DSIP 10mg

DSIP (Delta Sleep-Inducing Peptide) | 15mg

Sleep is not a passive state — it is the foundation of recovery, hormonal balance, and cognitive resilience. DSIP is a naturally occurring neuropeptide first isolated in 1977 from the cerebral blood of rabbits during deep slow-wave sleep. Found in the hypothalamus, limbic system, and pituitary gland, it is one of only two sleep peptides to have been purified, characterised, and studied extensively in both animal and human research settings.

Unlike conventional sleep aids that force sedation by suppressing the central nervous system, DSIP works by supporting and optimising the body’s natural sleep architecture — making it one of the most unique and intriguing compounds in neuropeptide research today.

What Research Suggests DSIP May Support:

Sleep Quality & Architecture — Research points to DSIP’s ability to promote slow-wave delta sleep — the deepest and most restorative phase of the sleep cycle — while supporting shorter sleep onset and improved overall sleep efficiency without producing the sedative blunting associated with conventional sleep compounds.

Stress Modulation & Cortisol Regulation — Studies suggest DSIP can act as a stress-limiting factor by decreasing basal corticotropin levels and blocking its release, helping to buffer the hormonal impact of chronic stress on the body’s sleep-wake cycle and overall nervous system balance.

Growth Hormone Support — Research indicates DSIP stimulates the release of somatoliberin and somatotrophin secretion while inhibiting somatostatin, supporting natural GH release during sleep — a key driver of overnight recovery, tissue repair, and metabolic regulation.

Neuroprotection — Studies have identified DSIP’s potential to protect neurons from oxidative stress, with research suggesting possible applications in the study of neurodegenerative conditions including Alzheimer’s and Parkinson’s disease.

Neurological Recovery — Animal research has demonstrated that intranasal DSIP administration led to meaningful improvements in motor coordination and function following stroke, pointing to broader neuroprotective and neuroregenerative applications.

Pain Modulation — Preclinical research has demonstrated a potent antinociceptive effect, with studies suggesting DSIP may influence pain perception pathways — an area of growing interest given its multi-receptor activity in the central nervous system.

Longevity & Geroprotective Effects — Animal studies have shown that long-term DSIP administration reduced spontaneous tumour incidence, decreased chromosomal aberrations in bone marrow cells, and extended maximum lifespan — positioning it as a compound of compelling interest in longevity and healthy ageing research.
