Semax & Selank
Compounded Intranasal or Injectable — Provider-Directed Dosing Protocol
Semax and Selank are synthetic neuropeptides that have been studied for their roles in cognitive function and stress response modulation. Semax, derived from the ACTH sequence, has been studied for nootropic and neuroprotective properties. Selank, derived from the immunomodulatory peptide Tuftsin, has been studied for anxiolytic and mood-modulating effects. Treatment decisions are made by licensed providers following a clinical evaluation.

Start My Evaluation →The neuropeptide mechanisms — how researchers are studying them
Semax and Selank work through distinct but complementary neurological pathways — studied together for their combined cognitive and stress-response effects.
Semax is a heptapeptide analog of ACTH (adrenocorticotropic hormone). Research has examined its role in BDNF (brain-derived neurotrophic factor) regulation and its potential neuroprotective properties. It holds registered pharmaceutical status in Russia for cognitive applications.
Selank is derived from the immunomodulatory peptide Tuftsin, with added stabilizing amino acids. Research has examined its role in GABA-A receptor modulation and its potential anxiolytic effects on stress response and mood regulation.
Both peptides have been studied for neuroprotective properties. Research has examined their potential role in supporting neurological function and their involvement in neurotrophic factor regulation.
Semax and Selank have been studied in published research, including clinical studies conducted in Russia where they hold registered pharmaceutical status. Treatment decisions in the US are made by licensed providers based on individual health evaluations.
How it works
From your first inquiry to an active treatment plan — here’s the process.
Answer a short health questionnaire. Takes under 5 minutes. Fully HIPAA-compliant. Your provider uses this to evaluate candidacy.
A licensed provider reviews your health profile and determines whether this treatment is appropriate for your individual situation — usually same day.

Questions? Our support team is available 7 days a week. Treatment program participants get priority response.
Quality Control
Every API tested 5 ways before it touches a vial.
The active pharmaceutical ingredients in your medication are tested at the API level — before compounding — across five independent quality markers.
Confirms you’re getting exactly the dose on the label. No underdosed vials.
Zero microbial contamination. Required for anything injected into the body.
Tests for bacterial byproducts that cause dangerous inflammatory responses.
Ensures the compound is stable and safe at the correct physiological pH.
Verifies there are no foreign substances, degradants, or unknown compounds present.
Member experiences.
Verified participants sharing their experience with the process and their provider-directed program.
“My provider took the time to understand my specific cognitive health goals before designing the protocol. The published research was what brought me here — the provider quality is what kept me. Professional, thorough, responsive.”
“I have a neuroscience background and came in with specific questions about the BDNF and GABA-A research. My provider engaged with every one of them clinically. FDA-registered pharmacy, real intake review — this platform is the real thing.”
“Kit arrived in two days. Provider-issued protocol card was specific to my intake, not a generic handout. Support team responded quickly when I had a question about timing. Everything as described.”
What to expect
Every protocol works on its own timeline. Your provider will set expectations specific to your prescription.
Body begins responding. Provider sets starting dose based on your individual health profile.
Provider monitors response and may adjust based on individual tolerance and clinical status.
Provider reassesses the protocol based on your progress and any changes in health status.
Treatment continuation is determined by your licensed provider based on ongoing clinical evaluation.
Before you begin
A few things to know so you’re set up for a safe, provider-guided experience.
Administer only as directed by your provider. Your provider instructions will include guidance specific to your protocol — do not deviate from the prescribed schedule.
Store your vials refrigerated (36–46°F). Do not freeze. Keep out of direct light. Follow any specific storage instructions included with your kit.
Never mix with other medications in the same syringe. If you experience unexpected side effects, hold your dose and contact your provider before continuing.
Contact your provider or our support team before adjusting your protocol. Never self-escalate dosing without provider authorization.
Individual responses vary. Your provider will set timeline expectations specific to your prescription and health profile. Results are not guaranteed.
Your dosage is determined by your provider after reviewing your intake. You will not know your starting dose until after provider approval.

✓ Verified PurchaseI’m on a few medications and my provider reviewed each one for interactions before approving. That clinical rigor is exactly what I needed. Have had no issues and support has been consistently responsive.
✓ Verified PurchaseHad some mild fatigue the first week that my provider attributed to the adjustment phase. They adjusted my protocol slightly and it resolved. The responsiveness of the provider team made it a non-issue.
