DSIP 2mg | Delta Sleep-Inducing Peptide | Neuroendocrine & Sleep Research Peptide 

DSIP (Delta Sleep-Inducing Peptide) is a natural neuropeptide first discovered in the hypothalamus, known for its involvement in sleep regulation, stress modulation, and endocrine balance.

At West Lab Chemicals, we supply DSIP 2mg (Research Grade) with ≥99% purity (HPLC verified), produced in GMP-certified facilities for consistent, reliable, and high-quality research outcomes.

DSIP has been studied for its potential effects on sleep cycles, hormonal homeostasis, cortisol modulation, and neuroprotective activity, making it a core research compound in neuroscience, sleep, and stress physiology.

What is DSIP?

Delta Sleep-Inducing Peptide (DSIP) is a nonapeptide (9 amino acids) with the sequence:
Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu.

It is an endogenous peptide that crosses the blood-brain barrier and interacts with neuroendocrine and GABAergic systems.

In research models, DSIP has demonstrated:

• Regulation of slow-wave (delta) sleep

• Modulation of stress hormones (ACTH, cortisol)

• Support of growth hormone (GH) and LH release

• Neuroprotective and anti-oxidative properties under stress
