Description
Structure & Identity
The kit contains two distinct peptides. Semax is a seven-amino-acid ACTH(4-7) analog, Met-Glu-His-Phe-Pro-Gly-Pro (CAS 80714-61-0). Selank is a seven-amino-acid tuftsin analog, Thr-Lys-Pro-Arg-Pro-Gly-Pro (CAS 129954-34-3). Each keeps its own structure and is supplied in its own vial.
Research Background
The kit brings together two CNS-research threads.
- Semax neuro-signaling. Semax is studied for BDNF/NGF-related signaling and neuroprotection [PMID: 24661604].
- Semax protein-level research. Protein-profile work confirms its ischemia effects [PMID: 34201112].
- Selank anxiolytic mechanism. 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. Cognition-and-neuroprotection (Semax) alongside stress-and-anxiety (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 reconstitution, store each solution at 2-8°C and use it 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 cognition and neuroprotection, Selank for stress and anxiety signaling. Together they cover two sides of CNS 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 the BALANCE 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.
How should the kit be stored?
Keep both powders frozen at -20°C and protected from light. Once reconstituted for research, store each solution at 2-8°C and use within about two weeks.
How are the peptides verified?
Each is tested to ≥99% purity by reverse-phase HPLC with mass-spec identity confirmation by an independent lab.
