    Reading a vial label

    What to check on a research vial when it arrives: the compound name, the strength in milligrams, and how a kit of ten vials fits together.

    How peptides are made

    Most research peptides are built by solid-phase synthesis, one amino acid at a time on a resin bead. A plain-language walk through the method.

    Peptide names and abbreviations, explained

    Why peptides have names like CJC-1295 without DAC and GHK-Cu, and what the letters, numbers and milligram figures on a product usually mean.

    GLP-1, GIP and glucagon receptors, explained

    What a receptor is, what an agonist does, and how laboratories measure the activity of compounds that act on the GLP-1, GIP and glucagon receptors.

    What is tirzepatide?

    Tirzepatide is a synthetic peptide that activates two receptors, GIP and GLP-1. A plain-language look at the compound and how it differs from retatrutide.

  • 28 October 2026

    What is retatrutide?

    Retatrutide is a synthetic peptide that activates three receptors: GIP, GLP-1 and glucagon. A plain-language look at what that means in the lab.

    How to store peptide vials in the lab

    Cool, dry and dark: how laboratories store freeze-dried vials, and what changes once a peptide has been reconstituted.

  • 26 October 2026

    What is a lyophilized peptide?

    Lyophilized means freeze-dried. Why peptides are supplied as a dry powder, how freeze-drying works, and what it means for handling.

    What is bacteriostatic water?

    Bacteriostatic water is sterile water with 0.9% benzyl alcohol added. Why laboratories use it as a diluent, and how it differs from plain sterile water.

    How a freeze-dried peptide is reconstituted in the lab

    Reconstitution means dissolving freeze-dried peptide in a diluent. The usual laboratory steps, from a clean workspace to labelling and cold storage.
