Summary

What is Selank?

Selank is a synthetic peptide of seven amino acids. It's based on tuftsin, a natural fragment from the immune system, with three extra amino acids that make it more stable. It was developed in Russia.

What is it researched for?

It's studied for anxiety, stress and focus.

How does it work?

In studies it influences enkephalins, calming substances the body makes, and genes linked to GABA, the brain's main system for slowing down activity.

Preparation

3 mLof bacteriostatic water
for the 10 mg vial

If you already know how to reconstitute, that's all you need.

ConcentrationOn a U-100 syringe3.33 mg per mL30 units = 1 mg

Reconstituting means mixing the powder in the vial with bacteriostatic water to get a solution that's ready to use. The peptide comes as a powder because it keeps better that way.

How to reconstitute

The same 6 steps as the video. Tap an image to see it full size.

1. What you need. Have everything on the “What you need” list at hand.
2. Get ready. Wash your hands well and work on a clean surface. Let the vial and the water reach room temperature.
3. Clean the stoppers. Remove the plastic caps. Wipe the stoppers with alcohol and let them dry.
4. Draw the water. Draw 3 mL of bacteriostatic water. Read the measurement at the plunger edge closest to the needle.
5. Add the water slowly. The vial is vacuum sealed and pulls the water in: hold the plunger right where it enters the syringe. Let the water run down the inside wall of the vial, never straight onto the powder. Dispose of the needle in a rigid container.
6. Dissolve completely. Don't shake the vial. Swirl it gently or let it rest; it usually takes 30 seconds to 3 minutes. It's ready when there are no particles and it's completely clear.

Afterward: label the vial with the date you reconstituted it and keep it in the fridge (see Storage).

Reading the amounts

mg · amount of peptide

mL · volume of liquid

mg/mL · resulting concentration

Storage

Once reconstituted, it needs cold and darkness.

2 °C – 8 °C

Always in the fridge. Take it out only to draw your dose and put it back right away.

Never freeze it

Once reconstituted, freezing damages it. Also avoid the fridge door, where the temperature changes the most.

4 to 6 weeks

Use it within that time after reconstituting. Protect it from light: keep it in its box or a dark container.

Before reconstitution: it keeps best in the fridge or freezer, away from light and moisture.

If you travel: carry it in an insulated bag with a cold pack, without direct contact with the ice.

Dosing and calendar

Once a day, always at the same time

This is a suggested progression, not a cycle you have to finish: 4 weeks on and 2 off. Go up each week only if you feel good; you can stay on any dose.

After week 4, take 2 weeks off before repeating. Don't go over 900 mcg a day.

Practical tips

About the dose

Judge it by the week

Write down how you feel every day; that way you compare weeks, not single moments.

Stick to the maximum

Don't go over 900 mcg a day. If you feel good on less, stay there.

If side effects show up

Headache, restlessness or insomnia

Go back to the previous dose, or take a day or two off and restart with less.

At the injection site

Rotate between belly and thighs, and leave a few inches between one injection and the next.

Frequently asked questions

Why injected and not nasal?

In Russia it's sold as nasal drops, and that's how the studies used it. We offer it for subcutaneous injection, the way many people in forums use it: with an insulin syringe the dose is measured precisely.

Can it be combined with Semax?

It's a popular combination: Selank is studied for anxiety and Semax for focus. There are no studies of the two together.

Does it make you sleepy?

Studies and forums describe it as calming without drowsiness.

Where can I check the lab results before I buy?

In Quality, on this same page, you can open the report for the strength and lot we sell.

What's included, and how much is shipping?

Every peptide vial comes with one 3 mL vial of bacteriostatic water, plus alcohol wipes; the reconstitution guide is on this page. Shipping is free anywhere in Colombia, in discreet packaging.

When will my order ship?

If your payment is confirmed before 4 p.m. (Monday to Friday) or noon (Saturday), we ship it that same day. After that time, and on Sundays and Colombian holidays, we ship it the next business day. Bogotá time.

What payment methods can I use?

Cards, PSE, Nequi, Daviplata and Bancolombia through Wompi, or USDT on the TRC-20 network. You'll see every option at checkout.

What do the studies say?

There are human studies, almost all in Russia and with nasal drops.

Anxiety

2008 · 62 adults with generalized anxiety or neurasthenia

The effect on anxiety was similar to that of medazepam, a reference medicine, and Selank also reduced fatigue.

See the study · PubMed ↗

Anxiety

2014 · 60 adults

It showed a marked anti-anxiety effect that lasted a week after the last dose, and it improved quality of life.

See the study · PubMed ↗

How to read this data

The studies are small and almost all from the same country.
They used nasal drops, not injections.
The studies used their own preparations, not KAILAB vials.
