5 Amino 1MQ

Clean HPLC trace on our own column

Packaging arrived cold and intact, vials were correctly lot-numbered, and the certificate was easy to trace back to the batch.

J. Whitfield · Principal investigator · 1970-01-25

Premier Burn

Assay matched the COA exactly

Ran our own purity check on arrival and the number came back within a tenth of a percent of the published certificate. That kind of agreement is rare with a new supplier.

Dr. M. Callahan · Research director · 1970-01-23

Enclomiphene

Fast dispatch, packed cold

Verified

Documentation is more complete than most vendors we've used. Having identity, water content and endotoxin figures up front saves us a qualification step.
