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. 98.5% vs. 99% Purity: Both grades are manufactured in our US-based facility and tested for quality at a third party lab. While the 99%+ purity grade is our highest reference grade product line, the 98.5% purity variants still exceed US pharmaceutical standards.
