Synthetic ACTH(4-7) analog, sold for laboratory research.
Identity
Picture snipping four amino acids out of a much longer hormone, ACTH, and adding three more to help the fragment last. That is Semax, a synthetic peptide built by Russian researchers in the 1980s. Most of what is published on it sits in Russian-language clinical and lab journals rather than international trials.
Semax is a synthetic acth(4-7) analog of 7 amino acid residues. SBz Industries sells it for laboratory research.
Research
In plain terms, with a link to every study. The most useful thing to notice is what each study was done in.
Semax has been looked at mostly in Russian clinical studies and in rat experiments from Moscow research institutes. A rat study measured a brain protein called BDNF, and a hospital study followed 110 adults over five months. There is no large trial published outside Russia, and most source papers are in Russian.
rats2006
Researchers gave rats Semax and measured a brain-growth protein called BDNF and its receptor in the hippocampus, the brain region tied to memory. Levels of that protein and receptor activity went up, and the treated rats performed better on a learned avoidance task than untreated rats.
Semax, an analog of ACTH(4-10) with cognitive effects, regulates BDNF and trkB expression in the rat hippocampus.

people2018
A Moscow hospital study followed 110 adults in rehabilitation, comparing those given Semax with those who were not. The team tracked a brain-growth protein in the blood and a standard recovery scale over five months.

Handling
Lyophilized: -20C, protected from light. Reconstituted: 2-8C.
Give the vial twenty minutes on the bench before opening it, so water does not condense onto the powder.
Slowly, down the inside wall of the vial, never straight onto the powder.
Leave it alone until it clears. Do not shake it. Shaking damages the peptide.
Once mixed, it breaks down much faster than the dry powder. Keep it cold and dark.
Documentation
An independent lab tests every compound we sell. It confirms the compound is what the label says and measures purity by HPLC.
The latest certificate is on the product page, so you can read the result before you order.

No. Semax has never been approved as a drug by the FDA. It is sold in Russia as a prescription nasal product but has no equivalent regulatory status in the United States.
Published human studies on Semax are almost all from Russian hospitals and Russian-language journals. Large trials run in other countries have not been published.
Semax ships as a freeze-dried powder. Mix it with bacteriostatic water, added slowly down the inside wall of the vial, and let it dissolve without shaking. The researcher decides the working concentration, not us, and we publish no protocols.
Lyophilized: -20C, protected from light. Reconstituted: 2-8C. Vials ship in plain outer packaging with no product name on the outside.
Yes. An independent lab tests every compound: it confirms the compound is what the label says and measures purity by HPLC. The latest certificate is on the product page, and you can read it before you order.
Researchers and institutions, 21 or over. By ordering you confirm the material is for laboratory research and will not be used in humans or animals.
