Selank dose guide

A peptide dosage chart, one peptide at a time: its dose range, how often it’s taken, a typical run and the units on your syringe. All 69 peptides in the PepVault library.

A community reference, not medical advice. Each range is what has been studied or is commonly run, never a dose for you.

Selank dosage

A synthetic peptide based on tuftsin, an immune molecule your spleen naturally produces. In small Russian trials it eased anxiety about as well as benzodiazepine comparators, and no dependence has been reported, though it hasn't been formally studied. In rats it modulated GABA receptors and raised BDNF (a brain growth factor). Commonly reported: calmer and less socially tense without feeling sedated, subtle effects for some, and mild tiredness at higher doses. Approved as an anxiety medication in Russia.

Dose range
250–500 mcg (research range). Studied in research — not a recommendation.
How often
Daily
A typical run
10–21 days. 2–4 week cycles typical. Can repeat with breaks. Tolerance generally low.
How it’s taken
Nasal spray: Nasal spray, SubQ injection
Evidence
Moderate: Animal studies + some human data

~10 min in blood; nasal effect longer

Selank on your syringe

With a 5 mg vial and 2 mL of water (2.5 mg in every mL), on a 0.3 mL (30-unit) U-100 insulin syringe: the low end, 250 mcg, is 10 units; and the high end, 500 mcg, is 20 units. 20 doses in the vial at the low end. All U-100: 100 units to the mL. A U-40 syringe reads differently.
