Buy DSIP (Delta Sleep-Inducing Peptide) 5mg — a nonapeptide studied for sleep regulation, HPA axis modulation, stress response, and neuroprotection. 99%+ purity, fast US shipping. Research use only.
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide first isolated from the cerebral venous blood of rabbits in sleep states. It has since been studied across a broad range of neuroendocrine and stress-related applications beyond its original sleep-induction discovery.
DSIP research has investigated its effects on sleep architecture modulation, particularly the enhancement of delta (slow-wave) sleep. Beyond sleep, researchers have studied DSIP for its effects on stress hormone regulation — specifically its ability to modulate ACTH and cortisol secretion — making it of interest in HPA axis research. Additional studies have examined its antioxidant properties, neuroprotective effects in models of neurodegeneration, and role in pain modulation. Search volume for “dsip peptide” has grown from 1,600/month in 2024 to over 9,000/month in 2026, reflecting significantly expanding research interest.
For research and laboratory use only. Not intended for human consumption.
