Batch Verification

Every batch we sell is independently tested by a third-party laboratory before it’s listed for sale. Each batch is assigned a lot number, printed on the vial label, in the format FF-XXXX-YYMMDD-NNN: a compound code, test date, and batch sequence.

To verify a batch, find the lot number on your vial and look it up in our Certificate of Analysis archive. Each certificate lists purity, test method, and the testing laboratory.

Products awaiting their first certificate are marked “Coming soon” or available for pre-order in the shop until testing is complete.
