About this compound
The manufacturer tests both peptides in every batch of our BPC-157 + TB-500 blend by HPLC and mass spectrometry, to ≥99% purity. Those certificates are confidential under our supply agreement, so we cannot share them. Separately, we send selected batches to Janoshik, an independent lab, and publish every report on our lab reports page. Not every batch has an independent report, and each report names the batch it covers.
The blend is supplied as a lyophilised powder in a single sealed vial containing 20 mg of total peptide (BPC-157 10 mg, TB-500 10 mg). Prior to dispatch it is stored at −20°C. On receipt it can be kept in a refrigerator at 8°C or below, which will keep it stable for several months. For longer-term storage, keep it at −20°C, which allows storage for several years without affecting the compounds’ structure or purity.
Yes. All UK orders are dispatched via Royal Mail 24-Hour Tracked & Recorded. In-stock orders placed before 3pm are shipped the same day.
This blend is also known as BPC/TB, the BPC-157/TB-500 stack, and Body Protection Compound with Thymosin Beta-4. TB-500 here is the full 43-amino-acid Thymosin Beta-4 peptide (Tβ4), the same peptide as our standalone TB500 listing.
