Why Vendor Selection Matters
BPC-157 is one of the most popular research peptides on the market — which also makes it one of the most counterfeited. With over 120 published preclinical studies [1], demand is high. But not every vendor selling “BPC-157” is actually selling what they claim.
5 Things to Look for in a BPC-157 Vendor
1. Purity ≥98% (Ideally ≥99%)
HPLC is the gold standard for peptide purity analysis. Any reputable vendor should provide HPLC data showing ≥98% purity. At MedTides, our BPC-157 is tested at ≥99% purity with batch-specific third-party COAs.
2. Third-Party Certificates of Analysis
A COA should come from an independent third-party laboratory — not in-house testing. Look for HPLC chromatograms and mass spectrometry data confirming molecular weight (1,419.53 g/mol). Generic PDFs without batch numbers are a red flag.
3. CAS Number and Molecular Data
Legitimate vendors list CAS: 137525-51-0, molecular formula, weight, and amino acid sequence. If absent, the vendor either doesn’t understand their product or doesn’t want you to verify it [2].
4. Research-Only Labeling
Any vendor marketing BPC-157 for human consumption or making health claims is violating FDA regulations. The FDA has specifically flagged BPC-157 for increased scrutiny [3].
5. US-Based Shipping
Domestic shipping means faster delivery, easier tracking, and no customs seizure risk. International peptide shipments are frequently held at customs.
The Bottom Line
Don’t buy the cheapest BPC-157 you can find. Buy the most transparent. A vendor that provides batch-specific COAs, lists CAS/molecular data, and doesn’t make health claims takes quality seriously. Your research results are only as good as the reagents you use.
