Review
My batch of semax was tested for endotoxins and passed. it was also of high purity, and identified by hplc-ms. FTIR analysis was also done, I couldn't find any peaks from cresols, TFA, Acetonitrile, or other alcohols, however some of the relevant frequencies were not included in the FTIR section. I'd assume the lab would mention it if any were found. Testing was done through BTlabs, so i assume the vendor sent it through finnrick for analysis.
