Semax + Selank is a research blend combining two synthetic neuropeptides: Semax (CAS 80714-61-0; heptapeptide Met-Glu-His-Phe-Pro-Gly-Pro, ACTH(4–7)-PGP analogue, proline-stabilised) and Selank (CAS 129954-34-3; heptapeptide Thr-Lys-Pro-Arg-Pro-Gly-Pro, tuftsin analogue). Both are lyophilised at ≥99% purity by HPLC. Each compound has been independently studied in neuroprotection, BDNF signalling, anxiolytic and cognitive models. For laboratory research use only; not for human or veterinary use.
Pairing two of the most studied regulatory neuropeptides to emerge from Russian peptide science, Semax + Selank is a research blend of two short, heptapeptide-class molecules investigated for their effects on the nervous system. Semax is a synthetic analogue of the ACTH(4–10) fragment, while Selank is a synthetic derivative of the immunomodulatory peptide tuftsin — supplied together as a combined preparation for comparative and complementary neuropeptide research.
Two peptides, two regulatory lineages. Semax was developed by modifying the N-terminal region of the adrenocorticotropic hormone fragment ACTH(4–10) and adding a Pro-Gly-Pro tail that confers metabolic stability, yielding a peptide studied for nootropic and neurotrophic-like activity. Selank descends from tuftsin, an endogenous tetrapeptide tied to immune signalling, and is examined largely for anxiolytic-like and neuromodulatory properties. Because the two molecules arise from distinct biological lineages — one neurohormonal, one immunoregulatory — combining them offers researchers a single preparation in which to explore overlapping and divergent peptide actions.
What the research explores. Studies in cellular and animal models have addressed several aspects of the two peptides' biology:
These findings derive from in vitro and animal studies in controlled research settings; they characterise the peptides' biology and do not represent evidence of benefit for any non-investigational application. Full citations are listed under the Scientific References tab.
Physicochemical profile. Appearance: white lyophilized powder · Solubility: soluble in water. (Semax and Selank are distinct heptapeptide-class molecules; see the COA for batch-specific identity data.)
Specification & quality. Each individually sealed vial contains 20 mg of total peptide (Semax 10 mg + Selank 10 mg) as a white lyophilized powder, verified at ≥99% purity by HPLC.

Semax + Selank is a research blend co-formulating two short regulatory neuropeptides — Semax and Selank — in a single vial (10 mg of each, 20 mg total). Both are heptapeptide-class molecules studied for effects on the nervous system. The blend is supplied strictly for laboratory research use only (in vitro) and is not for human or veterinary use, administration or consumption.
Both Semax and Selank are short, stabilised regulatory neuropeptides from the same area of peptide science, and co-formulating them lets researchers study the two together in one preparation. The pairing reflects their shared neuropeptide class, not any consumer rationale. The blend is supplied strictly for laboratory research use only (in vitro), with no human or veterinary application and no dosing guidance.
The blend supplies both peptides co-formulated in one vial (10 mg each), whereas buying them separately gives two standalone vials you reconstitute independently. The blend is convenient for studying them together; separate vials let you control each peptide's preparation independently. All are supplied as synthetic peptides for laboratory research use only (in vitro), not for human or veterinary use.
In total peptide content the blend holds 10 mg of Semax plus 10 mg of Selank, matching the amounts in the standalone vials, but it is a single co-formulated vial reconstituted together rather than two separate vials. The practical difference is preparation, not the listed amounts. The blend is supplied strictly for laboratory research use only (in vitro).
Semax + Selank is a blend of two specific, individually defined neuropeptides, while Cerebrolysin is a single defined mixture of many short peptides and amino acids. One combines two known molecules; the other is an inherently multi-component preparation. Both are studied in neuro research and supplied strictly for laboratory research use only (in vitro), not for human or veterinary use.
For blends, the ≥99% HPLC purity criterion applies per component: each peptide is tested individually, with identity by mass spectrometry and purity by HPLC, and results are documented in the per-batch Certificate of Analysis. Manufacturer documentation is not published, to protect supply-chain integrity. To request the COA, contact info@condorresearch.com. Supplied for laboratory research use only.
Each component is tested individually by an independent third-party laboratory, and the per-batch Certificate of Analysis documents identity and ≥99% HPLC purity for each peptide in the 10 mg + 10 mg formulation. For confirmation of the stated amounts on a specific lot, contact info@condorresearch.com. The blend is supplied strictly for laboratory research use only (in vitro).
The blend is listed as soluble in water, so both peptides are reconstituted together with a single aqueous diluent for analytical laboratory preparation; the vial holds 20 mg total (10 mg + 10 mg). Each component's concentration is derived from its mass and the diluent volume. Any reconstitution data is for in-vitro laboratory use only, never for human or animal use.
Yes. Both Semax and Selank are water-soluble, and the blend is listed as soluble in water, so a single aqueous diluent reconstitutes both components together. This makes one diluent sufficient for the co-formulated vial in laboratory preparation. Any reconstitution data is for analytical laboratory use only, not for human or veterinary use. For details, contact info@condorresearch.com.
Store the unopened vial at -20°C, protected from light (24-month shelf life). After reconstitution, handle the solution as a laboratory working stock kept cold. All storage and preparation guidance is for analytical laboratory use only, never for human or veterinary use, administration or consumption.

Identity by MS confirmed in our facility. Communication around storage and handling was precise and professional.
Reconstitution was clean with no visible particulates. The lot-specific COA matched the assay we ran in-house — purity is exactly as stated.
We verify every incoming compound by HPLC; this batch came back within tolerance of the certificate. Dispatch from the EU warehouse was quick.
Cold-chain handling was respected end to end. Vials arrived sealed, labelled and intact. Documentation is the most thorough I've seen from an EU supplier.
Solubility and stability were as described. Knocked one star only because express shipping options are limited, but quality is not in question.
