Cognitive & nootropic peptides
Cognitive and nootropic research peptides cover neurotrophic and neuromodulatory compounds studied for signaling, plasticity, and sleep-regulation models, including Semax, Selank, Cerebrolysin, DSIP, Dihexa, Bronchogen, and VIP.
Each peptide is verified to at least 99% purity by analytical HPLC and mass spectrometry with a batch certificate of analysis included. Made in the USA and supplied strictly for laboratory research use.
≥99%Bronchogen
Bronchogen is a synthetic tetrapeptide (Ala-Glu-Asp-Leu, AEDL) belonging to the family of short peptide bioregulators first characterized by Khavinson and colleagues.
Certificate of AnalysisLOT #BRO151390-75Q · 99.50%PASS
≥99%Cerebrolysin
Cerebrolysin is a peptide preparation produced by the standardized enzymatic hydrolysis of purified porcine brain proteins, yielding a defined mixture of low-molecular-weight neuropeptides and free amino acids.
Certificate of AnalysisLOT #CER154256-85U · 99.96%PASS
≥99%Dihexa
Dihexa (PNB-0408) is a small-molecule oligopeptide derived from angiotensin IV, engineered to potentiate hepatocyte growth factor (HGF) signaling at its receptor c-Met.
Certificate of AnalysisLOT #DIH152594-78K · 99.54%PASS
≥99%DSIP
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide first isolated from the cerebral venous blood of rabbits during electrically induced slow-wave sleep.
Certificate of AnalysisLOT #DSI152801-57T · 99.81%PASS

Which nootropic research peptides are available?
The collection includes Semax, Selank, Cerebrolysin, DSIP, Dihexa, Bronchogen, VIP, and the Selank/Semax blend, studied in neurotrophic, neuromodulatory, and sleep-regulation research models. Research use only.
What is the difference between Semax and Selank?
Semax and Selank are both short peptides studied in neuromodulation research, but they derive from different parent sequences and are investigated for different signaling profiles. Some researchers study them together via the Selank/Semax blend. For research use only.
What purity are these nootropic peptides, and do they include a COA?
Every compound is verified to at least 99% purity by third-party analytical HPLC and mass spectrometry, and each vial ships with a batch-specific certificate of analysis (COA) documenting identity and purity for that lot.
Do you ship cognitive and nootropic peptides, and how fast?
We ship within the United States only, via UPS, with typical delivery of 1 to 5 business days after dispatch. Orders are usually dispatched within one business day. All products are supplied for laboratory research use only.
