What exactly is Selank, and why do research programs pick the 10mg tier?
Selank is a synthetic heptapeptide analog of the immunomodulatory tetrapeptide tuftsin, extended with a Pro-Gly-Pro C-terminal fragment (full sequence: Thr-Lys-Pro-Arg-Pro-Gly-Pro) to improve enzymatic stability. It is studied in pre-clinical anxiolytic models for GABAergic-modulation activity. The 10mg per vial tier supports full-course behavioural-model protocols after 1 to 2 mL reconstitution without leaving reconstituted material sitting past the 30-day mark.
What does this specific lot’s CoA cover?
Every Selank lot is independently assayed by reverse-phase HPLC for purity and by mass-spectrometry for identity against the theoretical mass of the seven-residue sequence, including verification of the Pro-Gly-Pro tail that distinguishes Selank from native tuftsin. Lot-specific certificates of analysis are being catalogued and will be publicly listed on the product page as they come online.
How do I reconstitute a 10mg Selank vial?
- Alcohol-swab the vial stopper and let it dry.
- Draw 1 to 2 mL of bacteriostatic water into a sterile syringe.
- Inject the diluent slowly against the vial wall, avoiding direct impact on the lyophilized cake.
- Roll the vial between the palms to dissolve. Do not shake.
- Refrigerate the reconstituted vial at 2 to 8 °C and use within 30 days.
Selank vs Semax: how do research programs pick between them?
Both Selank and Semax are Russian-origin heptapeptides used across nootropic-model literature, but their pharmacological framing is different. Selank is a tuftsin-family analog studied for GABAergic-modulation and anxiolytic endpoints; Semax is an ACTH(4-10) fragment studied for BDNF-expression and neurotrophic endpoints. Programs interested in anxiety-related behavioural readouts favour Selank; programs interested in learning, memory, and neurotrophic markers favour Semax. Blended-format vials such as Adamax combine both alongside a BPC-157 component.
Can Selank and Semax be run together?
They frequently are in the pre-clinical literature — because their reported mechanisms are non-overlapping (GABAergic vs BDNF-related), simultaneous exposure lets a single arm probe two mechanistic axes at once. The Prescott catalogue supports this pairing by stocking both single-molecule vials as well as the Adamax blend.
