Nootropic & neuropeptides
Cognitive peptides are short neuropeptide sequences studied in research contexts around neurotrophic signalling, attention, and stress response. Most of the compounds in this category came out of Russian neuropeptide research programs — Semax and Selank are both fragments engineered from endogenous sequences for greater metabolic stability. Canada Peptides carries this category priced and shipped in CAD, for laboratory and research use only.
In research literature the label covers peptides studied for effects on neurotrophic factors — BDNF and NGF in particular — rather than a shared receptor target. Semax is an ACTH(4-10) fragment studied around BDNF expression and neuroprotection. Selank is a tuftsin analogue investigated on the anxiolytic side, around GABAergic and monoamine signalling. Because the two are studied for adjacent but distinct pathways, they are frequently researched together — see Semax vs Selank for how they differ.
Cerebrolysin sits apart from the single-sequence peptides here: it is a neurotrophic peptide fraction rather than one defined molecule, which changes how it is characterized and handled in research settings. It is stocked in this category because the research context — neurotrophic signalling — is the same.
This category is available as standard lyophilized vials and, for Semax and Selank, as reloadable 3 mL peptide pens. Intranasal and subcutaneous routes both appear in the literature for this class, which affects reconstitution volume — the dosing-math guide and reconstitution 101 cover the arithmetic, and the dosage calculator does it for you.
Cerebrolysin — a research overview
A research overview of the cerebrolysin peptide preparation: what the porcine brain hydrolysate actually is, what its mechanism claims do and don't support, and how its contested stroke, vascular dementia and TBI trial data reads.
Semax vs Selank — compared
Semax vs Selank compared across sequence, mechanism, half-life, registered indications and depth of evidence — and where the shared Pro-Gly-Pro design stops being a shared mechanism.
Semax dosage — research dosing notes
What the literature actually reports on Semax dosage: the 0.1% and 1% intranasal concentrations, the 6,000 µg/day post-stroke regimen, half-life context, and reconstitution math for a 5 mg vial.
Semax — a research overview
Semax is a synthetic ACTH(4-10) analogue studied as a nootropic and neuroprotective peptide. Its mechanism, the BDNF/NGF neurotrophic story, and what the (Russia-dominated) research actually shows.
Selank — a research overview
Synthetic anxiolytic heptapeptide with GABAergic and immunomodulatory roots, clinically approved in Russia for stress and anxiety.
