What it is

Semax/Selank Blend combines two synthetic neuropeptides — Semax and Selank — in a single lyophilized research preparation totaling 10 mg. Semax is a synthetic analog of the ACTH(4-10) fragment (Pro-Gly-Pro stabilized, MEHFPGP) studied as a modulator of BDNF and NGF expression and of dopaminergic and serotonergic signaling. Selank is a synthetic heptapeptide analog of the endogenous immunopeptide tuftsin (TKPRPGP) studied for GABAergic and anxiolytic activity and for modulation of monoamine and cytokine pathways. The combined preparation is used to investigate overlapping nootropic, neuroprotective, and neuroregulatory mechanisms in parallel. ≥99% purity (HPLC).

Purity: ≥99% (HPLC)
Form: Sterile lyophilized powder
Total content: 10 mg (Semax + Selank)
Storage: -20°C, protect from light and moisture
Reconstitution: Bacteriostatic water (BAC water) or appropriate buffer
Stability: 24+ months as supplied; reconstituted solutions stored at 2–8°C and used within 30 days

Supplied as a lyophilized powder and sealed against light and moisture — shelf-stable, no cold chain required. Every lot is assayed by an independent laboratory and the certificate is published before the compound is listed. Strictly for in-vitro laboratory research.

Research applications

BDNF and NGF expression and neurotrophic signaling studies (Semax)
Dopaminergic and serotonergic modulation research
GABAergic and anxiolytic pharmacology investigation (Selank)
Tuftsin-analog immune and cytokine modulation studies
Cognitive function, learning, and memory research models
Neuroprotection and stress-response (oxidative and behavioral) studies

Storage & handling

Handle under aseptic conditions in accordance with laboratory safety protocols. Lyophilized material should be stored at -20°C protected from light and moisture. Reconstitute by injecting bacteriostatic water (BAC water) slowly along the vial wall and swirling gently — do not vortex. Once reconstituted, store at 2–8°C and use within 30 days; aliquot to avoid repeated freeze-thaw cycles. Refer to the Certificate of Analysis (CoA) for batch-specific handling recommendations. For laboratory research use only — not for human consumption, veterinary use, or food and drug applications.
