The scientific reference for nootropic research peptides
Evidence-based, neutrally written profiles of the peptides most relevant to cognitive enhancement, neuroprotection, focus, mood, and brain health research — with mechanism-of-action breakdowns, study summaries, safety profiles, and UK regulatory context.
Some compounds discussed are authorised UK prescription-only medicines; the rest have no UK marketing authorisation found on this site's checks. Content is educational and not medical advice.
Why this site
Educational reference, not a marketplace
Mechanism-first
Every entry leads with the molecular mechanism before the marketing.
Studies summarised
Plain-English summaries of the peer-reviewed evidence — what it shows and what it doesn't.
Regulatory clarity
Explicit UK and EU regulatory status on every page. No grey-area implications.
Evidence, not hype
Neutral scientific tone. We do not market peptides for human use.
Peptide library
Featured research peptides
Six of the most-studied peptides in the cognitive enhancement and neuroprotection literature.
Semax
A synthetic heptapeptide analogue of ACTH(4-10) developed in Russia for cognitive enhancement, neuroprotection, and stroke recovery research.
Read profileSelank
A synthetic heptapeptide analogue of tuftsin developed for anxiolytic and immunomodulatory research, with measurable effects on attention and mood.
Read profileDihexa
An orally active hexapeptide derivative of angiotensin IV, characterised in academic research as among the most potent known pro-cognitive compounds in animal models.
Read profileCerebrolysin
A complex mixture of low-molecular-weight peptides and free amino acids derived from porcine brain tissue, studied extensively in cognitive decline and post-stroke recovery research.
Read profileDSIP
A nonapeptide originally isolated from the cerebral venous blood of sleeping rabbits, studied for sleep modulation, stress resilience, and indirect cognitive effects.
Read profileNoopept (Peptide Note)
A small proline-containing dipeptide derivative — technically a peptidomimetic — developed in Russia as an orally active cognitive enhancer with structural lineage to piracetam.
