Selank / Semax

Selank / Semax is a research blend that combines two short synthetic peptides originally derived from endogenous regulatory molecules and studied within the nootropic and neuropeptide literature. Selank is a synthetic analog related to the immunomodulatory peptide tuftsin, while Semax is a fragment-derived analog associated with the ACTH/melanocortin family. Offered together as a combined preparation, the blend is positioned within the Cognitive and Longevity category and is provided strictly for laboratory research and professional reference use. It is not approved by the FDA for therapeutic use and is not intended to diagnose, treat, cure, or prevent any condition.

This catalog entry is intended as a professional reference for licensed practitioners ordering wholesale. All descriptions of activity reflect findings reported in preclinical and exploratory research literature rather than established clinical outcomes, and individual results vary.

• Investigated in preclinical literature for its relationship to neuropeptide signaling and neurotrophic pathways
• Studied in research models for markers associated with cognitive performance, attention, and memory consolidation (individual results vary)
• Examined in exploratory research for stress-response and anxiety-related behavioral endpoints (individual results vary)
• Reported in research contexts for interactions with neurotransmitter and neuroimmune systems
• Explored in the nootropic and longevity literature for proposed neuroprotective and adaptogenic activity (individual results vary)

Supplied as a lyophilized powder for research handling. As a general reference, lyophilized peptide is typically reconstituted with bacteriostatic water (or another suitable sterile diluent) added slowly against the vial wall and gently swirled rather than shaken until fully dissolved. Unreconstituted vials are generally stored frozen or refrigerated and kept sealed; once reconstituted, the solution is commonly kept refrigerated, protected from light and excess heat, and used within a limited window per standard peptide-handling practice. Avoid repeated freeze-thaw cycles and maintain aseptic technique throughout. This information is provided for storage and handling reference only and does not constitute dosing guidance; all clinical protocols, dosing, and administration decisions are determined solely by the licensed ordering provider, and this is reference information, not medical advice.

A per-lot Certificate of Analysis, HPLC purity profile, and mass-spectrometry verification are available on request for this product. Ask your account manager for the current lot documentation.

In the published research literature, the two components are proposed to act through complementary central pathways. Semax is studied as a melanocortin/ACTH-fragment analog reported in preclinical work to influence expression of neurotrophic factors such as BDNF and to modulate dopaminergic and serotonergic signaling, which has been of interest in models of neuroprotection and cognitive function. Selank, as a tuftsin-related peptide, has been investigated for proposed modulation of GABAergic and monoaminergic activity and for neuroimmune effects associated with anxiety-related and stress-response endpoints. Combined, the blend is studied for potential additive or overlapping effects on these neuromodulatory systems. These mechanisms remain investigational, are drawn from preclinical and exploratory data, and individual results vary.
