Recent reports have stated that inhibitors of Wnt signaling have emerged as promising strategies for bone disease and inflammatory diseases [26, 55]. Wnt5a, one of the most common Wnt molecules that activate the non-canoical pathway, binds to Fzd and its co-receptor, Ror2 [56]. In synoviocytes from rheumatoid arthritis patients, the expressions of Wnt5a and Frizzled5 (Fzd5) were significantly enhanced [25] and their blockades inhibited synoviocyte activation [55]. Recently, Wnt5a was highly expressed in synovial tissues in a mouse model of rheumatoid arthritis where inhibition of Wnt5a-Ror2 signaling suppressed bone loss [57]. Our data demonstrated that ROS up-regulated Wnt5a and its cell surface receptors, Frizzled and Ror2, as well as mRNA and protein expressions in time- and dose-dependent manners in PDLCs.
Research shows that co-administration with carbidopa greatly increases plasma 5-HTP levels.[46] However, several studies have reported that 5-HTP is effective even without a peripheral decarboxylase inhibitor (e.g. carbidopa).[47][unreliable medical source?] Other studies have indicated the risk of a scleroderma-like condition resulting from the combination of 5-HTP and carbidopa.[48]

Affecting generosity by increasing empathy during perspective taking. In a neuroeconomics experiment, intranasal oxytocin increased generosity in the Ultimatum Game by 80% but has no effect in the Dictator Game that measures altruism. Perspective-taking is not required in the Dictator Game, but the researchers in this experimental explicitly induced perspective-taking in the Ultimatum Game by not identifying to participants which role they would be in.13
I am not a doctor and this is not to be taken, interpreted or construed as medical advice. Please talk with a licensed medical professional about this. I would say yes though. Just because you dont “know” or “feel” any injury, you might be one functional movement away from a weakened tendon or muscle – snap, crackle and POP! These are just my own personal thoughts and not a prescription or a diagnosis or any form of health care whatsoever.
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]
The combination of supplemental 5-HTP and a dopamine decarboxylase inhibitor is also thought to reduce the risk for cardiovascular complications, as excess serum (but not neural) serotonin is associated with heart valve disease in rats.[56] Due to the accumulation of 5-HTP in neural tissue following the combination[54] it is plausible to assume a reduction in systemic serotonin; this has not been demonstrated yet, however.
In this study, Tβ4 mRNA down-regulation was detected in in vitro in PDLCs stimulated with the ROS. This down-regulation of Tβ4 was also observed in GCF of periodontitis patient [19] and endotoxin-induced septic shock of rats [39]. ROS were generated predominantly by polymorphonuclear leukocytes (PMN) during an inflammatory response and involved in tissue destruction associated with periodontal diseases [40]. Thus, we chose to use ROS-stimulated PDLCs in this study since ROS, such as superoxide and H2O2, have been proposed as key players in bone resorption [41] and implicated in the pathogenesis of rheumatoid arthritis and periodontitis [29].
Because of its role in creating serotonin, 5-HTP is indirectly involved in producing melatonin, a hormone that is critical for sleep. Melatonin helps the body’s bio clock stay in sync, and regulates daily sleep-wake cycles. A strong bio clock and regular sleep-wake routines are the cornerstone of healthy, restful, rejuvenating sleep. Research suggests that 5-HTP may help shorten the time it takes to fall asleep and increase sleep amounts.
The uterine-contracting properties of the principle that would later be named oxytocin were discovered by British pharmacologist Sir Henry Hallett Dale in 1906,[125][46] and its milk ejection property was described by Ott and Scott in 1910[126] and by Schafer and Mackenzie in 1911.[127] In the 1920s, oxytocin and vasopressin were isolated from pituitary tissue and given their current names. The word oxytocin was coined from the term oxytocic, Greek ὀξύς, oxys, and τοκετός , toketos, meaning "quick birth".
At SelfHacked, it’s our goal to offer our readers all the tools possible to get optimally healthy. When I was struggling with chronic health issues I felt stuck because I didn’t have any tools to help me get better. I had to spend literally thousands of hours trying to read through studies on pubmed to figure out how the body worked and how to fix it.
The scientists discovered that oxytocin strengthens negative social memory and future anxiety by triggering an important signaling molecule -- ERK (extracellular signal regulated kinases) -- that becomes activated for six hours after a negative social experience. ERK causes enhanced fear, Radulovic believes, by stimulating the brain's fear pathways, many of which pass through the lateral septum. The region is involved in emotional and stress responses.
RegeneRx is continuing with pre-clinical research, in collaborative arrangements with the National Institutes of Health, accumulating data on the effects of Tb4 and aiming for an IND application (Investigational New drug App-lication) to proceed with clinical studies. Phase I clinical trials will determine the ability of Tb4 to repair ulcers in diabetic patients and to reduce inflammation and accelerate recovery from burns and abrasions to the cornea.

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.
Romantic attachment: In some studies, high levels of plasma oxytocin have been correlated with romantic attachment. For example, if a couple is separated for a long period of time, anxiety can increase due to the lack of physical affection. Oxytocin may aid romantically attached couples by decreasing their feelings of anxiety when they are separated.[101]
Supplements haven't been tested for safety and due to the fact that dietary supplements are largely unregulated, the content of some products may differ from what is specified on the product label. Also keep in mind that the safety of supplements in pregnant women, nursing mothers, children, and those with medical conditions or who are taking medications has not been established. You can get tips on using supplements, but if you're considering the use of 5-HTP supplements, talk with your primary care provider first. Self-treating a condition and avoiding or delaying standard care may have serious consequences.

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.

Although obtaining Melanotan II and Bremelanotide is relatively easy to do, both substances come in powder form and then must be reconstituted using sterile water prior to subcutaneous injection—a method of administration that can cause lead to skin bruising, cross-contamination, or infection, if the person performing the injection is inexperienced and the syringe isn't clean.
One study investigating romantic stress that looked at nondepressed youth who went through a recent breakup and were given 60mg of Griffonica Simplicifonia (12.8mg 5-HTP) twice a day for 6 weeks in an open-label study noted reductions in percieved romantic stress when measured at the 3 week mark with no further improvement at 6 weeks; there was no control nor placebo group in this study.[29]

Oxytocin is typically remembered for the effect it has on prosocial behaviors, such as its role in facilitating trust and attachment between individuals. Consequently, oxytocin is often referred to as the “love hormone".[73][qualify evidence] However, oxytocin has a more complex role than solely enhancing prosocial behaviors. There is consensus that oxytocin modulates fear and anxiety; that is, it does not directly elicit fear or anxiety.[74] Two dominant theories explain the role of oxytocin in fear and anxiety. One theory states that oxytocin increases approach/avoidance to certain social stimuli and the second theory states that oxytocin increases the salience of certain social stimuli, causing the animal or human to pay closer attention to socially relevant stimuli.[75]
“L-5-Hydroxytryptophan significantly reduced the reaction to the panic challenge in panic disorder patients, regarding subjective anxiety, panic symptom score and number of panic attacks, as opposed to placebo. No such effect was observed in the healthy volunteers. L-5-Hydroxytryptophan acts to inhibit panic, which supports a modulatory role of serotonin in panic disorder.”
Despite this, Tβ4’s place on the banned-substances list is warranted. It reflects the possibility that the effects of the supplement may manifest as a tangible improvement in athletes. However, any time a journalist flippantly declares it “heals damaged tissue and speeds recovery”, it should be noted that such claims are a harmful distortion of the facts.
To untangle the ways different hormones together influence behavior in more naturalistic contexts, we worked with the Tsimane people in Bolivia. Traditional societies like the Tsimane are not living relics of the past, but their lifeways – small, tight-knit communities that produce their own food – can reveal the kinds of situations our hormone systems are well adapted to.
The oxytocin peptide is synthesized as an inactive precursor protein from the OXT gene.[18][19][20] This precursor protein also includes the oxytocin carrier protein neurophysin I.[21] The inactive precursor protein is progressively hydrolyzed into smaller fragments (one of which is neurophysin I) via a series of enzymes. The last hydrolysis that releases the active oxytocin nonapeptide is catalyzed by peptidylglycine alpha-amidating monooxygenase (PAM).[22]
5-HTP is sold over the counter in the United States, Canada, the Netherlands, and the United Kingdom as a dietary supplement for use as an antidepressant, appetite suppressant, and sleep aid. It is also marketed in many European countries for the indication of major depression under the trade names Cincofarm, Levothym, Levotonine, Oxyfan, Telesol, Tript-OH, and Triptum.[1]
