Focus, sleep & calm peptides, explained
A small group of peptides is studied for effects on attention, anxiety-related behaviour and sleep — mostly in research outside the United States. This page explains that context honestly.

What people are usually asking
The questions here are about concentration, stress, and sleep that will not settle. They are also questions where the first-line answers — sleep hygiene, screening for depression or anxiety, thyroid and iron, medication review — are far better established than anything on this page. A good provider starts there.
Selank and Semax were developed in Russia and have a clinical history there but no FDA review. DSIP (delta-sleep-inducing peptide) has an older research literature with mixed results.

Read the page →Where the evidence stands
Semax and Selank have been used clinically in Russia and have published studies, but the trial quality varies and none has been reviewed by the FDA. DSIP was studied in the 1970s–90s with inconsistent findings on sleep. For all three, long-term safety data in the populations asking about them is limited.

Questions worth bringing to a provider
The intake is where individual questions belong. These are the ones that tend to make that conversation useful.
- Have the common causes been checked — thyroid, iron, sleep apnoea, depression, medication side effects?
- Would you want a sleep study or a mental-health assessment before discussing anything here?
- How would this interact with medication I already take?
- What is the quality of the evidence, and where was it produced?
What happens if you start an intake
The intake asks about sleep patterns, mood, medications (including anything for anxiety, ADHD or sleep), and substance use. A licensed provider reviews it and will often point first toward evaluation of the underlying cause. Free, about 10 minutes, no obligation.
Frequently asked questions
Are Selank and Semax legal in the US?
They are not FDA-approved and are not available as prescription drugs in the United States. Any discussion here is educational; legality of possession and use varies and is a question for a provider and your jurisdiction.
Will the intake diagnose anxiety or ADHD?
No. The intake is a screening questionnaire reviewed by a provider. A diagnosis requires a proper clinical assessment, which the provider may recommend.
Is there dosing information on this site?
No. Vitrex never publishes dosing for any peptide.
