Quality
Quality & testing
Purity claims are worthless without the lab report behind them. Here’s exactly how every lot in our catalog gets verified before it’s listed.
Independent third-party testing
Every lot listed in our catalog is verified by an independent contract laboratory, not an in-house team with an incentive to pass its own product.
HPLC and mass spectrometry
Identity is confirmed by mass spectrometry; purity is quantified by HPLC peak-area analysis, the industry-standard method for peptide quantification.
Published, lot-specific COAs
Certificates of Analysis are tied to a specific lot number, not a generic template. Look any lot up directly at /coa/lookup before you buy.
No claims without paperwork
We do not list a compound with a purity claim we can’t trace to a signed lab report for that lot.
99%+ HPLC-area purity is the baseline we require before a compound is listed.
