This is plain-language harm-reduction information, not medical advice. Peptides discussed here are research compounds; most are not approved for human use. People will use them either way — we would rather they have the facts.

What it is

Selank is a synthetic analogue of a naturally occurring immune-modulating peptide called tuftsin. It is officially approved in Russia as an anti-anxiety medicine.

It is gentler than benzodiazepines — it tends to dial down anxiety without making you drowsy. Used standalone or paired with semax.

History

Developed at the Russian Academy of Sciences in the 1990s. Approved as a Russian medicine for generalised anxiety disorder in the 2000s.

How it works

Modulates GABA, serotonin and dopamine systems, increases BDNF, and has immune-modulating effects.

Dosage

  • Intranasal: 300–900 mcg per day, split through the day.

How it is taken

  • Intranasal spray, same workflow as semax.

How to reconstitute

  • 5 mg vial with 5 ml BAC water = 1 mg/ml. Each ~100 mcl spray delivers ~100 mcg.

How it should arrive

White powder in sealed vial.

How it should look once reconstituted

Clear colourless solution.

What to expect, and when

  • Calming effect: within 30–60 minutes of dosing.
  • Cumulative mood / anxiety improvements: 1–3 weeks.

Side effects

  • Sneezing or stinging on application.
  • Mild drowsiness in some users (less than benzodiazepines).

Risks

  • Long-term human use within Russia's approved use is reasonably well established.
  • No notable abuse / dependence concerns.

Potential gains

  • Reduced anxiety without significant sedation.
  • Improved stress tolerance.
  • Mild cognitive support.

Other useful information

Pairs well with semax — semax to push focus, selank to keep anxiety down.
