DSIP Nasal Spray

Delta Sleep-Inducing Peptide, DSIP nasal spray is a naturally occurring neuropeptide which promotes the spindle plus delta EEG activity and inhibits motor activities.

Considered as an amphiphilic protein, DSIP is a peptide with hydrophilic and lipophilic properties. It can be found in the limbic system, hypothalamus, limbic system, tissue fluid, and pancreas.

Studies suggest DSIP works in the brain mediated by N-methyl-D-aspartate receptors (NMDA). These are responsible for sleep function, learning and memory function.

As the glutamate and glycine bind together, this receptor is activated. When it functions at its best, it lets any charged ions begin flowing thru the cell membrane. NMDA receptor plays a crucial role in controlling memory function and synaptic plasticity.

NMDA receptor has low molecular stability. That’s why experts believe DSIP makes compounds rich in carrier proteins. Studies show that these proteins stop degradation. It is regulated by glucocorticoids, which is a class of corticosteroids (a type of steroid hormone).

Simply, glucocorticoids bind to the glucocorticoid receptor. They serve as the body’s immune system mechanism that reduces inflammation during allergies of autoimmune diseases.

DSIP Nasal Spray Benefits


Promoting and regulating sleep is one of the essential DSIP nasal spray benefits. It’s not a sedative, according to scientists, but rather a sleep-inducing substance. So aside from sending you to sleep, it also promotes sleep regulation.

There are two main types of sleep: deep and light. REM and NREM sleep are two distinct types of sleep. Random Eye Movement and Non-Random Eye Movement sleep are two different things. DSIP nasal spray supplement does not alter the length of these sleep cycles, unlike many other sleep aids. When it comes to falling asleep, however, it does the opposite.

In addition, DSIP nasal spray could present a potential treatment for insomnia. Despite this, scientists still need to conduct extensive research into its effects on this sleep disorder and also potential side effects.

Clinical research studies have shown DSIP to induce feelings of sleepiness and increase sleep time by nearly 60 per cent in human subjects using a control group in clinical research. These findings are significant.


Several studies have shown that adrenocorticotropic hormone secretion (ACTH) is linked to a high dosage of DSIP. However, the morning peak of ACTH and the night time low of ACTH are considered normal in a person with a healthy circadian cycle. In the meantime, other clinical studies show that the effects of DSIP peptides also include reducing ACTH levels, enhancing sleep.

Chronic pain

A short-term benefit from current medications such as NSAIDs and opiates may outweigh the risks of long-term use, which can lead to life-threatening side effects. That’s why scientists are so eager to find an alternative analgesic to treat chronic pain syndromes without causing life-threatening side effects.

DSIP nasal spray was found to reduce pain perception significantly and develop a general sense of well-being in a small DSIP human study. In addition, it was found that DSIP treatment may be beneficial for patients dependent on pain medications because it reduces detox symptoms.

Natural analgesic effects are produced by DSIP in rats, according to studies conducted on the animals. In addition, DSIP sleep peptide has been shown to reduce pain significantly, but scientists aren’t sure if this is because of direct or indirect effects.

Blood Pressure

An antihypertensive effect has been demonstrated in clinical studies using the DSIP injection method. In addition, antihypertensive in animal studies have shown that DSIP dosage can keep blood pressure levels stable.

Muscle gains

Researchers believe that delta sleep inducing peptides also improve and stimulate bone and muscle growth. The peptide DSIP hindered Somatostatin, a protein generated by muscle cells that inhibits muscle growth. Conversely, DSIP peptide aids muscle growth by inhibiting the hormone somatostatin.

Prevention against cancer

While most cancer studies centre on finding a cure, a small group of researchers are interested in seeing how to inhibit cancer from developing. The principal goal is to activate the body’s immune system to eliminate cancerous cells before spreading.

Preclinical studies found that the use of delta sleep inducing peptides exhibits strong cancer prevention results using rodent subjects – more potent than other vaccines examined to date. Every month, starting at three months old and continuing until they died, female models were given DSIP for five days in a row. As a result of receiving the treatment, there was a decrease in bone marrow defects and tumour development.

There is also the option to buy DSIP peptide vial and buy DSIP pre mixed peptide.
