Cognitive & neuro research peptides
The cognitive category collects short neuromodulatory sequences studied in memory, anxiety-behaviour and neurotrophic models. Several are derived from endogenous regulatory peptides and are used in the literature as tools for probing BDNF expression and monoamine turnover.
About this category
Route of administration in published work is unusually varied for this class — intranasal models are common alongside parenteral ones — which affects how researchers interpret exposure data. Each product page notes what the reference literature actually used.
As with the rest of the catalogue, nothing here is characterised for human use. These are in-vitro and preclinical reference compounds supplied with lot-level analytical documentation.
- Short neuromodulatory sequences with published model context
- Half-life and administration notes drawn from reference literature
- ≥99% HPLC main-peak purity targets, verified per batch
- Tracked EU shipping, research-use declaration included

Frequently asked questions
What makes a peptide 'nootropic' in the literature?
It is a shorthand for compounds studied against learning, memory or anxiety-behaviour endpoints — not a regulatory or pharmacological classification.
Are the cognitive peptides stable at room temperature?
Lyophilised powder tolerates short transit at ambient temperature; long-term storage is refrigerated or frozen. Details are on each product page.
Do you supply diluent with these kits?
Bacteriostatic water and acetic acid are sold separately under lab supplies, as liquid multi-vial kits.
Other categories
All compounds are supplied for in-vitro laboratory research use only. Nothing on this page is medical advice or a recommendation for human or veterinary use.
Cognitive & neuro research peptides: selection guide
Compounds in this group
Cognitive and neuro research peptides are studied in models of neurotrophic signalling, stress response and sleep architecture. Semax and Selank are short synthetic peptides first developed in Russian research institutes, based on ACTH and tuftsin fragments respectively. Their combination vial pairs both. Dihexa is a small angiotensin-IV-derived compound studied for hepatocyte-growth-factor signalling.
Less common listings
Cerebrolysin is a porcine-brain-derived peptide mixture rather than a single defined sequence, so batch documentation describes composition differently from synthetic peptides. Pinealon is a tripeptide from the Khavinson short-peptide series. PE-22-28 is a Spadin-derived peptide studied at the TREK-1 channel. DSIP (delta sleep-inducing peptide) is a nonapeptide studied in sleep research since the 1970s.
Choosing between them
Researchers usually select by mechanism: BDNF and neurotrophin pathways for Semax and Dihexa, GABAergic and anxiolytic-model readouts for Selank, and sleep-stage models for DSIP. Defined synthetic sequences such as Semax, Selank and DSIP are easier to verify by HPLC and mass spectrometry than mixtures like Cerebrolysin.
Documentation and storage notes
Semax and Selank are usually supplied as acetate salts, and some published methods use modified forms with an added amino acid tail for stability. Check the sequence shown on the product page against the one in the paper you are following. DSIP and Pinealon are short and stable as lyophilised powders. Dihexa is a small modified compound, and its certificate should report a molecular weight consistent with its specific structure.
Store vials refrigerated and protected from light. Cerebrolysin is normally supplied as a solution rather than powder, so it needs different handling from the lyophilised peptides in this category. Read its product page before ordering alongside other items. As with every category, we do not publish dosing instructions or describe effects in people. These are laboratory reference materials, and the categories describe research areas only.
