Description
Structure & Identity
The kit pairs two structurally distinct heptapeptides that happen to share a chain length and nothing else. Semax is a seven-amino-acid ACTH(4-7) analog (Met-Glu-His-Phe-Pro-Gly-Pro, CAS 80714-61-0), while Selank is a seven-amino-acid tuftsin analog (Thr-Lys-Pro-Arg-Pro-Gly-Pro, CAS 129954-34-3), built from an entirely unrelated parent sequence. Each retains its own backbone and ships in its own vial, so the two sequences can be handled as per your assay/study design.
Research Background
The kit brings together two CNS-research threads.
- Semax neuro-signaling. Semax is studied for BDNF/NGF-related signaling [PMID: 24661604].
- Semax protein-level research. Protein-profile work characterizes its signaling in a CNS model [PMID: 34201112].
- Selank signaling. Selank is studied for GABA and monoamine signaling [PMID: 30255741].
- Selank BDNF research. Linked to BDNF changes in a rat model [PMID: 31625062].
- Complementary study. BDNF/NGF signaling (Semax) alongside GABA/monoamine signaling (Selank).
These are research contexts, not approved uses, and the kit is intended for laboratory study.

Storage & Handling
Keep both sealed vials frozen at -20°C and shielded from light until use. After preparing for your assay, store each solution at 2-8°C and use it in your study within about two weeks. Warm a vial to room temperature before opening, and avoid repeated freeze-thaw cycles so each peptide stays intact.
Quality Assurance
Both peptides in the kit are produced under research-grade manufacturing controls and verified by an independent lab before release. Purity is measured by reverse-phase HPLC and identity by mass spectrometry, with testing carried out by third-party laboratories, including Janoshik Analytical and domestic US labs. Each vial ships with its own batch-specific certificate of analysis.
Frequently Asked Questions
What is in the BALANCE Kit?
Two separate vials: Semax 10 mg and Selank 10 mg, both short CNS-research peptides. The kit is supplied for research use only.
Why are Semax and Selank paired?
They complement each other in research: Semax is studied for BDNF/NGF signaling, Selank for GABA/monoamine signaling. Together they cover two sides of CNS-signaling research.
How are Semax and Selank different?
Semax is an ACTH(4-7) analog linked to BDNF/NGF signaling; Selank is a tuftsin analog linked to GABA and monoamine signaling. Different origins, different research focuses.
Are the two peptides combined in one vial?
No. Each comes in its own separate vial, so researchers can reconstitute and study each independently.
Is this kit FDA approved?
No. Neither peptide is FDA approved in the US, though both are approved medicines in Russia. The kit is a research-use-only preparation, not for human or veterinary use.
Does each vial come with its own COA?
Yes. Each peptide is tested separately and batch-specific certificate of analysis is available on product page and COA library.
How should the kit be stored?
Keep both powders frozen at -20°C and protected from light until use. As with all lyophilized peptides supplied for research, preparation and post-preparation handling should follow your lab’s protocols.
How are the peptides verified?
Each is tested to ≥99% purity by reverse-phase HPLC with mass-spec identity confirmation by an independent lab.
