Nootropic & neuropeptides
Cognitive Peptides in Canada
7 compounds in stock
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.

What makes a peptide 'nootropic'
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 and peptide fractions
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.
Formats and handling
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.

Cognitive peptides FAQ
- What are nootropic peptides?
- Nootropic peptides are short amino-acid sequences studied in research contexts around cognition-related signalling — most often neurotrophic factors such as BDNF, plus monoamine and GABAergic pathways. Semax and Selank are the two most-studied examples. The term describes a research area, not an approved drug class.
- Can I buy nootropic peptides in Canada?
- Yes. Canada Peptides stocks research-grade Semax, Selank, the Semax + Selank blend and Cerebrolysin, priced in CAD and shipped within Canada. They are supplied strictly for laboratory and research use.
- What is the difference between Semax and Selank?
- Semax is an ACTH(4-10) fragment studied around BDNF expression, neuroprotection and attention. Selank is a tuftsin analogue studied on the anxiolytic side, around GABAergic and monoamine signalling. They target different pathways, which is why a combined Semax + Selank blend exists.
- Are cognitive peptides sold as blends?
- Yes. A Semax + Selank blend is stocked at 10 mg and 20 mg alongside the standalone 5 mg vials, for research protocols that examine both sequences together.
- Are these peptides research use only?
- Yes. Everything in this category is supplied strictly for laboratory and research use. Nothing on this page is medical advice or a therapeutic claim.
