DSIP 15mg (Delta Sleep-Inducing Peptide)

DSIP 15mg is a high-purity synthetic research peptide supplied as a lyophilized powder for laboratory and scientific investigation.

DSIP, also known as Delta Sleep-Inducing Peptide, is a naturally occurring nonapeptide (9 amino acids) first isolated from brain tissue in the 1970s. It is primarily studied for its potential role in modulating sleep architecture — specifically promoting deeper, more restorative delta-wave (slow-wave) sleep — as well as influencing stress response, neuroendocrine regulation, and recovery processes.

Research Areas of Interest:

• Sleep quality and circadian rhythm regulation
• Stress and anxiety-related pathways
• Physical and neurological recovery
• Potential neuroprotective and analgesic effects
