About Semax / Selank
The honest rundown
Straight information, no hype — so your conversation with a physician starts from the truth.
Semax and Selank are peptides with a research history primarily abroad, where they're discussed for focus, stress resilience, and cognitive support. They're paired here as complementary nootropic-style peptides.
U.S. clinical data is limited, and their regulatory status differs from FDA-approved products. A physician decides whether they're appropriate for you and helps keep expectations grounded.
How it works
What the science actually looks at
Semax
Studied abroad for cognitive and focus-related signaling, including effects on neurotrophic factors.
Selank
Discussed for stress resilience and a calm-focus profile in the research where it's been studied.
Limited U.S. data
Most research comes from outside the U.S.; domestic clinical evidence is limited.

Questions
Common questions
Do these actually boost cognition?
The research is mostly international and limited, so we won't claim guaranteed cognitive benefits. A physician helps you weigh what's known against the hype.
Are they FDA-approved?
No — they're compounded and not FDA-approved here, with most research abroad. A licensed physician decides whether they're appropriate for you.
How are they taken?
Typically a subcutaneous injection on a physician-set protocol. Supplies and instructions are included with every order.

Educational information only — not medical advice, and not a claim of results. Whether any therapy is right for you, and at what dose, is determined solely by an independent licensed physician after reviewing your medical history.
How it works at TCO
No therapy is a product you simply buy
An independent licensed physician reviews your history and determines whether therapy is appropriate. Want to talk it through with the doctor directly? We'll set that up.If approved, your order is fulfilled by a state-licensed 503A compounding pharmacy with temperature-controlled shipping and every supply included — and you're coached throughout your journey.
Prescription products require an evaluation with a licensed medical professional, who will determine whether a prescription is appropriate. Compounded medications are prepared by a state-licensed 503A compounding pharmacy and are not FDA-approved; the FDA does not review compounded medications for safety or effectiveness.
TCO Wellness is a wellness and concierge-care company — we do not practice medicine. All prescriptions are issued by independent licensed physicians after review of your medical history, and medications are compounded and dispensed by a state-licensed 503A compounding pharmacy. Individual results vary.
