- COA (Certificate of Analysis): the lab report for a lot; see how to read a COA and the COA library.
- HPLC purity: the main peak's share of total peak area; see HPLC vs mass spectrometry.
- Mass spectrometry (LC-MS): measures molecular mass to confirm identity.
- Net peptide content: the share of the powder that is peptide; see purity vs net content.
- Third-party testing: testing by an independent lab; see how it works.
Buying and pricing
- Kit: 10 vials of one compound and strength, the unit we sell.
