Neuropeptide & Cognitive Research
This page compares the research peptides PowerfullyPeptides stocks that are studied in laboratory neuropeptide and cognitive research — anxiolytic, nootropic, neuroprotective and sleep-regulation models. It is a reference for research buyers in Europe, not a ranking and not a claim that any peptide is effective for any outcome.
Every compound below is supplied strictly for laboratory research use only — not for human or veterinary use. Each is specified to a ≥99% purity target, lot-tracked, and dispatched tracked from inside the EU (Ireland). Follow any name through to its product page for the full research profile, specifications and references.
For research use only. Every compound listed is supplied for laboratory research — not for human or veterinary use — and nothing on this page describes or implies any therapeutic outcome, benefit or ranking.
Neuropeptide and cognitive research covers peptides studied for pathways such as anxiolytic and nootropic signalling, neuroprotection, neurotrophic factor expression and sleep and stress regulation. The compounds here are grouped by that shared research context and span single peptides and a research blend.

No. Every compound on this page is supplied strictly for laboratory and in-vitro research — not for human or veterinary use. We make no medical, therapeutic or performance claims, and nothing here should be read as guidance for use in humans or animals.
Material is specified to a ≥99% purity target and is lot-tracked, so a batch can be traced through your records. Independent per-batch Certificate-of-Analysis testing is our published testing standard — see our COA page for how identity and purity are documented.
Selank, Semax and Selank + Semax Blend are currently in stock. DSIP is listed as sold out while a new supplier batch is sourced and independently tested — join the Insiders list on any product page for the restock notice.
