Semax-Selank Blend 20mg

Semax-Selank Blend 20mg combines two synthetic heptapeptides, Semax (ACTH 4-7 PGP) and Selank (a tuftsin analog), at 10mg each in a single 20mg research vial. Both components are HPLC-verified (Semax 99.3%, Selank 99.4%) and every order is independently tested by Renew Labs, a third-party analytical lab, with a batch-specific Certificate of Analysis (COA) included. For laboratory and research use only. Not for human consumption.

Research Applications

Semax is a synthetic analog of the ACTH(4-10) fragment, built from ACTH(4-7) extended with a Pro-Gly-Pro sequence, and is studied for its effects on brain-derived neurotrophic factor (BDNF) and neuroprotection in ischemia models. Selank is a synthetic analog of the immunomodulatory tetrapeptide tuftsin, studied in anxiety, stress, and memory models. The combination supports dual-pathway research across cognitive, stress, and immune signaling.

Purity and Verification

Every batch of Kynetide Semax-Selank Blend is independently tested by Renew Labs. In this batch, Semax is verified at 99.3% and Selank at 99.4% HPLC purity, both exceeding the NLT 98.0% specification. The full analytical panel covers HPLC, ESI mass spectrometry, assay content, Karl Fischer water analysis, bacterial endotoxin testing, and residual solvents (ICH Q3C), supporting reliable, reproducible research results.

Frequently Asked Questions

What is the Semax-Selank Blend?
It is a single 20mg research vial containing 10mg of Semax (ACTH 4-7 PGP) and 10mg of Selank (a tuftsin analog), both synthetic heptapeptides.

What are Semax and Selank studied for?
Semax is studied for BDNF expression and neuroprotection; Selank is studied in anxiety, stress, and memory models. Together they support dual-pathway cognitive and stress research.

What are the CAS numbers and molecular formulas?
Semax: CAS 80714-61-0, C37H51N9O10S, 813.9 g/mol. Selank: CAS 129954-34-3, C33H57N11O9, 751.9 g/mol.

What purity is this batch?
Batch SSC-20102601 is verified at 99.3% (Semax) and 99.4% (Selank) HPLC purity, exceeding the NLT 98.0% specification, with mass spectrometry, endotoxin, water content, and residual solvent testing on the COA.

How does the blend compare to buying Semax and Selank separately?
The blend supplies both peptides in one vial at a fixed 1:1 ratio (10mg each), with separate HPLC purity results for each component on the batch COA.

How should the Semax-Selank Blend be stored?
Store lyophilized material at 2-8°C short term; for long-term storage the batch COA specifies below -20°C, protected from light and moisture.

What documentation comes with each order?
Each order includes a batch-specific third-party COA showing HPLC purity, mass spectrum, assay content, water content, endotoxin, and residual solvent results.
