Oxytocin and vasopressin are the only known hormones released by the human posterior pituitary gland to act at a distance. However, oxytocin neurons make other peptides, including corticotropin-releasing hormone and dynorphin, for example, that act locally. The magnocellular neurosecretory cells that make oxytocin are adjacent to magnocellular neurosecretory cells that make vasopressin. These are large neuroendocrine neurons which are excitable and can generate action potentials.[124]
Maternal behavior: Female rats given oxytocin antagonists after giving birth do not exhibit typical maternal behavior.[59] By contrast, virgin female sheep show maternal behavior toward foreign lambs upon cerebrospinal fluid infusion of oxytocin, which they would not do otherwise.[60] Oxytocin is involved in the initiation of maternal behavior, not its maintenance; for example, it is higher in mothers after they interact with unfamiliar children rather than their own.[61]
100mg works well for mood and getting to sleep. Put 100mg in my Pre Workout Powder (Non Stimulant). Don't know if anyone else has tried this or if it was just a coincidence but it made the weights feel considerably lighter and I was able to use more weight than I have in a decade. I will definitely be trying that again. I also cut the bag open and emptied it into an old pill bottle through a small funnel. No wastage. Easy.
MAPKs and NF-κB played pivotal roles in the development of osteoclasts downstream of RANK signaling [54]. In this study, we demonstrated that Tβ4 activation by Tβ4 peptide inhibited RANKL-induced p38, ERK, JNK MAPK, and NF-κB signaling pathways. These results suggested that Tβ4 activation might inhibit osteoclast differentiation via inhibition of the signaling cascades MAPK/NF-κB/NFATc1.

How not surprising on one level that a hormone involved in the formation of primary bonds, those that can have serious impacts on your survival, would be discerning. After all, if you had a mother who was dangerous, abusive, etc., how counter productive would it be for you to bond so tightly to her that you were all over her all the time, increasing your chances of pissing her off and killing you. And, how beneficial for you to be more bonded to a mother figure who was good to you, and provided you with nurture.

Social behavior[66][111] and wound healing: Oxytocin is also thought to modulate inflammation by decreasing certain cytokines. Thus, the increased release in oxytocin following positive social interactions has the potential to improve wound healing. A study by Marazziti and colleagues used heterosexual couples to investigate this possibility. They found increases in plasma oxytocin following a social interaction were correlated with faster wound healing. They hypothesized this was due to oxytocin reducing inflammation, thus allowing the wound to heal more quickly. This study provides preliminary evidence that positive social interactions may directly influence aspects of health.[112] According to a study published in 2014, silencing of oxytocin receptor interneurons in the medial prefrontal cortex (mPFC) of female mice resulted in loss of social interest in male mice during the sexually receptive phase of the estrous cycle.[113] Oxytocin evokes feelings of contentment, reductions in anxiety, and feelings of calmness and security when in the company of the mate.[101] This suggests oxytocin may be important for the inhibition of the brain regions associated with behavioral control, fear, and anxiety, thus allowing orgasm to occur. Research has also demonstrated that oxytocin can decrease anxiety and protect against stress, particularly in combination with social support.[114] It is found, that endocannabinoid signaling mediates oxytocin-driven social reward.[115]
5-HTP, along with other L-Tryptophan supplements, have been implicated in the flu-like, potentially fatal Eosinophilic Myalgia Syndrome. This syndrome was initially tied to  impurities - Amino Acids called "Peak E" and "Peak X" - which were present in these products because of poor manufacturing processes by a single major supplier. Some people reject this idea and believe that the syndrome is caused by an excess of tryptophan itself (10, 11).
Its unique potential as a healing substance lies in that it interacts with cellular actin and regulates its activity. Tb4 prevents actin from assembling (polymerizing) to form filaments but supplies a pool of actin monomers (unpolymerized actin) when a cell needs filaments for its activity. A cell cannot divide if actin is polymerized. Tb4 therefore serves in vivo to maintain a reservoir of unpolymerized actin that will be put to use when cells divide, move and differentiate.
Autism: Oxytocin has been implicated in the etiology of autism, with one report suggesting autism is correlated with genomic deletion of the gene containing the oxytocin receptor gene (OXTR). Studies involving Caucasian and Finnish samples and Chinese Han families provide support for the relationship of OXTR with autism.[55][56] Autism may also be associated with an aberrant methylation of OXTR.[55]
Dr Sohère Roked is a GP in the UK with a specialist interest in integrative medicine. She prescribes 5-HTP to patients with anxiety and depression, alongside vitamins and other natural supplements, and sees no problem with it being used for mild conditions. "With the patients I see, generally I've seen good results with it. Antidepressants do work for some people, so I'm not against them completely, but others don't want to go down that path straight away. This gives them another option."
In humans, the Tβ4 gene TMSB4X is localized to the X chromosome at Xq21.3–q22 (). The Tβ4 cDNA open reading frame contains an initial methionine codon followed by a codon for the N-terminal serine and, although cells secrete a certain amount of Tβ4, there is no hydrophobic signal sequence. The initial methionine residue of the nascent Tβ4 polypeptide is removed and the N-terminal serine residue is often acetylated in the cells.

You can't purchase oxytocin spray at any retail outlet and as our experts made clear in the program, buying a product online gives you no guarantee of what is actually in the product - it could be oxytocin or it could be something else - nor is it proven that the spray will actually reach your brain. For these reasons, none of our experts recommend purchasing oxytocin spray.
Thymosins were discovered in the mid 1960’s, when Allan Goldstein from the Laboratory of Abraham White at the Albert Einstein College of Medicine in New York studied the role of the thymus in development of the vertebrate immune system. Since then, Dr. Goldstein founded a company that creates thymosin alpha 1 for the purpose of increasing immune cell activity, and thymosin beta 4 (TB-500) to promote wound repair and healing.
Injected oxytocin analogues are used to induce labour and support labour in case of non-progression of parturition. It has largely replaced ergotamine as the principal agent to increase uterine tone in acute postpartum haemorrhage. Oxytocin is also used in veterinary medicine to facilitate birth and to increase milk production. The tocolytic agent atosiban (Tractocile®) acts as an antagonist of oxytocin receptors; this drug is registered in many countries to suppress premature labour between 24 and 33 weeks of gestation. It has fewer side-effects than drugs previously used for this purpose (ritodrine, salbutamol and terbutaline).

Increasing trust and reducing fear. In a risky investment game, experimental subjects given nasally administered oxytocin displayed "the highest level of trust" twice as often as the control group. Subjects who were told that they were interacting with a computer showed no such reaction, leading to the conclusion that oxytocin was not merely affecting risk-aversion.[18] Nasally administered oxytocin has also been reported to reduce fear, possibly by inhibiting the amygdala (which is thought to be responsible for fear responses).[19] There is no conclusive evidence for access of oxytocin to the brain through intranasal administration, however.

Potential side effects of 5-HTP include heartburn, stomach pain, nausea, vomiting, diarrhea, drowsiness, sexual problems, vivid dreams or nightmares, and muscle problems.[19] Because 5-HTP has not been thoroughly studied in a clinical setting, possible side effects and interactions with other drugs are not well known. According to the US National Institute of Health TOXNET, 5-HTP has not been associated with serotonin syndrome or any serious adverse events in humans.[20] Across multiple studies, 5-HTP also been reported to not cause any noticeable hematological or cardiovascular changes.[21] 5-HTP also has not been associated with eosinophilia.[22]
