Lab testing & COAs.
Who tests our peptides, what they check, and every COA we have published.
Tested by an independent lab
Before any batch goes on sale, we send samples to an independent lab in the US. The lab confirms the peptide is what the label says and measures how pure it is, using two standard methods: HPLC and mass spectrometry. The lab's name is printed on the certificate of analysis (COA).
Your COA comes in the box
Every vial is printed with a batch number. The COA in your box is for that exact batch, so you always know which results go with which vial.
COA history, posted publicly
We post the COA for every batch below, newest first. Check the results before you buy, and compare batches over time. Each product page shows the history for that product.
Safety data sheets
We include a safety data sheet with your first order. Need another? Just ask.
