DSIP (Delta Sleep-Inducing Peptide) addresses the critical relationship between stress and sleep quality, normalising the HPA axis and promoting restorative rest
It was originally isolated in 1977 from the cerebral venous blood of rabbits and has since been found to be present in small amounts in human brains and plasma, with higher concentrations later in the day.3 4 It, or a similar substance, is also present at higher concentrations in human breast milk.5 Because DSIP can cross the blood-brain barrier and is easily absorbed via the gut (unusual for a peptide), some researchers have hypothesized that it may facilitate post-feeding sleep tendencies among newborns, though it remains unclear whether DSIP truly has a hand in neonate sleep-wake cycles.4 5 6 Its mechanism of action is likewise unclear, but it may have something to do with endocrine regulation
Other Integrative Peptides products worth knowing The BPC-157 products represent the company flagship offerings, but the full product line includes several other formulations relevant to peptide researchers
Absence of Common Growth Hormone Side Effects: Because AOD-9604 does not bind to growth hormone receptors or elevate IGF-1, it avoids edema and fluid retention, joint pain and stiffness, carpal tunnel syndrome, glucose elevation and insulin resistance, increased cancer risk concerns from IGF-1 elevation, organ growth or acromegaly features with long-term use, and thyroid function suppression
