in the evening, before bed nasal application 1-2 sprays per nostril Scientific sources Delta-sleep-inducing peptide: a review scientific review A review article summarizing studies on DSIP, describing its impact on promoting delta sleep (deep sleep) in various species (rabbits, mice, rats, humans)
[12] It even helped to increase mobility in chronically stressed rats in that study
Theres a newer peptide called PDA, or pentadeca arginate, that has a very similar molecular structure as BPC-157, but instead of it being an acetate, its an arginate essentially just swapping out one amino acid for another
Studies also examine synaptic-plasticity mechanisms and angiotensin-derived peptide signaling across in-vitro and ex-vivo research systems
Remember, these are just general guidelines
