The first bit of evidence that points to oxytocin as nature’s love glue comes from researchers who measured the hormone in couples. Psychology professor Ruth Feldman at Bar-Ilan University in Israel, spent years studying oxytocin’s role in the mother–child bond and recently decided to dive into the uncharted waters of romantic bonds by comparing oxytocin levels in new lovers and singles. “The increase in oxytocin during the period of falling in love was the highest that we ever found,” she says of a study she and her colleagues published in Psychoneuroendocrinology. New lovers had double the amount Feldman usually sees in pregnant women.
Our nutrition team created these easy mix-and-match menus using the same guidelines that helped 5-HTP dieters lose weight at top speed during the University of Rome study. The idea here is simple: You’ll eat balanced meals that keep you feeling energized and awesome, but you’ll also watch portions so you’re not overeating out of habit. While using these menus, be sure to drink plenty of water and add any other zero-cal beverages you like. You’re also encouraged to season meals to your liking with unlimited herbs, spices, vinegar, mustard, and citrus juice. As always, get a doctor’s OK before trying any new plan.
One way to clarify that question is to give individuals oxytocin rather than just measure naturally occurring levels. In experiments by couple therapist and researcher Beate Ditzen at the University of Zurich, couples each sprayed a liquid containing oxytocin up their noses (which ensures that the hormone reaches the brain). Ditzen then got them to talk with each other about an issue that both partners said often lead to disagreement or fighting, such as who did the housework or how they spent their free time. She observed how they communicated with each other during the discussion compared with couples who didn’t get the hormone.

Virtually all vertebrates have an oxytocin-like nonapeptide hormone that supports reproductive functions and a vasopressin-like nonapeptide hormone involved in water regulation. The two genes are always located close to each other (less than 15,000 bases apart) on the same chromosome and are transcribed in opposite directions. It is thought that the two genes resulted from a gene duplication event; the ancestral gene is estimated to be about 500 million years old and is found in cyclostomes (modern members of the Agnatha).[12]


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).
Thymosin beta 4, developed by RegeneRx Biopharmaceuticals as a pharmaceutical for the healing of wounds, is a synthetic version of the natural peptide. As Dr. Allan Goldstein emphasizes, “Tb4 represents a new class of wound healing compounds. It is not a growth factor or cytokine, but rather exhibits a number of physiological properties which include the ability to sequester and regulate actin, its potent chemotactic properties. . . and its capability to downregulate a number of inflammatory cytokines that are present in chronic wounds.” When a wound heals there are many growth factors produced in the area so that additional factors, such as those currently on the market for wound healing, may help but are not necessarily lacking. Tb4 treatment, however, adds a new dimension to wound repair by providing cells with actin as needed, for cell migration, replication and differentiation.
In a landmark 1979 study3, Cort Pedersen and Arthur Prange at the University of North Carolina in Chapel Hill showed that giving oxytocin to virgin rats could trigger maternal behaviours: the animals would build nests, lick or crouch over unfamiliar pups and even return lost pups to the nest. Researchers went on to show that oxytocin signalling in the brains of prairie voles (Microtus ochrogaster) helps the animals to form lifelong pair bonds4 — a rarity among mammals. In 2012, researchers even found a version of oxytocin in the tiny roundworm Caenorhabditis elegans, where it helps the animals find and recognize mates5.
Treated cells were washed with PBS and cytosolic protein extracts were prepared using 1X cell lysis buffer (Santa Cruz Biotechnology, CA) supplemented with protease inhibitor cocktail. Protein concentrations were determined using the Bradford assay (Bio-Rad, CA, USA) as per the manufacturer's protocol. Aliquots of protein lysates were separated on sodium dodecyl sulfate–10% polyacrylamide gels and Western blotting was performed. The proteins were transferred onto a polyvinylidene difluoride membrane (Bio-Rad, CA, USA) in transfer buffer (20 mm Tris, 150 mm glycine, 20% methanol, pH 8.0; TBS-T) at 4°C and 100 V for 1 hour. The membrane was blocked with 5% dry milk in TBS-T for 1 hour at room temperature and incubated with primary antibodies (1:1000) and horseradish peroxidase (HRP)-conjugated secondary antibodies. Protein bands were detected using an enhanced chemiluminescence (ECL) system (Amersham Biosciences, Backinghamshire, UK).

It should be noted that, anecdotally, 5-HTP is said to reduce cravings for carbohydrates in particular. The serotonergic (related to serotonin) system plays a role in macronutrient selection particular in obese persons with a craving for carbohydrates[13] and enhancing serotonergic transmission is known to reduce these cravings.[14] Beyond this, depressed serotonergic tranmission (hypothalamus) is also implicated in increased eating and reduced satiety in general.[15]
It would have been interesting if Bartz had asked about *both* parents’ parenting styles. (Spoken by a guy writing a book on fathers.) It would have been easy enough; just add another question. Any differences between perceptions of mothers and fathers might have been illuminating. But, as in so much family research, fathers were once again ignored or excluded. (As if fathers don’t have parenting styles…)

5-HTP appears to reduce food intake secondary to increasing satiety, although most studies are currently conducted in women (in regards to 5-HTP being related to serotonin, this may be relevant; see our creatine page and the Depression section for more information). At least one study that was mixed gender supports the notion it benefits both genders, however
We have evaluated the efficacy of early Tβ4 treatment on spatial learning and sensorimotor functional recovery in rats after TBI induced by unilateral CCI.34 In brief, TBI rats received Tβ4 at a dose of either 6 or 30 mg/kg (RegeneRx Biopharmaceuticals Inc, Rockville, MD) or a vehicle control (saline) administered i.p. starting at 6 hours after injury and then at 24 and 48 hours. Spatial learning was performed during the last five days (31-35 days post injury) using the modified Morris water maze (MWM) test, which is extremely sensitive to the hippocampal injury.35-37 Tβ4-treated TBI rats showed significant improvement in spatial learning when compared to the saline-treated TBI rats. Tβ4 treatment also significantly reduced the swim latency to reach the hidden platform by rats post TBI compared to saline treatment. Using the modified Neurological Severity Score (mNSS) test, our data show that significantly improved scores were observed after TBI in the Tβ4-treated group compared to the saline-treated group. Our data also show that Tβ4 reduced the incidence of both right forelimb and hindlimb footfaults in TBI rats.34 Histological data show that early Tβ4 treatment reduced cortical lesion volume by 20% and 30% for 6 mg/kg and 30 mg/kg, respectively, and reduced hippocampal cell loss. These findings suggest that TB4 provides neuroprotection even when the treatment was initiated 6 hours post injury. In addition, 6-hour Tβ4 treatment promotes neurogenesis in the dentate gyrus (DG) of the hippocampus,38 which may contribute to improvement in spatial learning.
Cells were incubated with 200 μM H2O2 for indicated times (A). Cells were pretreated with indicated concentrations of Tβ4 peptide (0.1–5 μg/mL) for 2 hours and then incubated with 200 μM H2O2 for 60 minutes (B). Data were representative of three independent experiments. The bar graph shows the fold increase in protein expression compared with control cells * Statistically significant differences compared with the control, p<0.05. # Statistically significant difference compared with the H2O2—treated group.

We think that the most important region is the nucleus accumbens, which is kind of up here. The nucleus accumbens is where we can measure a release of the neurotransmitter dopamine when humans or animals take drugs or are exposed to other rewarding stimuli, such as sex. Or gambling, for example, or monetary reward activates the nucleus accumbens as well.
Thymosin is a hormone secreted from the thymus. Its primary function is to stimulate the production of T cells, which are an important part of the immune system. Thymosin also assists in the development of B cells to plasma cells to produce antibodies. The predominant form of thymosin, thymosin b4, is a member of a highly conserved family of actin monomer-sequestering proteins. b-thymosins are the primary regulators of unpolymerized actin, and are essential for maintaining the small cytoplasmic pool of free G-actin monomers required for rapid filament elongation and allowing for the flux of monomers between the thymosin-bound pool and F-actin.
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]
Young says that the oxytocin field would benefit from closer collaboration between basic and clinical researchers. If basic scientists can work out how oxytocin helps the brain to process social stimuli, then that might help in the design of stimuli — in the form of behavioural therapies — that could be given alongside the hormone to change behaviour, just as oxytocin and pup calls together affect virgin mice. “I think in the future these two branches need to have more communication,” Young says.
I’ve been on this stuff for lots of years. I really needed it when I was depressed like hell, and I had an emotional pain that simply didn’t go away for 2 decades prior to starting that stack. Did it help? yes. Was it the best intervention possible? probably not. I was able to get off all this stuff with the uridine stack, and I believe it partly fixed a part of my brain that was damaged from this decade long suffering. So this is, why I am now more into brain regeneration and psychotherapeutic interventions (even though I do them myself), and I would only go back to this stack if I was completely fucked up again. There are a lot of side effects, and its a fine line to balance the supplements, to get rid of the side effects…

Establishment of maternal behavior: Successful reproduction in mammals demands that mothers become attached to and nourish their offspring immediately after birth. It is also important that non-lactating females do not manifest such nurturing behavior. The same events that affect the uterus and mammary gland at the time of birth also affect the brain. During parturition, there is an increase in concentration of oxytocin in cerebrospinal fluid, and oxytocin acting within the brain plays a major role in establishing maternal behavior.
Bromodeoxyuridine (BrdU), a thymidine analogue, can be incorporated into the DNA of dividing cells and is widely used to label new cells.61-63 To label proliferating cells, BrdU (100 mg/kg) was injected i.p. daily starting at day 1 post TBI for 10 days. The number of BrdU-positive cells found in the ipsilateral cortex, DG, and CA3 areas was significantly increased 35 days after TBI compared with sham controls.18,34,64,65 Tβ4 treatment further increased the number of BrdU-positive cells compared to saline controls.34 The increased number of BrdU-positive cells may result from effects of Tβ4 on either increasing cell proliferation or reducing cell death of newborn cells. Our recent data show Tβ4 increases oligodendrocyte precursor cell proliferation and differentiation in animal models of stroke25 and experimental autoimmune encephalomyelitis.27 Tβ4 may not directly affect cell proliferation but inhibit cell death, for example, in corneal and conjunctival epithelial cells treated with benzalkonium chloride in vitro66 and endothelial precursor cells under serum deprivation.67 Our data further show that neurogenesis increases in TBI rats treated with Tβ4, suggesting that Tβ4 promotes newborn cells to differentiate into neurons. This is consistent with the effect of Tβ4 on promoting epicardium-derived progenitor cell differentiation into endothelial and smooth muscle cells to form the coronary vasculature.22 Whether the increased number of BrdU-positive cells in the brain of TBI rats treated with Tβ4 is tissue specific remains unknown. Tβ4 may not directly affect cell proliferation. Increased cell proliferation and neurogenesis are also possibly secondary to that Tβ4-mediated angiogenesis, as described later.
A number of factors can inhibit oxytocin release, among them acute stress. For example, oxytocin neurons are repressed by catecholamines, which are released from the adrenal gland in response to many types of stress, including fright. As a practical endocrine tip - don't wear a gorilla costume into a milking parlor full of cows or set off firecrackers around a mother nursing her baby.
Uterine contractions. These are important for cervical dilation before birth and causes contractions during the second and third stages of labor. Oxytocin release during breastfeeding causes mild but often painful uterine contractions during the first few weeks of lactation. This also serves to assist the uterus in clotting the placental attachment point postpartum. However, in knockout mice lacking the oxytocin receptor, reproductive behavior and parturition is normal.16

Oxytocin is a versatile actor, whose resume includes all sorts of jobs in sex, reproduction, social behaviour and emotions.  It can increase trust among people and make them more cooperative (this works in meerkats, too). It can increase the social skills of autistic people. It’s released during orgasm. It affects lactating breasts, contracting wombs and the behaviour of sheep mothers towards their newly born lambs. The list goes on: drug addiction, generosity, depression, empathy, learning, memory.
The RANKL and OPG have been identified as a key regulatory component of alveolar bone loss associated with inflammatory periodontal disease [52]. Moreover, PDLCs were shown to express several osteoclastogenic cytokines, including both OPG and RANKL [30, 31]. Our data demonstrated that Tβ4 peptide abolished H2O2-induced RANKL expression and restored OPG expression. Osteoclasts, bone-resorptive multinucleated cells derived from hematopoietic stem cells, are associated with osteolytic diseases. Furthermore, NFATc1, a master modulator of osteoclastogenesis, regulates target genes, such as cathepsin K and calcitonin receptor or Calcr [53]. In our in vitro study using BMMs, Tβ4 peptide directly and indirectly inhibited RANKL-induced osteoclast differentiation and expression of osteoclast markers, such as cathepsin-K, calcitonin receptor or Calcr, NFATc1, and RANK in BMM cells. These results indicated that Tβ4 was a key therapeutic target in controlling inflammation-induced bone loss.

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]

Melanotan II non-selectively mimics the action of melanocortin peptides. These are natural hormones involved with pigmentation, energy homeostasis, sexual functioning, the immune system, inflammation, and the cardiovascular system. Much like melanotan I (afamelanotide), melanotan II stimulates the production of eumelanin, causing the skin to go darker (tanning).

"There was no substance labelled unfit for human use so anyone that tries to bandy that comment around apart from the fact the comment is totally false, we are now starting to accrue our legal case against people that have suggested as such. Under no circumstances was anything ever injected or given to a player which was unfit for human consumption," Dank told ABC News Radio on Sunday.
