Research

Documentation you can actually use.

American-made reference materials

Every Apex Core RX peptide is sold strictly for in-vitro laboratory research. The pages below explain how we test, what a Certificate of Analysis includes, and how to request the paperwork for your lot.

Our lab standard

Peptides are prepared, purified, and QC-released in our lab so the label matches the lot.

Independent review

Third-party analysis sits on top of internal HPLC and mass spectrometry — not instead of it.

Lot-level COAs

Ask for the Certificate of Analysis by product or batch number before you start the work.

Certificates of Analysis

Certificate of Analysis on every lot

Each Apex Core RX batch is released with a lot-level Certificate of Analysis. Documentation typically includes appearance, identity, purity, molecular weight confirmation, batch number, and test date. Request the COA for your vial before you begin work.

Appearance

Physical description of the lyophilized material as released.

Identity

Sequence / compound confirmation against the labeled reference.

Purity

HPLC assay, typically ≥99% for catalog peptides.

Molecular weight

Mass spectrometry confirmation of the expected mass.

Batch / lot

The number printed on your vial, used to retrieve the matching COA.

Test date

When the lot was analyzed, so you can file it with your protocol.

Real science. Real standards. For every lab that demands both.

Purity shouldn't be a question mark. Verify every batch for yourself and see why researchers make the switch to Apex.
