What is Semax?
Russian-developed heptapeptide analog of ACTH(4-10). Used as a prescription nootropic in Russia for stroke recovery and cognitive enhancement.
Experts on background and overview · 2 cited mentions
"The other versions that are different from Semax, they're they're modified basically. They require a lower dose and less frequent injections or administrations. So, whether you do the nasal spray or the injections, I think Adamax or the other versions you can do once per day."
"Starting Semax. Good starting dose daily - 500 micrograms. Whether that's intranasally or subQ. Unless it's N-acetyl Semax or N-acetyl Semax amidate, those dosages are a little bit lower because it seems to be more bioavailable."
How does Semax work?
Upregulates BDNF expression in hippocampus/cortex. Also modulates dopaminergic and serotonergic systems.
Mechanism note
These mechanisms are presented as research observations and hypotheses from the indexed data, not as confirmation of clinical effect in humans.
Experts on mechanism · 2 cited mentions
"Increasing brain-derived neurotrophic factor. So Semax and Selank, Adamax seems to be stronger than Semax. Both in the same category. They're both increasing BDNF."
"Semax and Selank in the same way that they're both increasing BDNF."
What is Semax researched for?
Increases BDNF (brain-derived neurotrophic factor), sharpens focus, improves mood, reduces anxiety-driven cognitive suppression. Tanner pairs it with Selank.
Experts on uses and effects · 2 cited mentions
"Will reported that Semax may support neurological energy - describing it as helping with 'brain energy' (SZszWyKnYTQ)."
"Probably just Dhexa and Semax. If you wanted the extreme, then cerebrolysin is worth considering."

| Speaker | Source | Timestamp | Protocol | Evidence |
|---|---|---|---|---|
| Vigorous Steve | Ozempic Issues, Injectable Anadrol, Shrink Gyno, Hypo On Tren, PIP... | 01:38:44 | Steve reported using 500 mcg/day intranasal or SubQ for regular Semax; he found lower doses sufficient for N-acetyl Semax formulations due to increased bioavailability. | anecdotal |
| Vigorous Steve | Pool Party Protocols, 16-Week Tren Cycle, No GH Bloat, EQ Safety,... | 00:43:45 | Semax: twice per day (nasal spray or injection) due to rapid metabolism. Modified analogs (Adamax/N-acetyl Semax) → once per day at lower dose. | anecdotal |
| Tanner Tattered | Tanner Tattered: Peptides & Drugs for Long-term Bodybuilding Success | 00:53:19 | Intranasal spray, daily. Often stacked with Selank. Adamax = combined Semax+Selank formulation. | anecdotal |
| Vigorous Steve / Steve | Prevent Insulin Resistance On High-Dose GH, Mirabegron Vs. Clen Vs.... | 00:23:39 | 500 mcg intranasal Semax in the morning after a Cerebrolysin course (per Vigorous Steve) | anecdotal |
| Vigorous Steve | 9-Me-BC For MAXIMUM Dopamine Libido & Motivation | Managing Libido &... | 00:51:28 | ~1 month cycle stacked with Selank | anecdotal |
| The Biohacking Specialist | I Injected the Real World Limitless Peptides to See If They Work | 00:13:25 | Users report administering one to two drops per nostril with head tilted slightly back, allowing absorption rather than drainage into the throat. Common reported protocols involve running for 2-4 weeks followed by 2-4 weeks off. Users report that a single morning dose is sufficient and that afternoon redosing is typically avoided. | anecdotal |
| Boost Your Biology (Lucas Aoun) | Stop Taking Peptides Until You Hear This! | 00:07:26 | Intranasal delivery; Speaker 1 reported typical doses of 200 to 900 micrograms per day in divided doses. | anecdotal |
| Trensparent with Nyle Nayga | Togi Says Young Men Should Do Drugs. I Disagree. | 00:47:41 | Injectable route: pins one extra CC of Semax/Semaxan; frequency not stated. | anecdotal |
