Full shipping informationResearch-grade Semax + Selank Blend. A multi-peptide blend has no single purity figure; selected lots independently tested. Lyophilized powder in sealed glass vial. For research purposes only. Not for human consumption.
Semax + Selank Blend combines two Russian-developed nootropic peptides with different but complementary mechanisms in a single vial (10mg each, 20mg total). Both were developed by the Institute of Molecular Genetics of the Russian Academy of Sciences and have an unusually long research history in Russia and Eastern Europe — a distinction that provides some pharmacology data, even if that literature predates modern trial standards.
Semax is a synthetic heptapeptide derived from the ACTH(4-7) sequence (methionine-glutamate-histidine-phenylalanine) with a proline-glycine-proline extension that increases its stability and bioactivity. In research models it is studied for its role in BDNF and NGF pathways — upregulating brain-derived and nerve growth factors. Research effects include neuroprotection, acetylcholinergic and neuropeptidergic receptor binding in memory consolidation models, and attention-related parameters. Semax has been studied in models of ischemic injury, which provides some translational context, though the evidence base is not equivalent to Western Phase III trial standards.
Selank is derived from tuftsin, an endogenous immunoregulatory peptide. In research models it is studied for its interaction with the GABA system, including a GABA-B receptor component. Selank has also been studied for immunomodulatory activity, including stress-induced immune suppression in animal models.
The combination addresses both acetylcholinergic and neuropeptidergic receptor binding (Semax) and GABA-system and immunomodulatory signalling (Selank) — complementary rather than redundant mechanisms in the context of cognitive performance research.
| Parameter | Value |
|---|---|
| Component 1 | Semax 10mg (ACTH(4-7) derivative) |
| Component 2 | Selank 10mg (Tuftsin analogue) |
| Total per Vial | 20mg combined |
| Purity | No single figure (multi-peptide blend) |
| Format | Lyophilized powder, single-use vial |
| Storage | -20°C before reconstitution; 2-8°C after |
Store at -20°C before reconstitution. Refrigerate at 2-8°C after reconstitution. No blend-specific use window is published once mixed. Both peptides are stable under proper conditions but should be protected from light and heat.
Semax is derived from the ACTH(4-7) sequence — the minimal active fragment of adrenocorticotropic hormone — modified for stability. Its primary documented mechanisms in research models involve upregulation of BDNF and NGF, neurotrophins that support neuronal survival, plasticity, and function. In rodent models it enhances learning, memory consolidation, and attention-related parameters. It also has documented neuroprotective effects in ischemia models, which is an active area of preclinical research.
Selank is studied in rodent models for its interaction with the GABA system, including GABA-B components, and for its immunomodulatory activity.
Semax and Selank are supplied together as a lyophilized blend in a single vial, for reconstitution in laboratory research only.
Semax + Selank Blend is supplied for research purposes only. Not for human use. Handle in compliance with institutional biosafety guidelines.

Researcher Confidence
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 →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.
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.
