About Semax

We built the program we wished existed.

Semax exists to make a decades-old, well-studied cognitive peptide available the way it should be — through a licensed provider, from a U.S. compounding pharmacy, with honest claims and lab-verified quality. No gray-market vials, no hype.

If you've ever researched Semax, you already know the problem: a peptide with 30+ years of clinical history and 200+ published studies, sold mostly as unregulated "research chemicals" by sellers who can't tell you what's actually in the bottle. We thought people deserved a better front door.

Why we started

Semax was developed at a Russian national research institute and has been prescribed clinically since 1994. The science is genuinely interesting — it works on dopamine receptor sensitivity and raises BDNF, the growth factor behind learning and new neural circuitry. But in the U.S., access has been a mess: questionable purity, no medical oversight, and marketing that ranges from vague to outright false.

We started Semax to close that gap responsibly. That means a licensed clinician reviews every customer, the product is compounded by a U.S. state-licensed pharmacy, every batch is tested for potency, and we ship cold-chain so the dose on the label is the dose in the bottle. It also means we tell you what the evidence does and doesn't support.

What we stand for

Evidence first, hype never

We cite real literature, name what's still unproven, and never imply Semax treats or cures disease. If a claim can't survive a careful read of the research, it doesn't go on the page.

A clinician in the loop

Every order is reviewed by a licensed provider. You're not buying a "research chemical" off a checkout page — eligibility and dosing are medical decisions made by a professional.

Verified quality

Compounded by a U.S. state-licensed pharmacy, lab-tested for potency and purity, and shipped cold-chain because peptides degrade with heat.

You stay in control

Transparent pricing, no lock-in, pause or cancel anytime, and a 60-day money-back guarantee. We'd rather refund you than argue with you.

How the program works

  1. You take a short eligibility assessment. Two minutes, covering health history and goals.
  2. A licensed provider reviews you. They determine whether the therapy is appropriate and set a personalized protocol — including whether standard Semax or N-Acetyl Semax Amidate fits.
  3. A licensed pharmacy compounds and ships your order. Cold-chain, lab-verified, delivered to your door — no clinic visit, no waiting room.
  4. You have ongoing support. Questions about dosing, side effects, or your protocol go to our care team and, where appropriate, your provider.

Our medical & editorial standards

Health content carries real responsibility. Everything we publish about Semax — mechanisms, dosing, safety, and comparisons — is written to be accurate, sourced, and reviewed against the available evidence. We describe our review process, sourcing, and correction policy on our Medical & Editorial Review page.

Important: Semax is not approved by the U.S. Food and Drug Administration to diagnose, treat, cure, or prevent any disease. Compounded medications are not FDA-approved products. This page is informational and is not medical advice — a licensed provider determines eligibility and appropriate use.

The people behind Semax

Semax is operated by a small team of clinicians, pharmacists, and operators who care about doing this category honestly. Our clinical content is reviewed by licensed medical professionals; our fulfillment is handled in partnership with U.S. state-licensed compounding pharmacies.

Medical Review Board

Licensed U.S. physicians & pharmacists

Reviews clinical claims, dosing guidance, and safety information across the site, and oversees individual eligibility decisions.
