About Semax.

What it is
Peptide derived from ACTH, without hormonal action, researched in relation to nerve tissue.
What you get
A sealed vial with the batch number of the lab report on your label. Bacteriostatic water and needles come along if you tick them.
How to prepare it
Dissolve the powder with bacteriostatic water. The calculator below tells you how much.

Semax is derived from a fragment of ACTH, but lacks the hormonal action of the original molecule. It was developed in Russia and researched extensively there.

The literature looks at the effect on BDNF, a growth factor for nerve cells, and at attention and memory processes in animal models.

Supplied as freeze-dried powder, 10 mg per vial.

Calculate reconstitution

How much bacteriostatic water to add to reach a given concentration.

Add

2,00 mL bacteriostatic water

At this concentration 1 mg equals 20 units on an insulin syringe of 100 units per mL.

This only converts a dilution. It is not dosing advice for humans or animals, and it says nothing about what a suitable amount would be.

How to prepare your vial

Ready in 6 steps .

  1. 1

    Let everything reach room temperature

    Take the vial and the bacteriostatic water out of the fridge and let them sit for fifteen minutes.

  2. 2

    Clean the stoppers

    Wipe the rubber stopper of the vial and of the water bottle with a disinfectant wipe.

  3. 3

    Draw up the water

    Use the calculator to work out how much water you need and draw up exactly that amount.

  4. 4

    Let it run down the glass wall

    Pierce the stopper and let the water run slowly down the inside of the glass, not straight onto the powder.

  5. 5

    Swirl, do not shake

    Gently swirl the vial until the solution is clear. Shaking can damage the peptide.

  6. 6

    Keep refrigerated

    After dissolving with bacteriostatic water, keep the vial refrigerated and use it within the recommended period.

Questions, answered.

Where do I find the report of my batch?
The batch number is on the label of your vial. Every batch is independently analysed for identity, purity and heavy metals. The report belongs to the batch number on your label and can be looked up per batch.
How fast will my order arrive?
Ordered and paid, and your parcel goes to the carrier within 24 hours, Monday to Saturday. Netherlands, with PostNL, 1 to 2 working days. Belgium, with Bpost, 1 to 2 working days. Rest of Europe, with DHL or FedEx, 3 to 8 working days. From € 150,00 we ship for free.
How do I store this?
Store freeze-dried vials at minus 20 degrees, protected from light. After dissolving with bacteriostatic water, keep the vial refrigerated and use it within the recommended period. Avoid repeated freezing and thawing after reconstitution.
Why is it shipped with dry ice?
Everything is packed in the Netherlands and shipped with dry ice, so the contents stay at temperature on the way. On arrival, take the vial out of the packaging and store it straight away according to the storage instructions.
What is the Reload Pen?

What if my parcel does not arrive?
If a parcel does not arrive, we ship again free of charge. If the carrier has registered it as delivered, we first request proof from the carrier.
