Lyophilized Peptides: These peptides are freeze-dried, a process that not only extends shelf life but also preserves the purity and integrity of the peptides during storage.

Non-Lyophilized Peptides: Offered as a dry powder, these peptides, while not as extensively processed as lyophilized peptides, still maintain a high level of purity. Their stability, though not as enhanced as in lyophilized form, is sufficient for maintaining quality under proper storage conditions.

Understanding Our Product Grades

We offer three distinct product grades to support varying research needs. Our Premium Lyophilized line is triple-tested for purity, endotoxins, and sterility, and in most cases includes both double third-party testing and manufacturer HPLC verification. The Standard Lyophilized grade is third-party purity tested and manufacturer verified. Our Standard (Non-Lyophilized) products are also manufacturer verified and third-party purity tested. All products meet a minimum purity of 98.5%, with the vast majority exceeding 99%. Each designation reflects a specific level of quality control and preparation.
