Research Peptides
Short chains of amino acids, supplied lyophilized. Each is characterised by sequence, molecular formula and mass.
A research peptide is a short chain of amino acids made by solid-phase synthesis and purified by preparative HPLC, then freeze-dried. What arrives in the vial is that lyophilized powder, characterised by its sequence, its molecular formula and its mass, and nothing here describes what any of it does.
An independent lab tests every compound in this class before it goes on sale. The lab confirms it is the right compound and measures purity by HPLC. Each compound is tested by an independent lab, and the latest certificate is on its product page, so you can check the results before you order.
Compounds are grouped by what they are, not by what anyone plans to do with them. Sizes are milligrams of powder in the vial. Where the certificate reports net peptide content, the reconstitution calculator works out the peptide mass for you.

Common questions about research peptides
What does the milligram figure on a vial mean?
The weight of freeze-dried powder in the vial. Powder is peptide plus salts and water, so where the certificate reports net peptide content the peptide mass is the label figure multiplied by that percentage. A vial labelled 10 mg at 80 percent net peptide content holds about 8 mg of peptide.
How is purity measured?
By HPLC at 214 nm, reported as the share of the sample that is the compound. It describes the peptide part of the powder, not the whole powder, and it does not confirm identity on its own; that is a separate result against a reference standard.
Why are compounds grouped by what they are rather than what they are for?
Because grouping by use is a statement of intended use, and this site does not make one. Origin, length and what a compound binds are facts about the molecule that anyone can check.
Can I see the certificate before I order?
Yes. The latest certificate for every compound is on its product page and in the certificate archive. Read it before you order.
