Focus & Sleep
The focus & sleep category covers reference peptides studied in vitro across neuro-modulation, cognitive-signalling and sleep-architecture research — including Semax, Selank, DSIP and Epithalon. Each compound is provided as a lyophilized reference standard with ≥99% HPLC purity, LC-MS identity confirmation and an independent batch analysis. Peptide Cyprus supplies these materials to laboratories and qualified researchers for in-vitro use only; they are not medicines and are not for human or animal consumption.
