Product overview
Generic Peptides Semax - 2 and 5 mg Research Vials
Generic Peptides Semax is a synthetic heptapeptide modeled on the ACTH 4-10 fragment, supplied as a lyophilized research powder in 2 mg and 5 mg vials. Its sequence is Met-Glu-His-Phe-Pro-Gly-Pro, a short chain derived from the first part of adrenocorticotropic hormone but without the hormone's steroid-driving end. It was registered as a medicine in Russia in 1994 and is handled as a research chemical elsewhere, which is why it is studied beside the tuftsin analog Selank in central-nervous-system work.

- Lyophilized powder
- GMP-made, HPLC-verified, COA
Variant Comparison
Both vials hold the same heptapeptide; only the amount of powder differs.
| Variant | Dosage | Form and quantity | Best use |
|---|---|---|---|
| Semax 2 mg | 2 mg | Vial | Short |
| Semax 5 mg | 5 mg | Vial | Extended |
The 5 mg vial holds two and a half times the powder of the 2 mg vial and suits longer sampling runs, and the 5 mg size is also the one that carries a U.S. domestic option. For sleep-architecture work the neuropeptide DSIP is a common companion, and the pineal peptide Epitalon is often studied in the same setting.
How Semax Works
The heptapeptide MEHFPGP has the formula C37H51N9O10S, a mass of 813.93 g/mol, the CAS number 80714-61-0 and the PubChem identifier 122178. Published descriptions propose an interaction with melanocortin receptors and a rise in BDNF and its TrkB receptor, most of it recorded in animal and cell models. A Russian clinical report describes better functional and motor recovery after stroke, but the human pharmacology is thin and no human half-life has been established.
Reconstitution & Storage
Add bacteriostatic water down the wall of the vial and swirl, do not shake. Divide the milligrams on the vial by the millilitres added to read mg per mL: a 2 mg vial with 2 mL gives 1 mg/mL, so 0.1 mL on a U-100 syringe reads 100 mcg. Keep the sealed powder at 2-8 C or -20 C, and the mixed solution at 2-8 C for about four weeks without freezing.
Dosage & Administration
No human dose is stated here and the vial is not a medicine in this market. Semax was registered in Russia in 1994 but has never been approved by the FDA or the EMA, so nothing on this page is a treatment protocol or a dosing guide.
For laboratory research only, not for human or veterinary use. Information provided is for educational purposes only and does not constitute medical advice. Consult a qualified healthcare professional before use. Semax is supplied as a lyophilized powder and stays stable when the vial is kept cold and dry.

FAQ
Before you ask
Questions, answered
Semax is a synthetic heptapeptide with the sequence Met-Glu-His-Phe-Pro-Gly-Pro, built from the ACTH 4-10 fragment of adrenocorticotropic hormone. It has the formula C37H51N9O10S, a mass of 813.93 g/mol, the CAS number 80714-61-0 and the PubChem identifier 122178. It was registered as a medicine in Russia in 1994 and has no approval from the FDA or the EMA.
It holds a Russian registration from 1994 and is not approved in the United States or the European Union, so outside Russia it is supplied as a research material. That registration is a national decision and does not transfer to other regulators. The vial on this page is therefore a laboratory product, not a licensed medicine in those markets.
Published descriptions propose an interaction with melanocortin receptors and a rise in BDNF and its TrkB receptor, the signaling pair involved in neuron growth and survival. Most of that evidence comes from animal and cell models rather than from controlled human trials. A Russian clinical report notes better functional and motor recovery after stroke, but the human data remain limited.
Reported problems are mostly mild. Descriptions mention nasal mucosal irritation when the peptide is given by the nasal route, headache, and restlessness or trouble sleeping when it is taken later in the day. Injection-site reactions are common to the subcutaneous route. Long-term safety data do not exist, so nothing beyond short research courses has been documented.
Add bacteriostatic water down the side of the vial and swirl, do not shake. Divide the milligrams on the vial by the millilitres added to read mg per mL: a 2 mg vial with 2 mL gives 1 mg/mL, so 0.1 mL on a U-100 syringe reads 100 mcg, while a 5 mg vial with 2 mL gives 2.5 mg/mL. Keep the powder at 2-8 C or -20 C.
The compound is not named on the WADA Prohibited List and no separate anti-doping entry for it was found. That is absence of data rather than a clearance, and an athlete under anti-doping rules should not read an unlisted research peptide as permitted. The list is revised regularly, so the current edition is the only authority.
Both vial sizes are listed on this page as research material, with international checkout and a U.S. domestic option on the 5 mg vial. International shipping runs about 35 dollars with a transit window of four to ten days, the domestic route runs about 25 dollars over two to five days, and orders are handled within one to two business days. Stock and prices are shown in the options above.
