Semax (N-Acetyl)

NA Semax (N-Acetyl Semax) – 5mg & 10mg Heptapeptide (Colombia)

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.

Product Overview

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.

Applications in Research

• Neuropeptide and signalling pathway investigation
• Cognition, learning, and memory research models
• Studies involving ACTH-derived peptide chemistry
• Exploration of stress-response and regulatory pathways

Why NA Semax Instead of Standard Semax?

• N-terminal acetylation enhances stability during storage and in solution
• Greater resistance to enzymatic degradation
• More consistent behaviour in multi-use or extended-duration studies
• Now considered the preferred modern form of Semax among advanced research suppliers
