Frequently asked questions

What is a Certificate of Analysis (COA)?

A COA is the laboratory report for a batch: it states the measured purity (HPLC), the identity (mass spectrometry) and the batch details.

How pure are Virexa Labs peptides?

Every batch is tested for ≥99% purity by HPLC and for identity by mass spectrometry.

Does the COA match my vial?

Certificates are issued per batch. Contact customer service with your order number if you'd like the certificate for the batch of your own vial.

Are the peptides suitable for human use?

No. All products are intended exclusively for in-vitro laboratory research, not for human or veterinary use.
