Peptide Terms Explained for Filipinos: COA, HPLC, BAC Water & More

New to peptides in the Philippines? Here are 13 terms from labels and lab reports, in plain English. Amino acid: a building block of proteins. There are 20 kinds.

Peptide: a short chain of amino acids, typically 2 to 50, linked by peptide bonds. Vial: the small sealed container the peptide ships in. Milligrams, or mg, on a vial label: the total compound the whole vial is stated to contain. It describes the vial only.

Lyophilized: freeze dried, so the peptide is more stable as a dry powder. Useful in Philippine heat. BAC water: bacteriostatic water, sterile water with a benzyl alcohol preservative. COA: certificate of analysis.

A lab document recording test results for a batch. Batch, or lot: one production run, tracked by a code. The code on the vial should match the report. HPLC: a lab method that separates a sample into its parts.

Purity: the share of what HPLC detects that is the target peptide. Endotoxin: bacterial cell wall fragments, measured in endotoxin units, or EU. Agonist: a substance that binds to a receptor and activates it. A GLP-1 receptor agonist activates the GLP-1 receptor.

Half-life: the time for a substance's concentration in the body to fall by half. From Metro Manila to the provinces, these words mean the same on every report.
