How every Epitalon lot is tested
Before a lot is released, PrymaLab Analytical, our laboratory in Ashland, Kentucky, measures its purity by reversed-phase HPLC against a 99.0% specification and confirms its identity by LC-MS against the theoretical mass. The certificate is published with a certificate number and a key, so anyone can verify a printed copy or browse every Epitalon lot. These are in-house results.
Independent testing guarantee. Have any PrymaLab vial tested by an independent laboratory. If the result is not the compound named on the label, at the purity and amount stated, we refund the order in full and reimburse the cost of the test. Email the lab report and your order number to michael@prymalab.net.
