Research Peptides You Can Trust

Research peptides are short chains of amino acids synthesized for use in laboratory and scientific research. They are not intended for human consumption and are sold strictly for research purposes only.

All Modus Club peptides are synthesized to a 99%+ target purity. Purity specifications are listed on each product page.

Peptides should be stored in a cool, dry place away from direct sunlight. Lyophilized (freeze-dried) peptides are stable at room temperature for short periods but should be refrigerated or frozen for long-term storage.

Yes. Our compounds are tested by an independent third-party laboratory using HPLC-UV for purity and LC-MS for identity confirmation. Certificates of Analysis are published directly on the product pages of tested compounds, showing purity, lot number and date tested. We are expanding testing across the catalog as new batches are analyzed.
