Where people buy these compounds

This page contains affiliate links, which means this site may earn a commission if you buy through them. It is kept separate from the calculator on purpose. The tool costs you nothing and does not change based on who pays.

What to check before you order

• A batch-specific certificate of analysis. A generic COA that is not tied to your batch number tells you nothing.
• Who ran the test. An in-house COA is a vendor marking its own homework. Third-party labs are the ones that matter.
• Stated purity and what the remainder is. 99% pure leaves 1% of something, and the COA should say what.
• Storage and shipping. Lyophilised powder is reasonably robust, but reconstituted product is not.

Vendors

Longer vendor write-ups, including what each one does and does not publish, are at Peptide Bureau, which is run by the same person as this calculator.
