Usage Instructions & Safety Notice

This product is a research/cosmetic raw material, not a finished pharmaceutical product. It requires proper reconstitution using sterile water or bacteriostatic water before use. Selank is typically administered via subcutaneous or intranasal route. Unlike traditional anxiolytics, Selank does not cause sedation, memory impairment, or physical dependence. However, first-time users should start with a lower dose to assess individual response. Not for use by pregnant or nursing women.

What Is Selank (SK5)?

Selank is a synthetic nootropic peptide originally developed at the Institute of Molecular Genetics in Russia. It is a heptapeptide (seven amino acids long) that works by modulating the activity of the immune system and influencing key neurotransmitters involved in anxiety and mood regulation, particularly serotonin and dopamine. Unlike benzodiazepines or other anti-anxiety medications that work by sedating the central nervous system, Selank produces a calm, focused state without any drowsiness, memory loss, or risk of addiction. It has also been shown to enhance learning and memory formation, making it a true nootropic – a substance that improves cognitive function while reducing anxiety. SK5 is our high-purity version (99%+), vailable in both 5 mg and 10 mg vials.

Why Choose Selank (SK5)?

Anxiety relief without drowsiness. Most anti-anxiety medications make you feel tired, slow, or foggy. Selank is different. It calms your mind without sedating your body, so you can stay sharp, focused, and productive while feeling at ease.

No addiction or withdrawal. Traditional anxiety medications like benzodiazepines carry serious risks of dependency and painful withdrawal. Selank has no known addiction potential, making it a safer choice for long-term use.

Boosts memory and learning. Selank is not just an anti-anxiety peptide – it is a cognitive enhancer. Users report better focus, improved memory retention, and faster learning. This makes it popular among students, professionals, and anyone who wants to perform at their best.

Supports immune health. Selank has been shown to modulate the immune system, helping the body respond more effectively to stress and illness. This added benefit sets it apart from other nootropics.

Two vial sizes available. Whether you need a 5 mg vial for short-term protocols or a 10 mg vial for extended use, we have both options. Choose the size that fits your needs and budget.
