High-purity research peptides, third-party verified by HPLC and mass spectrometry.
Research peptides are short chains of amino acids used in laboratory study — and their value depends entirely on purity.
A peptide is only useful to a researcher if it's actually the compound on the label, at the purity on the label. The problem across the industry is that most suppliers ask you to take that on faith.
REWERK exists to remove the guesswork. Each compound is synthesized, lyophilized into a sealed vial, and verified by independent analytical testing before it ships. The Certificate of Analysis isn't an add-on — it's the product.
High-purity research peptides in lyophilized (freeze-dried) powder form, sealed in sterile vials for laboratory use.
Identity confirmed by mass spectrometry, purity quantified by HPLC, then re-tested by an independent third-party lab.
A sealed, lyophilized vial, cold-chain shipped, with a Certificate of Analysis and a lot number you can verify online.
When a lot is produced, it goes through four checkpoints before it can ship. Mass spectrometry confirms the molecule. HPLC measures how pure it is. An independent lab repeats both. Only then is the lot released — and logged into a public library anyone can search.
