Chemical imbalance has long been identified as the leading cause of depression. According to a theory, people with low serotonin, dopamine, or norepinephrine levels are more likely to develop depression. Theoretically, increasing the number of hormones can treat depression. Researchers used selective serotonin reuptake inhibitors like Prozac and Zoloft, MAOIs, SNRIs, tricyclic antidepressants, and other medications to return norepinephrine and dopamine levels to normal. While initially successful, they eventually proved ineffective due to the unprecedented changes in the human system and other factors.

Chemical imbalance is not the only cause of depression. Irregular chemical regulation and signaling could also cause depression. As a result, doctors and scientists are working to find alternative treatments for depression.

Neuropeptides are a prime target because they are inextricably linked to various neuropsychiatric disorders. The findings of this study, which is still in its early stages, indicate that specific peptides are crucial and clinically efficient in treating depression and anxiety. This article will talk about the best peptides for depression.

The Best Peptides For Depression And Anxiety

The following peptides are required to combat depression and anxiety. They are Ghrelin, Pinealon, Semax, Selank, PE-22-28, Protirelin, DSIP, Oxytocin, and other hormones.

Oxytocin: Oxytocin is a peptide synthesized in the hypothalamus and secreted by the posterior pituitary gland. It is a neuropeptide that plays an essential role in anxiety and depression. According to research, Oxytocin administered intravenously can lessen the severity of depression and anxiety in people with Borderline Personality Disorder (BPD).

Pinealon: There is a clear link between sleep and depression, and Pinealon administration improves behavioral changes and positively impacts circadian rhythm disorders.

Pinealon also increases the expression of 5-tryptophan hydroxylase, an enzyme that significantly produces serotonin and can influence serotonin concentrations in the brain. In addition, the peptide reverses neuropsychiatric symptoms caused by sleep deprivation and sleep disorders.

Ghrelin: Ghrelin is a peptide that occurs naturally and has antidepressant properties.

High cortisol levels are a significant indicator of stress, anxiety, and depression, though it is unclear whether it is one of the causative agents. On the other hand, the peptide rises in response to elevated cortisol levels. Ghrelin reduces cortisol levels while preventing depression-like behavior and hypomotility.

Tryptophan is a neurotransmitter precursor that is involved in the pathophysiology of depression. Ghrelin removal alters tryptophan metabolism, according to research. Ghrelin derivatives such as GHRP-2 and GHRP-6 have comparable effects.

Selank: According to research, the inflammatory cytokine IL-6 plays an essential role in depression and anxiety. According to one study, IL-6 is an effective enhancer in patients with anxiety-asthenic disorder and other psychosomatic conditions characterized by symptoms such as fatigue, pain, headache, high blood pressure, and heart palpitations. IL-6 levels are higher in people with fibromyalgia, chronic fatigue syndrome, anxiety, or depression. Selank administration, on the other hand, suppresses the gene expression that regulates IL-6 production.

Semax: Depressed people have lower levels of brain-derived neurotrophic factors, according to research. Although it is unknown how BDNF levels cause depression, abnormal BDNF levels, and BDNF receptors have been linked to depression and suicidal behavior.

According to research, increasing BDNF levels can help treat depression. According to the study, semax can increase the stimulation of BDNF levels in the basal forebrain, lowering the prevalence of depression. Furthermore, scientists believe semax can aid in treating attention deficit hyperactivity disorder (ADHD).

Protirelin: Protirelin is a naturally occurring peptide hormone with anti-suicidal and anti-depressive properties produced in the hypothalamus. According to studies, Protirelin can reduce severe depression and suicidal ideation by 50% or more and is one of the best peptides for depression.

PE-22-28: PE-22-28 is the synthetic equivalent of Spadina, a naturally occurring peptide. The peptide is the most effective antidepressant with few or no side effects. PE-22-28 works by inducing neurogenesis to restore hippocampal volume and thus prevent depression.

Delta Sleep-Inducing Peptide (DSIP): DSIP is a neuropeptide with endocrine and physiological effects on the central nervous system. The peptide regulates corticotropin levels, reduces stress, prevents somatostatin production, keeps blood pressure stable, and influences sleep patterns.

DSIP also prevents changes in monoamine oxidase type A and serotonin levels, implying that the peptide may positively impact depression. Depression is associated with lower DSIP levels, according to research. However, as a peptide that regulates sleep, it has the potential to treat and manage depression. Furthermore, DSIP connects the hypothalamic-pituitary-adrenal axis and can modulate suicidal tendencies.

Finally, numerous research resources clarify how these peptides can be used to treat and manage depression and anxiety. Scientists are still looking for the best peptides for depression, anxiety, and other neuropsychiatric conditions with no side effects.
