This page compares the laboratory 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 and dispatched tracked from inside Europe. Follow any name through to its product page for the full research profile, specifications and references.
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.
| Compound | Studied in laboratory models of… | Vial |
|---|---|---|
| Selank | Anxiolytic and nootropic research (tuftsin analogue) | 11 mg vial |
| Semax | Nootropic and neuroprotective research (ACTH 4–10 fragment) | 11 mg vial |
| Combined nootropic research (Selank with Semax) | 10 mg vial | |
| DSIP | Sleep-regulation, stress-response and neuroendocrine pathways (delta sleep-inducing peptide) | 5 mg vial |
PowerfullyPeptides lists Selank (11 mg), Semax (11 mg) and DSIP (5 mg). Each is a research compound studied in laboratory models relevant to neuropeptide and cognitive research and is supplied as a lyophilised vial for laboratory research use only.
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.
A purity specification is a target. Independent reports are published only for the samples shown in our COA library; not every product has a report.
Selank, Semax and DSIP are currently in stock.
PowerfullyPeptides ships to research buyers across Europe, dispatched from inside the EU. Orders are dispatched the same working day on orders before 2:00 PM, tracked from inside Europe. Prices are in euro and every order is invoiced for laboratory research use only.
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.
Selank is a synthetic heptapeptide derived from tuftsin; Semax is related to the ACTH sequence. Their Selank and Semax specifications remain separate. Research descriptions do not establish human or veterinary benefits.
Published laboratory reports describe the tested samples only. Reports are not available for every product. Check the individual listing for current availability and documentation.
