Why BPC-157 Is a Research Staple
BPC-157 is a 15-amino-acid peptide with a molecular weight of 1419.5 Da, often described as a “body protection compound” because of its stability in gastric juice. That stability is one reason it appears frequently in preclinical tissue-repair research, and it also means storage and handling requirements differ slightly from more fragile peptides.
Because the sequence is short, synthesis is relatively straightforward — which means the market is crowded with low-quality batches. The purity problem, not the chemistry, is where most sourcing mistakes happen.
What to Verify Before Ordering
A legitimate BPC-157 supplier provides a batch-specific HPLC report (≥98%) plus a mass spec trace confirming the 1419.5 Da mass. Any vendor that won’t share both before payment is a red flag.
- HPLC ≥98%: the research-grade floor for this peptide
- Mass Spec: confirms the 1419.5 Da monoisotopic mass
- Vacuum-sealed vials: protects the lyophilized powder from moisture
- Clear fill weight: 5mg and 10mg vials are priced differently
Storage and Handling
Store lyophilized BPC-157 at -20°C, protected from light and moisture, and only reconstitute what you’ll use in the short term. After reconstitution, keep the solution refrigerated at 4°C and follow the supplier’s stability guidance.
FAQ
What is the molecular weight of BPC-157?
BPC-157 has a molecular weight of 1419.5 Da and consists of 15 amino acids.
What purity should research-grade BPC-157 be?
Accept ≥98% purity confirmed by HPLC as the standard. Below 97% indicates inadequate purification.
How is BPC-157 best stored?
Lyophilized BPC-157 should be kept at -20°C in a sealed, moisture-free vial. Reconstituted solution should be refrigerated and used promptly.
