This product takes the form of white lyophilized powder, with HPLC-tested purity reaching no less than 99%. Each batch comes with full supporting documents including COA and HPLC chromatograms for quality verification.

Solubility: It dissolves readily in sterile water and bacteriostatic water. Storage instructions: The sealed lyophilized powder should be preserved at -20°C in a dry and dark environment; short-term storage at 2-8°C is acceptable. Once reconstituted, store the peptide solution at 2-8°C and use it promptly. Avoid repeated freeze-thaw cycles, as they compromise the peptide’s bioactivity.
