What is Semax + Selank?
(synthetic ACTH analog + tuftsine analog)
Semax is a synthetic analog of ACTH (adrenocorticotropic hormone) studied as a nootropic for focus and mental endurance. Selank is a synthetic analog of tuftsine, an immune peptide with anxiolytic (anti-anxiety) effects. Both are given as intranasal sprays or subcutaneous injections. Widely used in Russia and Eastern Europe; growing clinical interest in the West, but US trials are limited.

- SelankStudied for calm and stress
Russian/Eastern European
extensive use and research; Western clinical trials limited
Semax and Selank are prescribed off-label. Semax has human data from Russian studies; Selank evidence is solid in anxiety models. Your physician weighs the geographic evidence gap.
Is it right for you?
Who it's for
Adults who want support for focus and calm during demanding periods.
What sets it apart
Two peptides from Russian medicine, where they are used as nasal drops: Semax for attention, Selank for anxiety.

How neuro peptides work
Day 1
A US-licensed physician reviews your sleep, mood, or cognitive goals, health history, and current medications. Discusses how these early-stage peptides work and the evidence gaps.
1Week 1
Start with a subcutaneous injection or intranasal spray at bedtime (or as directed). Most people find the routine comfortable within days.
2Weeks 2–4
Sleep quality, mood, or focus may begin to shift. Some notice changes within days; others take 3–4 weeks. Keep a sleep or mood journal.
3Month 2
Your physician checks in, reviews your journal, and adjusts dose if needed. Discuss any changes in sleep, mood, energy, or focus.
4Beyond
Neuro peptides work best with consistent use. Your physician monitors your response every 4–6 weeks and adjusts as your needs change.

The science of neuro peptides
Semax enhances cerebral blood flow, dopamine signaling, and cognitive performance in Russian trials. Selank reduces anxiety and supports mood via anxiolytic peptide pathways.
Western clinical data are limited but growing. Your physician uses these based on the extensive evidence from Eastern European research and emerging US interest. Close monitoring during the first month helps establish your response.
Learn moreImportant safety information and common side effects
Neuro peptides are prescribed off-label based on preclinical and early clinical evidence. Common mild effects include injection-site reactions, headache, or temporary sleep changes in the first week. DSIP, Semax, and Selank are not prescribed during pregnancy or breastfeeding, or with active psychiatric medication without careful discussion—some combinations require monitoring or dose adjustment. Tell your physician about every medication, supplement, and any history of seizures or psychosis. Stop and seek care for severe headache, agitation, mood changes that interfere with daily life, or signs of allergic reaction.

Frequently asked questions
How do I use Semax / Selank?
Injected under the skin, 5 days a week, in the morning. The starting prescription is 20 units (0.2 mg) each time. Your physician sets your own dose and it is printed on your label.
What exactly is in it?
Semax, Selank.
How much arrives in each shipment?
1 vial at the starting strength, shipped to your door from a licensed US pharmacy.
Why are these from Eastern Europe, not the US?
Semax and Selank were developed and extensively studied in Russia and Eastern Europe starting in the 1990s. They have decades of clinical use there. Western research and FDA trials are far newer. Your physician weighs the geographic evidence when deciding if these fit your goals.
Why are these off-label?
Off-label means not FDA-approved for these uses, but prescribed by physicians based on preclinical research and clinical experience. It is common in medical practice, especially for emerging therapies. Your physician explains what is known and what remains uncertain.
Can I combine these with other medications?
Tell your physician about every medication, especially psychiatric drugs (SSRIs, antipsychotics), stimulants, or sleep aids. Some combinations need careful timing, dose adjustment, or extra monitoring. Do not start or stop any other medications without discussing with your physician.
What if I don't notice a change?
Some people respond quickly; others take 4–8 weeks. Keep a detailed sleep or mood journal to spot subtle changes. If no response after 6–8 weeks, your physician may adjust the dose, try a different peptide, or explore other options.
Are these safe long-term?
Long-term safety data are limited because human use is recent. Your physician monitors you regularly and reassesses the plan every 3–6 months. If any concerning symptoms arise, stop immediately and report them.
