Semax 10mg (10 Vials / Kit)

Semax at a glance

Semax is a synthetic heptapeptide with the sequence Met-Glu-His-Phe-Pro-Gly-Pro. Its first four residues match the 4-7 segment of adrenocorticotropic hormone, and the added Pro-Gly-Pro tail slows breakdown by peptidases. It was developed by researchers at the Institute of Molecular Genetics in Moscow. Although it descends from ACTH, it is not treated as a hormonal peptide, because the shortened sequence no longer carries the adrenal-stimulating activity of the parent molecule.

Price and availability

Sold by UWA Biotech and sent from the United States, this listing is a kit of 10 vials at 10mg each (100 mg in total). $95.00 buys the whole kit, which is $0.95/mg. 20 brands sell Semax on GLP1 Forum Escrow, with a typical price of $0.60–$3.30 per mg (median $0.95); this listing is inside that range. Your payment waits in escrow until you confirm the parcel arrived, and only then is it released to the brand.

What it is studied for

Much of the mechanistic literature centers on neurotrophins. Rodent studies report that Semax raises levels of brain-derived neurotrophic factor and its receptor TrkB in the hippocampus and cortex, and gene-expression work after experimental ischemia describes shifts in inflammatory and vascular transcripts. Other papers propose effects on dopamine and serotonin turnover and possible interactions with melanocortin receptors, which would fit its ACTH ancestry. Antioxidant-like activity has also been described. How these observations connect, and which matter most, has not been settled, and the data come chiefly from animal tissue.

Research and regulatory status

Semax holds a different regulatory position from most catalogue peptides. Russian authorities list it as a registered medicine, supplied as nasal drops, and clinical reports from Russia cover stroke and cognitive disorders. Those studies are mostly small and published in Russian-language journals, which limits outside scrutiny. Semax has not been approved by the FDA or the EMA, and in the United States and Europe it is handled as an unapproved research compound with a largely preclinical evidence base.

Checking the lab data

Identity is best confirmed by mass spectrometry showing the mass expected for Met-Glu-His-Phe-Pro-Gly-Pro, with any N-acetyl or amidated variant stated explicitly when a vendor sells a modified form. HPLC purity should come from a chromatogram, not a bare figure. Because the sequence contains methionine, oxidized impurities are a known risk, so a clean main peak matters. Expect a white, intact lyophilized cake and a batch-matched, dated report.

Storage and preparation

Freeze-dried peptide keeps best sealed, cold and dark. Once it has been dissolved, refrigerate it, avoid repeated warming and follow the stability limits in your study protocol.

Concentration arithmetic: one 10 mg vial dissolved in 2 mL gives 5 mg/mL, or 10 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.
