Every compound on WholePeps is independently tested by ISO/IEC 17025-accredited laboratories. Here's exactly how it works.
Vendors submit compound samples from each new batch alongside manufacturing documentation and synthesis records before any listing is approved.
Our QA team blind-labels all samples before dispatch to partner laboratories, ensuring no identification bias in the testing process.
High-Performance Liquid Chromatography measures compound purity to ±0.1% accuracy. Only batches ≥98% purity proceed.
Mass spectrometry confirms molecular identity by matching molecular weight and fragmentation patterns against reference standards.
Microbial contamination, heavy metals (ICP-MS), residual solvents, and other safety markers are tested to ICH Q3C limits.
Upon passing all tests, the laboratory issues a signed COA. We publish it directly on the product listing for full transparency.
