What is DSIP peptide?

Delta sleep-inducing peptide (DSIP) is a substance that naturally appears in the organism, which was firstly isolated from the rabbit brain in 1977. This interesting peptide is a nonapeptide that is usually synthesized in the hypothalamus and targets multiple sites, including ones within the brainstem. As it can be figured out by its name, DSIP encourages sleep and this fact has been proved in laboratory subjects, such as rabbits, mice, rats, and also cats. As a matter of fact, DSIP encourages a certain kind of sleep which is characterized by an enhancement in the delta rhythm of the EEG.

DSIP is usually found in minute amounts in the bloodstream. Brain and plasma DSIP concentrations demonstrate a marked diurnal variation and it has been revealed to be a link between DSIP plasma concentrations and circadian rhythm in human organisms.

How does DSIP peptide work?

If we compare DSIP peptide with other peptides, DSIP is distinct in the way that it possesses the ability to migrate freely across the blood–brain barrier and is absorbed from the gut without being denatured by enzymes. This peptide can be found in moderately increased concentrations in the milk produced by humans. 

Unfortunately, there is not much scientific evidence regarding this peptide, but if you have a license and are working in the lab, you can Purchase DSIP USA and conduct your own studies on the matter and help widen the field of information on this topic.

What are the benefits of DSIP peptide?

  1. Lowers basal corticotropin level and obstructs its release.
  2. Promotes the release of luteinizing hormone (LH).
  3. Promotes the release of somatoliberin and somatotrophin secretion and obstructs somatostatin secretion
  4. Has the ability to regulate blood pressure and myocardial contraction.
  5. It has been proved to possess anticarcinogenic attributes.
  6. Has an antihypertensive effect
  7. Possess antimetastatic activity
  8. Reduces amphetamine-induced hyperthermia
  9. May be beneficial in chronic pain conditions 
  10. Has potent anticancer properties

DSIP effects in chronic pain

A pre-clinical trial has revealed that DSIP peptide can greatly decrease the perception of pain and can also improve mood. The same investigation has shown that DSIP can be utilized in treating patients with psychological dependence on other types of pain medications, due to the fact that it aids in the process of decreasing withdrawal effects and the pain rebound that usually appears after cessation of long-term analgesic therapy.

DSIP effects on  metabolism

Research conducted on lab subjects has revealed that DSIP modifies the metabolic disturbances induced by stress, which are often found to cause the shift of mitochondria from oxygen-depended respiration to oxygen-independent respiration. By maintaining a normal function of the mitochondria, DSIP could possess the ability to set off the metabolic damage caused by oxygen deprivation. 

DSIP effects of depression and chemical imbalances

After developing multiple studies, researchers have found out that DSIP obstructs modifications in monoamine oxidase type A and serotonin levels, which means that this peptide could have an impact on the course of depression. This was discovered by analyzing the cerebrospinal fluid of patients suffering from depression. These studies revealed that a patient with depression has lower levels of DSIP compared to controls. Taking into consideration the significant connection between depression and sleep, it may come as no surprise that the peptide responsible for regulating sleep cycles could also play a valuable role in the development of depression.
