Semax

Semax for sale in 30mg research vials

Semax for sale at Peptide Partners is supplied as lyophilized (freeze-dried) powder in 30mg vials, intended for laboratory research. The vials are packed in sets of 2, 5 or 10, so a single order holds 60mg, 150mg or 300mg of material. It belongs to our small neuropeptide group and ships from a US storefront alongside the rest of our tested research peptides. Every vial in a pack is drawn from the same lot, so a series of experiments can run on one documented batch from the first vial to the last.

What is the Semax peptide?

Semax is a synthetic heptapeptide with the sequence Met-Glu-His-Phe-Pro-Gly-Pro. The first four residues match the 4–7 fragment of adrenocorticotropic hormone (ACTH); the Pro-Gly-Pro tail was added by its Russian developers to make the short chain more resistant to enzymatic breakdown. Because of that origin, the literature often files it as an ACTH(4–10) analogue, even though it no longer carries the hormone’s full sequence. Published work on the semax peptide sits mainly in neuroscience. Rodent and cell-culture studies have measured markers such as brain-derived neurotrophic factor (BDNF) expression after exposure to the peptide. Those papers describe what researchers observed in models, and nothing on this page should be read as a claim about people. Researchers comparing short regulatory peptides often study Semax next to Selank, which shares the same Pro-Gly-Pro extension on a different parent sequence. The shared tail makes the pair a natural comparison when the question is how the parent sequence changes behaviour in a model.

Semax price and pack sizes

• 2 vials × 30mg = 60mg pack
• 5 vials × 30mg = 150mg pack
• 10 vials × 30mg = 300mg pack

The Semax price per mg falls as the pack size rises, which makes the 300mg pack the lowest-cost way to buy Semax by weight; live pack prices are shown above. The 60mg pack suits a pilot run, while the 150mg and 300mg packs cover longer projects that need a single lot throughout.

Semax FAQ

What is Semax?

Semax is a synthetic seven-residue peptide, Met-Glu-His-Phe-Pro-Gly-Pro. Its first four amino acids come from the 4–7 region of ACTH, and a Pro-Gly-Pro tail was added to slow enzymatic breakdown. Peptide Partners supplies it as lyophilized powder in 30mg vials for laboratory research use only.

How much is Semax?

Semax is sold in packs of 2, 5 or 10 vials, giving 60mg, 150mg or 300mg in total. Current pack prices are printed live on the product page, and the cost per mg is lowest on the 300mg pack because the price per mg drops as the pack size rises.

Is Semax the same as Selank?

No. Both are synthetic heptapeptides developed in Russia and both end in Pro-Gly-Pro, but Semax is built on an ACTH fragment while Selank is built on tuftsin, a short immunoglobulin-derived sequence. They are separate molecules with separate listings and separate lot records.

How is each Semax lot tested?

Every lot goes to independent third-party testing, and the current Semax lot has passed endotoxin, heavy-metal and purity screening. The results for your batch appear in the specification table and the Certificates tab, and the certificate ledger can be searched by the batch ID printed on the vial label.

Where can I buy Semax in the USA?

You can order it directly from this page on the Peptide Partners US storefront. Payment is by CashApp, Apple Pay, Chime or cryptocurrency, free-shipping eligibility is worked out in the cart, and an order can be cancelled for a full refund at any point before it ships.
