Peptides

Lyophilized Research Peptides — United States

A lyophilized peptide is a freeze-dried solid: the compound in a sealed vial with the water removed, which is what makes it stable at the molar masses these compounds have and why the research literature on them specifies the form. This shelf holds every single peptide and every peptide blend the catalog carries in that form, from the two-residue bioregulator fragments' larger cousins up to the 39-residue incretin analogues.

What distinguishes one entry from the next is structure, and each page publishes it: the amino-acid sequence, the CAS registry number, the molecular formula and the molar mass. A blend page lists each constituent peptide with its own identifiers and its own measured content, because a laboratory reports a blend compound by compound.

The batch code printed on the vial maps to an independent certificate for that lot. Two figures are read from it — HPLC purity, and measured content against the labelled amount — and both are shown on the product card before anything is added to a cart. Supplied strictly for laboratory research, shipped domestically within the United States.

What to check before buying peptides compounds

Purity is half the number. A purity figure tells you what fraction of the powder in the vial is the compound on the label — it tells you nothing about how much powder is in the vial. A lot can assay at 99.8% purity and still be short against its labelled content.

Both numbers are published for every batch here: purity from HPLC, and measured mass against expected content. Match the batch code printed on the vial to the certificate before you rely on either.
