Research category
UK supplier of seven neuropeptide research compounds spanning CNS, circadian, neurohormone and HPG-axis pathways. From the Russian-origin BDNF-modulating Semax and Selank to the cyclic neurohormone Oxytocin and the HPG-axis modulator Kisspeptin-10. Every batch independently HPLC-verified by Janoshik Analytical at 99%+ purity. Research use only - not for human consumption.
The neuropeptide research family is broader than the other categories on this site - it spans multiple receptor systems and neurochemical pathways unified by their CNS site of action or neurohormone biology. Compounds here are studied in published literature for cognition, anxiolysis, sleep architecture, social-bonding research, circadian biology, the hypothalamic-pituitary-gonadal (HPG) axis, and melanocortin signalling.
This is the most chemically diverse category in our catalogue. Compounds range from a 4-residue tetrapeptide to small-molecule indoleamines (melatonin) to cyclic 7-residue melanocortin analogues.
| Compound | Class | Primary research focus |
|---|---|---|
| Semax | 7-AA ACTH(4-10) analogue | BDNF / cognition / nootropic research |
| Selank | 7-AA tuftsin analogue | Anxiolytic / GABAergic research |
| DSIP | 9-AA Delta Sleep-Inducing Peptide | Sleep / circadian research |
| Melatonin | Indoleamine neurohormone | Circadian / antioxidant research |
| Oxytocin | 9-AA cyclic neurohormone | Social bonding / HPA-axis research |
| Kisspeptin-10 | 10-AA C-terminal kisspeptin fragment | HPG axis / GnRH research |
| PT-141 | 7-AA cyclic melanocortin agonist | MC4R / sexual behaviour research |
Semax and Selank are two of the most-cited neuropeptide research compounds developed in Russian research literature. Both are 7-residue peptides approved as therapeutics in Russia/CIS countries and characterised extensively in published research elsewhere.
Direct comparison: Semax vs Selank.
Two compounds focus on circadian and sleep-architecture pathways:
PT-141 (Bremelanotide) is a 7-residue cyclic α-MSH analogue with selective MC4R activity at relevant doses. The melanocortin pathway overlaps with neuropeptide research because MC4R signalling extends into central appetite and sexual-behaviour pathways. Approved (Vyleesi) in some jurisdictions for research-relevant indications.
Note: a separate Melanocortin Research tier in our catalogue includes MT-1 (Afamelanotide) and MT-2 (Melanotan II). PT-141 sits at the boundary because of its CNS-pathway research focus.
Semax is the canonical reference for BDNF / nootropic research literature.
Selank is the canonical reference for GABAergic / anxiolytic neuropeptide research.
DSIP for delta-wave / slow-wave research; Melatonin for circadian-rhythm and antioxidant research.
Kisspeptin-10 for GnRH-pulse research; Oxytocin for HPA-axis and social-bonding research.
All compounds in this category are supplied as lyophilised powder in sealed glass vials. Reconstitute with bacteriostatic water added slowly down the side wall, swirling gently. Melatonin is light-sensitive - store in amber containers. Use the on-site Reconstitution Volume Calculator for mg/mL maths.
Compounds in this category are independently HPLC-verified by Janoshik Analytical at 99%+ purity. Where a Janoshik report has been issued for the current batch it is supplied with the order, and verification records are published on the Purity page.
