Semax: research, prices and suppliers
A synthetic ACTH-derived heptapeptide, approved in Russia for neuroprotection and studied in research on cognition and stress adaptation.
Semax is a heptapeptide derived from the ACTH(4-10) fragment of the stress hormone ACTH, approved as a medication for ischemic stroke in Russia. Research also examines it in relation to neuroplasticity and cognitive function, without activating the cortisol axis.
Facts
- CAS number: 80714-61-0
- Molecular weight: 813.9 g/mol
- Amino acids: 7
- Purity specification: ≥ 98 % (HPLC, commercial standard)
Evidence
- In a rat study, a single intranasal application of semax increased hippocampal BDNF protein levels 1.4-fold and TrkB phosphorylation 1.6-fold. PubMed ID 14556513
- In the same fMRI study with 52 healthy participants, semax also showed altered functional connectivity between the amygdala and temporal cortex, with effects that were in part distinguishable from selank. Panikratova KR et al. 2020, Doklady Biological Sciences, Bd. 490, S. 9-11
Frequently asked questions
Does semax act like a classic nootropic?
Research links semax primarily to neuroprotective and BDNF-related effects, less to an acute focus effect like classic stimulants.
Is semax the same as selank?
No, both are related Russian peptides with different origins. Semax derives from ACTH and is mainly linked to neuroprotection, selank from tuftsin and mainly to anxiety regulation.
Is semax legally available in Germany?
Semax is not approved as a medication in Germany or the EU and is offered exclusively as a research chemical for laboratory purposes, not for human use.

Questions about interpretation
What does the search “Semax protocol” mean?
“Protocol” is often used to mean a regimen. This page explains research and documented listings. It contains no doses, cycles or instructions for human use. An online regimen is not scientifically validated simply because it is widely shared.
Sources and data basis
These references come from the existing dataset. A link alone verifies neither a study claim nor supplier quality. Uncertainty remains explicit where records are undated or incomplete.
