ACTH(4-10) heptapeptide.
Semax is a synthetic heptapeptide analog of adrenocorticotropic hormone fragment 4-7 (ACTH 4-7), developed at the Institute of Molecular Genetics. Like Selank, it is officially registered as a medicinal product in Russia. Supplied as research-grade material with 3rd-party HPLC verification and full Certificate of Analysis per lot.
Semax is a synthetic heptapeptide analog of adrenocorticotropic hormone fragment 4-7 (ACTH 4-7), developed at the Institute of Molecular Genetics. Like Selank, it is officially registered as a medicinal product in Russia.
Published work describes Semax as upregulating BDNF and NGF expression in the CNS, modulating hippocampal and prefrontal monoamine neurotransmission, and providing neuroprotection in ischemic and stress models. The C-terminal extension blocks rapid enzymatic degradation characteristic of ACTH fragments.
Registered in Russia for cerebrovascular disease, cognitive function, and ischemic stroke. Not FDA-approved. Widely available as a research compound and nootropic.
The above summarizes published research literature. This is not medical advice, a protocol, or a recommendation for use. This compound is supplied for laboratory research only.
Semax is a 7-residue peptide with molecular formula C37H51N9O10S and molecular weight of approximately 813.9 Da.
The full structural data and release specifications are in the Compound Profile section above. Every lot ships with an independently verified Certificate of Analysis.
Each lot is independently verified by a 3rd-party analytical laboratory (STERIS Labs, Alcami Analytical, or equivalent) before release. Release specification is HPLC purity ≥ 99.5% (typical > 99.8%), mass spectrometry identity match within ±0.5 Da, water content < 5.0% Karl Fischer, and endotoxin < 0.25 EU/mL by LAL (USP <85>).

All compounds ship at ambient temperature in discreet, tamper-evident packaging. Lyophilized peptide powder is stable at room temperature for typical transit windows, which is why research-grade vendors ship this way. Tracked; signature not required.
Store unopened lyophilized product at 2–8°C protected from light. Once reconstituted, most peptides are stable at 2–8°C for approximately 28 days (compound-dependent).
Registered in Russia for cerebrovascular disease, cognitive function, and ischemic stroke. Not FDA-approved. Widely available as a research compound and nootropic.
All PeptideBros compounds are sold strictly as chemical reference materials for in-vitro laboratory research. They are not for human consumption.
HPLC-verified. Mass-spec confirmed. Ambient-stable transit. The paperwork other vendors hope you never ask for.
