DSIP Nasal Spray Latvia

DSIP peptide, also known as Delta Sleep-Inducing Peptide, is a naturally occurring compound in the body. It is primarily known for its potential to promote deep and restful sleep. DSIP has been studied for its potential applications in treating various sleep disorders, promoting overall sleep quality and has shown potential in treating certain pain conditions.

DSIP Nasal Spray

DSIP nasal spray Latvia is a neuropeptide that affects several endocrine and physiological processes in the central nervous system. It is currently being studied for its effects to reduce oxidative stress and normalize myocardial contractility, in addition to a potential treatment for major depression.

Delta Sleep Inducing Peptide is a well-known nonapeptide traditionally used to treat insomnia and stress. For over 40 years, Latvia scientists have studied the effects of Delta Sleep Inducing Peptide on mice, with promising results.

Delta sleep peptide has been found to protect against stress-induced metabolic disorders in mice and other animals. In addition, animal studies have shown it can improve physical performance and hormone levels. DSIP nasal spray is a synthetic version of the sleep-inducing hormone produced naturally in the pituitary, hypothalamus, and adrenal glands.

DSIP Research


In one clinical trial, the effects of Delta sleep-inducing peptide on sleep were studied in 16 chronic insomniacs using a parallel-groups design with matched pairs. The Latvia research looked at sleep structure, sleep quality, and subjective tiredness [1]. Results showed that Delta Sleep Inducing Peptide had better sleep efficiency and shorter sleep latency than placebo in objective sleep quality tests. In addition, the DSIP group improved on one measure of subjective tiredness.

At night, the human body produces essential hormones and essential physiological processes. Many sleep aids and medications alter the period or length of time of these sleep cycles, which can be problematic for the user. The disruption of these natural sleep cycles reduces the efficiency and quality of sleep. Delta Sleep Inducing Peptide has been proven not to disrupt sleep cycles in Latvia scientific trials [2].

Pain relief

In the short term, medications like Non-steroidal anti-inflammatory drugs (NSAIDs) and opiates work but can have long-term devastating side effects, so researchers are eager to find a new analgesic that doesn’t have such severe side effects [3].

A small Latvia  study using rodents found the peptide can substantially decrease pain perception and improve overall well being. It also helped eliminate withdrawal symptoms in subjects who were dependent on painkillers.

The natural analgesic properties of Delta Sleep Inducing Peptide are demonstrated in rat studies and illustrate that DSIP provides significant pain relief [4].

Effects on metabolism

The metabolism of Delta Sleep Inducing Peptide was studied in hypoxic rats and was found to reduce stress-induced changes in mitochondrial monoamine oxidase A (MAO-A) activity and serotonin levels in the brains. In addition, Delta Sleep Inducing Peptide analogues were tested for their ability to counteract hypoxia-induced changes in MAO-A activity and serotonin content.

In rats, it has been shown that Delta Sleep Inducing Peptide reduces metabolic disturbances caused by stress, such as mitochondrial redox switching. The latter is inefficient and toxic. Acute hypoxia-response DSIP nasal spray shows potential to treat conditions like stroke and heart attack. DSIP nasal spray may also help prevent metabolic damage from oxygen deprivation by maintaining normal mitochondrial function.

These features make Delta Sleep Inducing Peptide a potent antioxidant that targets free radicals. Delta Sleep Inducing Peptide also protects mitochondrial function, reducing free radical production. This may make it an anti-ageing supplement, though more research is needed [5].

Chemical imbalances and depression

Clinical professionals began studying Delta Sleep Inducing Peptide and its effects on chemical imbalances after it was determined that it can alter mitochondrial activity in hypoxic conditions [6]. Latvia Researchers concluded that the inhibition of MAO-A and serotonin by DSIP nasal spray may influence the course of depression. Delta Sleep Inducing Peptide levels were found to be lower in depressed patients than in healthy control groups [7].

It has been proven that a peptide involved in improving the sleep cycle may also be useful to treat depression, because of the strong link between sleep and depression. Delta Sleep Inducing Peptide normalization has not been used to treat depression. The peptide has been linked to HPA axis (hypothalamic-pituitary-adrenal) changes and suicidal behaviour [8].


Although more Latvia research on the safety of DSIP nasal spray before the FDA can approve it for human consumption, animal studies have revealed that DSIP nasal spray has a plethora of potential benefits including being useful in pain relief, improving sleep patterns and quality. It can help regulate the body’s response to stress using cortisol production, as well as enhancing the LH and GH release.
