Peptides are short chains of amino acids. They are commonly studied in biology, biochemistry, and related laboratory research.

Product pages identify the research material, available specifications, lot documentation, and Certificate of Analysis. Jarp Bio products are for qualified in vitro research only, not human or veterinary use, and we do not provide personal-use, safety, or medical guidance.

Every vial is labeled with its product, specification, lot number, and a QR code. You can scan the QR code or enter the lot number into our COA lookup to find the documentation for that vial before you use it in your research.

Yes. A randomly selected vial from each product variant in every lot is sent to an independent ISO 17025 accredited laboratory for reversed-phase HPLC purity and quantitation testing, and must pass with ≥ 98% purity, before any vial from that lot can be sold on our website.

A batch is a quantity of material made or processed during one production run. A lot is the traceable group of finished vials identified by its own lot number. The lot number on your vial is the number used to find its COA and related documentation.

A COA, or Certificate of Analysis, is a batch or lot specific laboratory report that verifies the identity, quality, and purity of a peptide. Basically, it confirms that the peptide is exactly what it says on the tin. All of our COAs feature a code you can enter on the lab's website to independently check the authenticity of the COA. Verify here.

Our products are not for personal, human, or veterinary use. We do not provide instructions for personal use and do not sell needles or syringes.

Some materials are supplied as freeze-dried (lyophilized) powder. Review the product and lot documentation for applicable storage and handling information. Liquid materials have different storage requirements.
