NA Semax (N-Acetyl Semax) is an acetylated analogue of Semax designed to improve molecular stability, resistance to enzymatic degradation, and consistency during repeated laboratory handling. Derived from the ACTH(4–10) fragment, NA Semax preserves the core heptapeptide structure while introducing N-terminal acetylation to enhance structural integrity during storage, reconstitution, and extended research workflows. Poly Biotech offers NA Semax in both 5mg and 10mg formats with immediate availability in Colombia.
Semax originates from the ACTH(4–10) sequence and has been widely used in neuropeptide, cognition, and signalling research models. NA Semax applies an N-acetyl modification to the native sequence, improving its chemical durability and making it the preferred format for long-term or high-frequency peptide studies. As more international labs transition from standard Semax to NA Semax, Colombian research programs can now adopt the updated analogue through local Poly Biotech supply.
NA Semax may be reconstituted with bacteriostatic water or another suitable sterile laboratory diluent according to each laboratory’s internal protocols. Working concentrations, dilution volumes, and handling procedures should follow the specific SOPs established by the research team.
NA Semax 5mg and 10mg vials are available in small and large quantities for laboratories and clinics across Colombia. Poly Biotech can coordinate recurring shipments and integrate NA Semax into broader peptide procurement plans for ongoing research projects.

All Poly Biotech peptides are produced using a lyophilization (freeze-drying) process that guarantees product stability during shipping and storage. This process removes moisture under controlled low-pressure conditions, creating a stable white powder that preserves the peptide’s structure and potency.
