Journal
Plain-language notes on how peptides are tested, what a certificate of analysis actually proves, and how we set prices and handle batches that fail lab testing. Written to be read against any other seller in the category — not just us.
methodology
How to read a peptide COA from any seller — including ours.
Six things to look for on a certificate of analysis, and three red flags that mean the report does not prove what the seller claims it proves.
explainer
What "≥ 99 %" actually means on an HPLC report.
Why purity is harder to compare than it looks, why the wavelength matters, and what a single peak does and doesn't tell you about identity.
policy
The batches we destroyed this quarter, and why.
Three lots failed lab tests in Q1. Here is what they failed, what we did with them, and why we don't quietly sell off marginal product like the rest of the category does.
