Question 1

What is Selank?

Accepted Answer

Selank is a Russian-developed peptide studied for anxiety relief and mild focus support. It is also called TP-7 and is a synthetic analogue of tuftsin, an immune-related molecule the body makes naturally. Selank is approved in Russia for anxiety disorders and neurasthenia but is not FDA-approved.

Question 2

What is the typical Selank dosage?

Accepted Answer

Subcutaneous research-use protocols use 250-500 mcg per day, usually starting at 250-300 mcg for 1-2 weeks before stepping up. Russian intranasal clinical protocols use 600-2,700 mcg per day, split into 2-3 sprays across a 14-21 day course. Pick one route per cycle and keep the math simple.

Question 3

What is Selank's half-life?

Accepted Answer

The plasma half-life is short — about 2-10 minutes — but the calming and focus-related effects last 12-24 hours. The lasting effect comes from changes in brain chemistry that continue after the molecule itself is cleared. When Selank breaks down, one of its byproducts is tuftsin, which still has biological activity.

Question 4

How is Selank reconstituted?

Accepted Answer

Add bacteriostatic water to the 30 mg lyophilized vial using sterile technique. A 30 mg vial with 6 mL gives 5,000 mcg/mL, which means 0.05 mL (5 units on a U-100 syringe) equals 250 mcg. A 30 mg vial with 10 mL gives 3,000 mcg/mL, so 0.10 mL (10 units) equals 300 mcg. Aim the water at the inside of the vial wall, let it sit 1-2 minutes, then gently roll the vial — never shake.

Question 5

Is Selank a nasal spray?

Accepted Answer

In Russia, Selank is sold as a prescription nasal spray for anxiety disorders. Outside Russia, research-use Selank is most often supplied as a lyophilized powder for either subcutaneous injection or for users who prepare their own intranasal solution. Both routes are described above.

Question 6

Is Selank FDA-approved?

Accepted Answer

No. Selank is not FDA-approved as of June 2026. It has not completed an FDA-style Phase 1-3 development program. It is approved in Russia and has been in clinical use there since the 1990s.

Question 7

What are the most common Selank observed effects?

Accepted Answer

Russian trial reports describe a mild safety profile — no sedation, dependence, tolerance, or withdrawal reported. The most common observed effects are mild injection-site irritation (SubQ), mild nasal stinging or dryness (intranasal), and occasional mild headache during the first few days.

Question 8

How does Selank compare to Semax?

Accepted Answer

Selank is anxiety-first. It works mainly through GABA and serotonin pathways. Semax is focus-first. It works mainly through BDNF and dopamine pathways. They are often paired together as the Russian Nootropic Stack because their profiles complement each other. See the Semax protocol page for full details.

Question 9

Can Selank and Semax be used together?

Accepted Answer

Yes — the combination is called the Russian Nootropic Stack and is one of the most common community pairings. Community protocols typically start at 250 mcg Selank plus 300 mcg Semax per day and titrate each compound independently. There are no published combination clinical trials. See the Russian Nootropic Stack page for stack-specific dosing.

Question 10

What vial sizes does Selank come in?

Accepted Answer

This page now plans around a 30 mg lyophilized Selank vial. One 30 mg vial covers most 4-week and 8-week SubQ planning ranges, while higher-dose 12-week planning may require a second vial.

Question 11

How is reconstituted Selank stored?

Accepted Answer

Store the reconstituted liquid at 35.6-46.4F (2-8C) and protect it from light. Typical stability is about 3-4 weeks. Do not freeze the liquid. Lyophilized (powder) Selank is stored at -4F (-20C) long-term or at 35.6-46.4F (2-8C) short-term.

Question 12

What is the maximum studied Selank dose?

Accepted Answer

Russian intranasal clinical protocols have used up to 2,700 mcg per day, split across 2-3 sprays for up to 21 days. Community subcutaneous protocols typically cap around 500 mcg per day, though some sources discuss up to 1,000 mcg per day. Higher doses are not better and have not been validated in registered trials.

Question 13

Where can I calculate Selank reconstitution and syringe units?

Accepted Answer

Use the PepPal calculator for exact dose-to-unit conversions. Plug in the vial size, BAC water volume, and target dose, and it returns the syringe units for any U-100 syringe.

Question 14

Is this page medical advice?

Accepted Answer

No. This page is an educational research reference. It is not medical advice and is not a treatment plan. Selank is not FDA-approved and is not intended for unsupervised human use. Always work with a qualified clinician before considering any peptide protocol.
