SELANK.
Selank. A 7-amino acid synthetic analog of tuftsin that modulates GABA, serotonin, and enkephalin signaling simultaneously. Anxiolytic without sedation. Calm without compromise.
*Clinician-prescribed. Ships from a licensed U.S. pharmacy.
The mechanism
Anxiety Is a Signal Problem. Not a Willpower Problem.
Anxiety is a measurable disruption in excitatory-inhibitory balance. When GABAergic tone is insufficient, excitatory signaling dominates: the amygdala becomes hyperreactive, prefrontal control weakens, and the stress axis fires disproportionately. Benzodiazepines address this by forcing GABA-A activation. It works but causes sedation, amnesia, and dependence. The mechanism is blunt.
Selank modulates the same system differently. It alters transcription of genes encoding GABA receptor subunits, transporters, and ion channels, with 45 neurotransmission genes shifting within hours. Simultaneously it preserves enkephalins and suppresses pro-inflammatory cytokines. Three systems from one peptide: GABAergic modulation for calm, enkephalin preservation for resilience, and immune regulation for the inflammatory substrate sustaining chronic anxiety.

Safety
What to expect+
Selank has demonstrated an exceptional safety profile across nearly two decades of clinical use in Russia. Side effects are rare and mild: transient injection site irritation and occasional fatigue during initial days. No sedation, no amnesia, no impaired coordination, no dependence, no tolerance, no withdrawal.
Frequently asked
What is SELANK?+
Selank is a synthetic heptapeptide developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It extends tuftsin, a naturally occurring peptide from human IgG, with a stabilizing tripeptide so it resists enzymatic breakdown. It's studied for calm and focus, bridging the immune and nervous systems.
How does SELANK work?+
It modulates GABA signaling and helps normalize serotonin and dopamine activity, while also supporting BDNF and preserving the body's stress-buffering enkephalins. Importantly, it isn't a benzodiazepine and doesn't force inhibitory signaling. Instead it adjusts the brain's inhibitory architecture at the gene-expression level, aiming for calm without sedation.
What can I expect from SELANK?+
Many people find Selank supports a calm, focused state without the sedation or fog associated with conventional options. Reported effects include steadier composure and, for some, a mild lift in energy and focus, though that's not guaranteed. Results vary, so your experience may differ from someone else's.
Are there any side effects?+
Selank has a strong safety record from nearly two decades of clinical use in Russia. Side effects are rare and mild, mainly transient injection site irritation and occasional fatigue in the early days. Users report that they don't notice sedation, amnesia, impaired coordination, dependence, tolerance, or withdrawal.
How is SELANK made and shipped?+
It starts with a short online medical intake, and if it's a fit, a licensed U.S. provider writes the prescription. From there it's compounded at a licensed 503A pharmacy and batch tested by a third party for sterility and potency. Then it's shipped cold-packed right to your door.
What's the best way to buy SELANK?+
You've got two options. You can buy a one-time single vial, or you can go with the Build Your Stack subscription, which lets you mix and match the compounds in your monthly stack, starting at $189 per month. For ongoing use the stack is the better value, and you can pause, skip, or cancel anytime.
