On July 23 and 24, 2026, the FDA’s Pharmacy Compounding Advisory Committee reviewed seven peptides for the Section 503A Bulks List and recommended six of them. The committee voted against the recommendation of the FDA’s own multidisciplinary review team, which had advised against all seven. Coverage since has run from “the FDA approved BPC-157” to […]

A peptide is a molecule composed of two or more amino acids linked together by peptide bonds. It is the fundamental unit of protein chemistry and the subject of a large body of preclinical and biochemical research. Understanding what a peptide is, and how it differs from related molecule types, is useful context for anyone […]

Peptides have been at the center of biochemistry for over a century. The field’s key milestones run from the first laboratory synthesis of a peptide bond to the automation of peptide production that now supplies research compounds worldwide. 1902: The First Peptide Bond The concept of the peptide bond, the covalent link between amino acids, […]

The following glossary covers the most common terms encountered when reading about research peptides, COAs, and analytical testing. Definitions are framed for research contexts only. Core Chemistry Terms Amino acid The monomer unit from which peptides and proteins are built. Twenty standard amino acids are used by biology; each has an amino group (-NH₂), a […]

How to Vet a Research Peptide Vendor The research peptide market is uneven. Quality, documentation, and business practices vary widely between suppliers, and the burden of verification falls on the buyer. This guide outlines the criteria a research buyer can use to evaluate a vendor before placing an order. 1. A batch-specific Certificate of Analysis […]

Temperature exposure during shipping is a real source of peptide degradation. Here is how to evaluate what you received.

The two tests on every Vantage Aminos COA, what each one measures, and why both are necessary.

Why peptides ship as powder, what lyophilization actually does, and how storage temperature affects what you receive.

RUO is a regulatory classification with specific legal meaning. Understanding it matters before you order.

Reconstituting incorrectly degrades the compound before any research begins. This procedure covers the steps that matter.
