Peptides are short chains of amino acids that occur naturally in organisms, where they act as messengers in many biological systems. While some peptides have been developed for medical use, laboratory research focuses on understanding their activity at the cellular level, examining how they impact essential processes in vitro.

Products from Direct Peptides do not include usage instructions, as they are strictly for in vitro research and prohibited by law for human or animal use. Misuse or unlawful application will result in permanent denial of service. We are driven by the belief that high-quality materials empower meaningful discoveries—and we work every day to deliver the standards researchers depend on.

We ship all peptides in temperature-controlled packaging to maintain quality during transit.
