Description
About Semax
Semax (CAS: 80714-61-0) is a synthetic heptapeptide derived from the ACTH(4-7) fragment (Met-Glu-His-Phe) with an appended Pro-Gly-Pro tripeptide sequence to enhance metabolic stability. Developed at the Institute of Molecular Genetics of the Russian Academy of Sciences, Semax retains the neurotrophic properties of the parent ACTH fragment while resisting rapid enzymatic degradation.
Mechanism of Action
Semax influences multiple neurotransmitter systems and neurotrophic pathways. It has been shown to upregulate brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) expression in experimental models. The peptide modulates dopaminergic, serotonergic, and cholinergic neurotransmission. Research also indicates effects on gene expression patterns related to neuronal survival and plasticity, involving activation of signaling cascades including the MAPK/ERK pathway.

Why researchers choose CertaPeptides
Who actually tests this?
Selected lots are independently verified by Janoshik Analytical (Czech Republic) and published on the Janoshik public portal. Other lots ship with the supplier's batch specification. See /coa for the published wall.
View COAs →What if I get the wrong batch?
Every vial label carries a code. Look it up on our Verify page: it shows what CertaPeptides publishes for that code and, for a withdrawn lot, that the lot was withdrawn and why. If yours is withdrawn, or if the code on your label finds nothing, email us that code.
View COAs →Where does it ship from?
Romania (EU). We are CERTALAB SRL, CUI 54169956, VAT-registered. Sameday for Romania, GLS for most EU destinations, TCE Worldwide for the remaining cross-border EU and non-EU markets (UK, Switzerland). Delivery 1–15 business days depending on destination — exact window shown at checkout.
Shipping details →What if there's a problem?
You have a 14-day withdrawal right under OUG 34/2014 (Romanian/EU consumer law), with escalation to ANPC and alternative dispute resolution (SAL) available. Contact us at support@chinapeptideshop.com.
Returns policy →Product Information
This product is intended for scientific research and development purposes only. It is a chemical substance that shall not be used as a drug, medicine, active substance, or ingredient in any product intended for human or animal consumption. Researchers must handle this compound in accordance with their institutional biosafety guidelines. Use only in properly equipped laboratory settings with appropriate personal protective equipment.
Peptides in lyophilized (freeze-dried) form are shipped in sealed glass vials using standard delivery methods and do not require refrigeration during transit. Lyophilized peptides are highly stable at ambient temperatures for the duration of standard shipping (typical transit windows are shown at checkout). Once received, transfer the product to refrigerated storage (2–8°C) promptly.
Frequently Asked
Research peptides are supplied in lyophilized (freeze-dried) form. The amount of material is typically only a few milligrams — appearing as a very thin film or small pellet at the bottom of the vial, often nearly invisible. This is completely normal.
Unlike some suppliers who add bulk fillers (such as Mannitol), CertaPeptides provides pure peptide without unnecessary additives.
