Selank

Description

Selank is a tuftsin analog peptide, and Pure Rawz sells it as freeze-dried vials, a nasal spray and sublingual tablets. Each batch is checked for 99%+ purity. It’s intended for research use only.

Selank explained

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.

It’s registered in Russia for anxiety.

How it acts in research models

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.

In rat studies it changed the expression of genes tied to GABA signaling and raised BDNF. It’s also studied for effects on the enzymes that break down enkephalins, the body’s own opioid peptides.

What studies say about Selank

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.

Selank sizes and forms

There are 6 ways to buy it, from $19.47 to $139.99:

• Peptide, 5mg: $19.47
• Peptide, 10mg: $34.99
• Peptide, 20mg: $59.99
• Nasal Spray, 200mcg per spray/20mg: $79.99
• Nasal Spray, 400mcg per spray/40mg: $139.99
• Sublingual Tablets, 200mcg per tablet/100ct/20mg: $89.99

The vials hold a freeze-dried (lyophilized) powder under a sealed stopper. Freeze-drying keeps the peptide stable in transit. You add sterile bacteriostatic water to dissolve it before use.

The nasal spray is pre-mixed in a metered pump bottle. The label gives the amount per spray and the total, which makes the math simple.

Sublingual tablets are pressed to dissolve under the tongue. Each one holds a fixed amount, printed in the size option, so there’s no measuring.

How labs use it

Cognition studies often test a compound in a deficit model, for example after sleep loss, stress or a drug that impairs memory, because effects are easier to see there than in healthy animals.

Start with the smallest size to confirm solubility and handling, then scale up once the protocol is set.

Test a range of amounts if you can. Many cognition compounds have an inverted-U response, where too much works worse than a moderate amount.

Mixing and concentration

For the 5mg vial, the concentration depends on the volume of water:

• 1mL of bacteriostatic water gives 5mg/mL
• 2mL of bacteriostatic water gives 2.5mg/mL
• 3mL of bacteriostatic water gives 1.67mg/mL

Let the vial reach room temperature, run the water slowly down the glass, and swirl gently until it’s clear. Don’t shake it.

Purity and batch testing

Every batch is tested before it goes on sale. Identity is checked by mass spectrometry, and purity by HPLC, with a target of 99% or higher.

Each container is labeled with the product, the amount and the batch number. Email us that number and we’ll send the certificate of analysis for your batch.

Keeping it fresh

Keep sealed vials in a freezer at -20°C or a fridge at 2 to 8°C, away from light. After mixing, store the vial in the fridge and use it within about four weeks. Keep nasal spray bottles in the fridge once opened, capped and upright.

Store capsules, tablets and powder in a cool, dry place out of direct light, with the lid closed tight.

Note the batch number and the date you opened it in your lab records.

Working with it safely

Handle it the way you’d handle any research chemical: gloves, eye protection and a clean bench. Don’t eat or drink where you work with it.

Keep it out of reach of anyone who isn’t trained, and dispose of used syringes, vials and wipes according to your lab’s waste rules.

Before you start

• Bacteriostatic Water for reconstitution, or Sterile Water if you’ll use the whole vial at once
• sterile insulin-type syringes or pipettes for measuring
• alcohol swabs for the vial stopper

Common questions about Selank

Is Selank in stock?

Yes. It’s in stock and ships from our warehouse after your order clears.

Does it come with a certificate of analysis?

Yes. Every batch is tested, and we’ll email the certificate of analysis for your batch number on request.

Can it be used in people or animals?

No. It’s sold for laboratory research only and isn’t approved for human or veterinary use.

What do I mix it with?

Most labs use sterile bacteriostatic water. Add it slowly down the side of the vial and swirl gently until the powder dissolves. Don’t shake it.

How should I store it?

Follow the storage section above. In short: cold and dark for freeze-dried vials, room temperature and dry for capsules, tablets, powders and liquids, unless the label says otherwise.
