Reconstitution

Pen format? Pens are supplied pre-mixed and ready for research use — no reconstitution required. The steps below apply to lyophilized vials only.

Swab both vial stoppers with alcohol and allow to dry.
Draw the required volume of bacteriostatic water with a sterile syringe.
Add the water slowly down the inside wall of the vial — never directly onto the powder.
Swirl gently until fully dissolved. Never shake.
Confirm the solution is clear and particle-free.
Label with date and concentration, then refrigerate at 2–8 °C.

Storage & Handling

Lyophilized vials: refrigerate sealed at 2–8 °C away from light; freeze at −20 °C for storage beyond 6 months.
After reconstitution: refrigerate at 2–8 °C; typically stable 4–8 weeks with bacteriostatic water. Do not freeze once mixed.
Pre-mixed pens: arrive ready to use — refrigerate at 2–8 °C with the cap on and never freeze.
General: avoid direct sunlight, heat and repeated temperature swings; minimise agitation.

Semax

Semax is a synthetic peptide analogue derived from a fragment of adrenocorticotropic hormone (ACTH). It is used as a reference compound in neuropeptide research.

About the compound

Semax is studied in laboratory research for its interactions within neuropeptide signalling pathways, including research examining brain-derived neurotrophic factor (BDNF) in laboratory models. It remains an active subject of neuropeptide research.

Semax Cognitive Research Human Subjects

Semax Improves Attention and Processing Speed in Human Subjects Without Psychostimulant Side Effects

Neuroscience Research Communications · Kaplan et al., 1996

A human clinical study evaluated Semax across measures of selective attention, working memory, and information processing speed. Semax-treated participants demonstrated statistically significant improvements in attention task accuracy and processing speed vs control, without sedation, anxiolytic blunting, or psychostimulant tolerance. These human findings form part of the evidence base supporting Semax's registration as a licensed pharmaceutical in Russia and Ukraine for stroke, cognitive impairment, and traumatic brain injury.

Semax: ACTH(4-10) Analogue Activity and BDNF/TrkB Modulation in Hippocampal Research

Brain Research · Dolotov et al., 2006

Semax is a synthetic heptapeptide analogue of ACTH(4-7) with enhanced metabolic stability. Research demonstrated that Semax significantly upregulated both BDNF and TrkB receptor expression in the rat hippocampus, identifying a potential neuroprotective mechanism. Additional studies characterised improvements in learning, memory consolidation, and attention in controlled animal models. Semax holds regulatory status as a neuroprotective drug in Russia and Ukraine.

Semax Increases Brain-Derived Neurotrophic Factor Protein in Rat Basal Forebrain

Journal of Neurochemistry · Dolotov et al., 2006

A rat study showing that Semax, a synthetic ACTH(4–10) analogue, binds to specific high-affinity sites in the basal forebrain and, following intranasal dosing (50–250 µg/kg), rapidly increases BDNF protein within three hours. This provides protein-level confirmation of Semax engaging the BDNF–TrkB neurotrophic signalling axis that underlies its documented cognitive effects.
