Description
The Selank Semax blend from Certified Peptides holds 10mg Selank and 10mg Semax, freeze-dried together in one vial. It’s made in the USA and sold for laboratory research only.
What’s in the Selank Semax blend?
Selank is a seven-amino-acid peptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) based on tuftsin, with a Pro-Gly-Pro tail added. It was developed at the Institute of Molecular Genetics in Moscow.
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.
Semax and Selank both come from the Institute of Molecular Genetics in Moscow and are often studied side by side. Semax is linked to BDNF and memory work in rodents, Selank to anxiety through the GABA system.
The ratio is fixed at 10mg/10mg. Because everything is freeze-dried together, the ratio can’t drift the way it can when you mix separate vials. One reconstitution, one label, the same proportions in every draw.
How the Selank Semax blend works
Selank is based on tuftsin, a short immune peptide cut from antibodies. The Pro-Gly-Pro tail added at the end makes it more stable.
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.

Selank Semax blend research
Russian studies report anxiolytic effects in rats and changes in GABA-related gene expression.
A small Russian trial compared it with medazepam in generalized anxiety.
Dolotov and colleagues reported that Semax raised BDNF and its receptor TrkB in rat hippocampus.
Russian clinical studies looked at stroke recovery.

How to reconstitute Selank Semax blend
Here’s the math for 20mg of powder:
- 1mL of bacteriostatic water gives 20mg/mL
- 2mL of bacteriostatic water gives 10mg/mL
- 3mL of bacteriostatic water gives 6.67mg/mL
Choose the volume that suits your measurements. Mark the vial with the concentration and date so nobody has to guess later. The vial itself holds 3mL, so that’s the upper limit.
Use sterile bacteriostatic water, like our 10mL bacteriostatic water. Let the vial reach room temperature, run the water slowly down the inside of the glass, then roll the vial gently until the powder dissolves. Don’t shake it. Shaking can shear peptide chains.
How to store Selank Semax blend
The dry powder keeps best cold. A freezer at -20°C is ideal for long-term storage, and a fridge works for a few weeks. After reconstitution, store it in the fridge and finish it within roughly four weeks.
A 6 vial container keeps open and sealed vials upright and apart, which makes the fridge a lot easier to manage. For a bigger collection, the Big Everything Box holds vials and supplies in one latching case.
Selank Semax blend purity and lab testing
Every batch of Selank Semax blend is made in the USA and checked by an independent U.S. lab for three things: that it’s the right compound, that the amount matches the label and that purity is 99% or better by HPLC.
You don’t have to take our word for it. The certificate of analysis for the current batch is in the image gallery at the top of this page, next to the product photo, and it shows the test date and the results.
Purity isn’t the whole story, so batches are screened for endotoxins, heavy metals and sterility too. Write the batch number from the label into your notes so you can match results to the paperwork later.

Selank Semax blend questions
How much is in the Selank Semax blend vial?
10mg of Selank and 10mg of Semax, freeze-dried together. The amount is printed on the label.
Where is it made?
In the USA. We only sell U.S.-made research products, and each batch is tested by a U.S. lab.
Is there a certificate of analysis for Selank Semax blend?
Yes. The current batch’s COA is in the image gallery on this page.
What do I mix Selank Semax blend with?
Sterile bacteriostatic water is the usual choice. The reconstitution section above shows the concentration for each volume.
How should I store it?
Keep sealed vials in the freezer for long-term storage or the fridge for a few weeks. Once mixed, refrigerate and use within about 28 days.
