysis covering both peptides. COA-pep makes the Wolverine stack in a cGMP facility in Shenzhen, China, and every batch is tested by an ISO/IEC 17025 accredited independent lab. The panel covers purity by HPLC, identity by LC-MS, endotoxins, heavy metals and sterility, and batches typically test at 99% or higher.

Each vial carries a QR code tied to its lot, so you can pull its report from our COA library. Some suppliers sell a 7-residue fragment under the TB-500 name, so confirm the mass on any COA you compare. Orders placed before 3 PM ET ship the same or next business day. Shop BPC 157 TB 500 online.
