Q: How much bacteriostatic water for 10 mg of Selank?

Adding 2 mL of bacteriostatic water to a 10 mg vial of Selank gives 5 mg/mL: each 10 units on a U-100 insulin syringe holds 500 mcg. With 1 mL it's 10 mg/mL (1,000 mcg per 10 units); with 3 mL, 3.333 mg/mL (333.3 mcg per 10 units). More water makes small amounts easier to measure. Mixing charts: 5 mg, 10 mg, 11 mg, 30 mg.

Q: Does Selank work? What does the research say?

Evidence grade B (some human evidence), from 12 papers: Small Russian randomized trials (62-70 patients) against or added to benzodiazepines, without placebo; most other evidence is from rodents. Selank (a tuftsin analogue) has a few small Russian clinical trials in anxiety disorders comparing it with or adding it to benzodiazepines, without placebo control; most other evidence is from rat and mouse studies. Additional Russian reports (an open-label randomized trial in atopic dermatitis, a binge-eating report with no stated control group, two rodent studies) are consistent with an anxiolytic effect but add no placebo-controlled data. See the papers.

Q: What dose of Selank was used in studies?

Selank is studied in people. adults with generalized anxiety disorder or neurasthenia (randomized comparison with medazepam): not reported in the PubMed abstract not reported in the PubMed abstract; adults with phobic-anxiety and somatoform disorders (comparison with phenazepam): not reported in the PubMed abstract not reported in the PubMed abstract; adults with anxiety-spectrum disorders: phenazepam alone vs phenazepam plus Selank (randomized): not reported in the PubMed abstract not reported in the PubMed abstract. These are amounts used in published studies or official labels, not a recommendation.

Q: Where do people discuss Selank? Is there a Selank Reddit?

Removed from FDA's Category 2 on about April 22, 2026 after its nominations were withdrawn. That doesn't add it to any allowed list, so US pharmacies still can't compound it from bulk ingredient.

Animal studies: Rat studies gave Selank intraperitoneally at about 80-1000 μg/kg per dose (e.g. 100 mcg/kg/day for 20 days).

The Russian clinical trials do not state the Selank dose in their PubMed abstracts, so no human dose is listed here. Doses in animal studies do not translate directly to people. Selank is registered in Russia but not approved by FDA or EMA.

What the research says

Some human evidence

Why: Small Russian randomized trials (62-70 patients) against or added to benzodiazepines, without placebo; most other evidence is from rodents.

Selank (a tuftsin analogue) has a few small Russian clinical trials in anxiety disorders comparing it with or adding it to benzodiazepines, without placebo control; most other evidence is from rat and mouse studies. Additional Russian reports (an open-label randomized trial in atopic dermatitis, a binge-eating report with no stated control group, two rodent studies) are consistent with an anxiolytic effect but add no placebo-controlled data.

Selank: questions people ask

What is Selank?

Tuftsin analog anxiolytic. A seven-amino-acid peptide derived from the immune peptide tuftsin; reduces anxiety in studies without sedation or dependence, given nasally.

How much does Selank cost?

The cheapest Selank from an independently tested vendor is $0.560 per mg (Nantong Guangyuan Chemical GYC, Selank 10 (3010) [US warehouse], $56.00). Across 173 listings from 90 vendors the median is $3.00 per mg.

Where can I buy Selank?

90 vendors tested by Finnrick sell Selank. The cheapest per mg right now: Nantong Guangyuan Chemical GYC ($0.560), Mix Peptides ($0.580), Cartman Gear ($0.600). 28 of them publish a lab report (COA) for Selank; compare lab scores and reports in the table above before buying.

How much bacteriostatic water for 10 mg of Selank?

Adding 2 mL of bacteriostatic water to a 10 mg vial of Selank gives 5 mg/mL: each 10 units on a U-100 insulin syringe holds 500 mcg. With 1 mL it's 10 mg/mL (1,000 mcg per 10 units); with 3 mL, 3.333 mg/mL (333.3 mcg per 10 units). More water makes small amounts easier to measure. Mixing charts: 5 mg, 10 mg, 11 mg, 30 mg.

Is Selank FDA approved?

Approved in Russia as an anti-anxiety drug; not approved in the US.

Can Selank be compounded in the US?

Removed from FDA's Category 2 on about April 22, 2026 after its nominations were withdrawn. That doesn't add it to any allowed list, so US pharmacies still can't compound it from bulk ingredient. Compounding status for every peptide.

Does Selank work? What does the research say?

Evidence grade B (some human evidence), from 12 papers: Small Russian randomized trials (62-70 patients) against or added to benzodiazepines, without placebo; most other evidence is from rodents. Selank (a tuftsin analogue) has a few small Russian clinical trials in anxiety disorders comparing it with or adding it to benzodiazepines, without placebo control; most other evidence is from rat and mouse studies. Additional Russian reports (an open-label randomized trial in atopic dermatitis, a binge-eating report with no stated control group, two rodent studies) are consistent with an anxiolytic effect but add no placebo-controlled data. See the papers.

What dose of Selank was used in studies?

Selank is studied in people. adults with generalized anxiety disorder or neurasthenia (randomized comparison with medazepam): not reported in the PubMed abstract not reported in the PubMed abstract; adults with phobic-anxiety and somatoform disorders (comparison with phenazepam): not reported in the PubMed abstract not reported in the PubMed abstract; adults with anxiety-spectrum disorders: phenazepam alone vs phenazepam plus Selank (randomized): not reported in the PubMed abstract not reported in the PubMed abstract. These are amounts used in published studies or official labels, not a recommendation.

Where do people discuss Selank? Is there a Selank Reddit?

Communities focused on it include r/CognitivePeptides, r/Semax, r/Selank. Experiences shared there aren't evidence, and some allow vendor promotion. All communities.
