Selank and Semax are synthetic heptapeptides studied in preclinical research on memory, attention, BDNF modulation, and anxiolytic pathways. Both have short half-lives, are typically administered intranasally in research settings, and target different neuronal mechanisms: Selank is derived from Tuftsin, while Semax is a fragment of ACTH(4-10).
Selank and Semax are often examined in parallel so labs can compare Tuftsin-derived anxiolytic pathways against ACTH-derived nootropic mechanisms side by side.
Selank is a synthetic heptapeptide whose sequence is based on Tuftsin, an endogenous immunomodulatory tetrapeptide. The modification gives Selank greater plasma stability than the native Tuftsin molecule. In preclinical research it is examined in connection with anxiolytic pathways, GABAergic interactions, stress resilience, and cognitive endpoints. Research protocols typically use intranasal administration. Selank is supplied strictly for research purposes and is not approved for human or veterinary use.
Nootropic and neuroprotective research peptides, primarily Selank and Semax. Selank is a synthetic heptapeptide structurally derived from Tuftsin, studied in preclinical work on anxiolytic effects, stress resilience, and GABAergic pathways. Semax is a synthetic heptapeptide derived from the ACTH(4-10) fragment and is examined in research on memory, attention, BDNF modulation, and neuroprotection. Both peptides have short systemic half-lives and are typically administered intranasally in research settings, a route chosen because it allows more direct access to central compartments. The category groups nootropic and cognitive research approaches so investigators can compare two mechanistically distinct candidates within a single workflow.
Each peptide is tested by reverse-phase HPLC for a purity of at least 99 percent. Peptide identity is confirmed by mass spectrometry to verify sequence and molecular weight. Certificates of analysis with the relevant specifications are available on request, so research teams can integrate the documentation into internal QC workflows and study records. All peptides in this category are supplied strictly as Research Use Only and are not intended for human or veterinary use. For methodological questions about handling, analytical reports, or the reference literature underlying Selank and Semax, our team is available to share the relevant sources.
Stored at minus 20 degrees Celsius and protected from light, the lyophilised powder remains stable for up to 24 months. For reconstitution we recommend bacteriostatic water added slowly down the inner wall of the vial rather than directly onto the pellet, which helps preserve peptide integrity. Once reconstituted, the vial should be kept between 2 and 8 degrees Celsius and used within 28 days. For intranasal research protocols involving Selank or Semax, labs commonly use separate dosing implements per peptide to avoid any cross-contamination between the two compounds. A complete reconstitution protocol is included in the companion peptide guide.
