Selank
Also known as: TP-7, N-Acetyl Selank Amidate (modified form)
Quick summary
A synthetic seven-amino-acid peptide built from the immune peptide tuftsin with a short stabilizing tail added. Research focus: anxiety-related behavior in rodents, stress models and GABAergic modulation. This page leads with SRP's low-and-slow starting dose.

Amino acid sequence (one-letter code): TKPRPGP
Overview
A synthetic seven-amino-acid peptide built from the immune peptide tuftsin with a short stabilizing tail added. It was developed in Russia, and most papers study it in rodent models of anxiety and stress.

Mechanism
A stabilized analog of tuftsin. Studies suggest it affects GABAergic signaling and the breakdown of enkephalins.
Research areas
- anxiety-related behavior in rodents
- stress models
- GABAergic modulation
Storage & reconstitution
Typically supplied as a lyophilized powder; keep sealed vials cold (refrigerated short term, frozen for long-term holding) and away from light. Laboratories commonly reconstitute with bacteriostatic or sterile water, swirling gently rather than shaking, and keep the solution refrigerated, using it within a few weeks.
Recommended starting dose (low and slow)
| Starting dose | Subcutaneous example starts at 250-300 mcg once daily for weeks 1-2; starts at 200 mcg; at 250 mcg. |
|---|---|
| Frequency | Reported schedules: daily; Daily; Daily. |
| Reconstitution | Examples: 5 mg vial + 2 mL bacteriostatic water = 2.5 mg/mL; 10 mg vial + 2 mL water = 5 mg/mL; 5mg vial + 2mL diluent (as listed). storage note: Reconstituted: refrigerate, used within 4 weeks. |
Studied higher doses
Studies have used doses up to the amounts below. Higher doses can be dangerous. Whether a person can reach them safely depends on height, weight, activity level, training and pre-existing conditions. We recommend following the lower starting dose above, and contacting SRP with any questions.
| Highest amount reported in studies | Conflict: stop at 500 mcg per day, headline range at 750 mcg, nasal course goes to 2,700 mcg/day. Injectable and nasal amounts are not interchangeable. |
|---|---|
| Step-up schedules reported | Subcutaneous example: 250-300 mcg daily weeks 1-2, 400-500 mcg weeks 3-4, then a 4-week break and a repeat at 300-500 mcg. For the nasal form it describes a 14-21 day course split into 2-3 sprays, then a 1-3 week break. |
