Before ordering BPC-157, TB-500, or any research peptide, check for: A Certificate of Analysis (COA) for the specific batch/lot, not just a generic product-line COA Third-party HPLC (high-performance liquid chromatography) purity testing, ideally listing a percentage above 98% Mass spectrometry verification confirming the correct molecular structure Clear Research Use Only Not for Human Consumption labeling USA-based sourcing and domestic shipping, which shortens degradation risk during transit Suppliers who publish batch-specific COAs and welcome purity questions signal a more research-serious operation than suppliers who treat testing documentation as optional
The legal status of these peptides may change as regulatory agencies evaluate additional safety and efficacy data, and providers must stay informed about current regulations and requirements
