At Least 99% HPLC Purity Floor

What the floor means

Biscayne Science states at least 99.0% purity by HPLC on every compound, with mass-spectrometry identity and endotoxin screening. The lot-matched Certificate of Analysis is where the batch result for your vial is written down.

Why the certificate still matters

A floor is a minimum the supplier states. The certificate is the result for one lot. Those are different sentences. You want both: the policy, and the number for the vial you have.

Illustrative example. The homepage shows a sample Certificate of Analysis layout for BPC-157 at 99.4% HPLC. That percentage demonstrates the report format. It is not the result for a customer’s lot. Do not treat any example on the homepage as your batch.

Read it with the other tests

HPLC purity is one line. Mass spectrometry confirms identity. Endotoxin is reported separately, under 0.25 EU/mg. Each batch is tested for sterility. The HPLC and mass spectrometry note walks through the first two.

Questions researchers ask

Is 99% the result on my certificate?

No. At least 99% is the floor. Your certificate shows the HPLC result for your lot, which may be higher. An example such as 99.4% on the homepage is illustrative only.

Where is the floor stated?

On the Biscayne Science homepage and on these research notes: at least 99% by HPLC for every compound.
