About this compound
Questions researchers ask
Yes. Both peptides are supplied as a white or almost white powder according to their Certificates of Analysis. The analytical documentation also confirms that both compounds are water-soluble and conform to their respective specifications.
The Selank Semax Peptide Stack includes two high-purity peptides verified by HPLC analysis. Selank demonstrates 99.5% peptide purity, while Semax demonstrates 98.5% peptide purity, with both meeting their established analytical specifications.
Selank is identified by the IUPAC condensed sequence H-Thr-Lys-Pro-Arg-Pro-Gly-Pro-OH. Semax is identified by the sequence H-Met-Glu-His-Phe-Pro-Gly-Pro-OH. These sequences define the amino acid composition and structural identity of each peptide.
Yes. The Selank Semax Peptide Stack includes separate batch-specific Certificates of Analysis for both peptides. Each COA provides analytical information, including batch number, production date, molecular characteristics, purity results, impurity profiles, and storage conditions.
The peptides are characterized using multiple analytical methods documented in their Certificates of Analysis. HPLC analysis is used to evaluate peptide purity and impurity profiles, while additional analytical testing is performed to assess physicochemical characteristics, including water content.
