Overview
Semax — ACTH(4–7)-derived heptapeptide
What is Semax?
Semax is a synthetic heptapeptide: the ACTH(4–7) fragment of adrenocorticotropic hormone, extended with the same stabilising Pro-Gly-Pro tail used in Selank. The design keeps the fragment's neuroactive character while removing the parent hormone's endocrine role — and makes the molecule stable enough for practical laboratory use.
Why researchers choose it
Semax is a staple of cognition, neuroprotection, and BDNF-pathway research, with decades of literature behind it. As a melanocortin-derived sequence with no corticotropic activity, it offers a distinctive CNS-focused probe that complements Selank's neuro-immune profile — the two are frequently studied side by side. Supplied as a lyophilized 15 mg vial.
The REPRIME standard
Decades of literature deserve batch-level proof. Every batch is independently HPLC-tested and released at ≥99% main-peak purity, with the batch COA published in the Certificates repository. The 15 mg lyophilized vial ships cold-chain in tamper-evident packaging with a unique REP-XXXX-XXXX-X code — one scan at first use confirms it is genuine. For laboratory and research use only; not for human consumption.
Storage
Store lyophilized at -20°C. After reconstitution, refrigerate at 2-8°C.
