NA-Selank Amidate

In plain English

NA-Selank Amidate is Selank with protective chemical caps on both ends. Users take it for the same calm, clear-headed effect as Selank, and describe it as stronger and longer-lasting.

What it's used for

  • Anxiety and stress
  • Calm focus
  • Sleep support
  • Mood

Benefits

Research on the modified form is limited; its effects are expected to follow Selank, which reduced anxiety in human studies from Russia without sedation or dependence. Users report calm, steady mood and less worry.

How it works

In simple terms: it is Selank protected from breakdown.

Like Selank, it is thought to support GABA signaling, balance serotonin and dopamine, and slow the breakdown of the body’s own calming peptides (enkephalins).

Development history

  • 1990s–2000s: Selank developed in Russia.
  • 2010s: Acetylated and amidated versions appear among users.

The total amount printed on the vial label.

2Bacteriostatic water added

More water makes each dose a bigger, easier-to-measure draw. It does not change how much peptide is in the vial.

3Dose per injection

Use the dose from your protocol or your clinician. 1 mg = 1,000 mcg.

4Your syringe

All three are U-100 insulin syringes: 100 units = 1 mL. Smaller barrels make small doses easier to read.
