DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide synthesised in the hypothalamus. It promotes deep, restorative delta-wave sleep and modulates the HPA axis, affecting cortisol and growth hormone secretion. Plasma concentrations follow a circadian rhythm, declining with age.
Every batch is independently tested by a 3rd party laboratory. Certificate of Analysis available below.

Research Overview
About this compound
What does the research say?
DSIP (Delta Sleep-Inducing Peptide) was first isolated from rabbit brain in 1977. It is a nine-amino acid peptide naturally synthesised in the hypothalamus that promotes a specific type of deep sleep characterised by increased delta-wave EEG activity. This delta sleep phase is associated with physical recovery, growth hormone release, and memory consolidation.
DSIP interacts with the hypothalamic-pituitary-adrenal (HPA) axis, modulating cortisol and ACTH secretion. Brain and plasma DSIP concentrations follow a marked circadian rhythm, with low levels in the morning and higher levels in the afternoon. Published research has also demonstrated anti-tumour properties: lifetime DSIP administration decreased spontaneous tumour incidence 2.6-fold in mice.

Why does quality matter with DSIP?
DSIP is a small nonapeptide with specific sequence requirements for biological activity. Impure or degraded material will not produce the characteristic delta-wave sleep response observed in published studies.
At Camo Chem, every batch is tested by an independent 3rd party laboratory. We publish the full Certificate of Analysis for every batch, and you can verify the results directly with the lab. We do not self-certify. Ever.
