Description
Every Semax 10mg vial at Prime Peptides holds 10mg of Semax, packed as freeze-dried powder. In short, it’s an ACTH(4-10) analog peptide. It’s sold for laboratory research only.
What is Semax?
Semax is a seven-amino-acid peptide (Met-Glu-His-Phe-Pro-Gly-Pro) based on a fragment of ACTH, with a Pro-Gly-Pro tail added for stability. It was developed at the Institute of Molecular Genetics in Moscow.
It’s registered in Russia and used there as a nasal drop.
The mechanism behind Semax
Semax is based on ACTH(4-10), a piece of the stress hormone ACTH that affects the brain but not the adrenal glands. The Pro-Gly-Pro tail slows its breakdown.
In rats it raised BDNF, a growth factor that supports neuron survival and learning, and changed dopamine and serotonin activity. It’s usually studied as an intranasal compound.

Checking the quality of Semax 10mg
Each Semax 10mg vial arrives with the Prime label, which names the compound and marks it as lyophilized powder for research only. Your order confirmation lists every vial, which makes it easy to match vials to the study they belong to.
If your lab wants independent confirmation, two tests answer different questions. HPLC shows what share of the sample is the main compound, and mass spectrometry confirms that compound has the expected molecular weight.
Keep one study on vials from one order where you can, and log the order number with your data. It removes one variable.
Semax 10mg mixing guide
Working out the strength of your solution takes one division: 10mg over the millilitres you add. Typical volumes give these results:
- 1mL of diluent gives 10mg per mL
- 2mL of diluent gives 5mg per mL
- 3mL of diluent gives 3.333mg per mL
Let the vial reach room temperature, swab the stopper with alcohol and let the diluent run slowly down the inside of the glass. Swirl gently until the solution is clear. Shaking creates foam and can damage the peptide. Prime stocks bacteriostatic water for exactly this step.
Keeping Semax 10mg fresh
Unopened the compound keeps best at -20°C. A fridge is fine if you’ll use it soon. After reconstitution it belongs at 2 to 8°C, and most protocols use it up within 28 days.
Let a frozen vial warm up before opening it, since cold glass pulls moisture out of the air.
