Cognitive Peptides

Buy cognitive peptides and nootropic peptides online in the UK — pharmaceutical-grade semax, selank, cerebrolysin and DSIP for focus, memory, anxiety and neuroprotection. All compounds synthesised to ≥98% purity with Certificate of Analysis on every batch.

Originally developed in Soviet and Russian research programmes, these peptides are now used globally for cognitive enhancement, stress resilience and neurological support — without the dependency risk of conventional stimulants or anxiolytics.

Our most popular cognitive peptides:

Semax — ACTH-derived nootropic that increases BDNF, enhances dopamine and serotonin activity, and supports memory consolidation and focus. Used widely for brain fog, mental fatigue and cognitive performance. From £119/30-day supply.

Selank — anxiolytic nootropic that modulates GABA and BDNF for calm focus, anxiety reduction and stress resilience — without sedation or dependency. From £109/30-day supply.
