Despite these many roles, oxytocin is often reduced to a misleading label. While “hormone of love” may be great for catchy headlines and compelling marketing slogans, they are ultimately misleading. Jennifer Bartz from the Mount Sinai School of Medicine has found that oxytocin can have completely opposite effects on the way people behave, depending on how they view their relationships to other people.
Even if you did look after yourself adequately and monitor the amount of 5-HTP you were taking, it doesn't appear to be a permanent or lasting solution. A couple of the doctors talked about something that comes up time and time again with long-term SSRI use: a dissipating effect, meaning they can feel less and less effective over time. It seems that people may have the same problem with 5-HTP. "If you push on your biochemistry hard enough, it may downregulate," Dr Paddock explained. "If you're taking SSRIs your body may downregulate the amount of serotonin it puts out so you get waning effects over time. It's similar with 5-HTP. There may be a certain level of serotonin your body is keeping you at and if you raise it or push it, your body then may say, 'Okay, we're above the set point, let's then raise that point again.'"
I was just diagnosed with achilles tendonosis in both of my achilles. I am an avid lifter as well as city leagues for football and basketball, I live in Montana so I hike a lot and participate In obstacle course races. My achilles have ground me to a halt over the last 3 months months. I have been referred to a surgeon for a Tenex procedure on both achilles. I am only 32 the last thing I want is have both of my achilles cut into. I’m looking at the TB-500 and BPC-157 to hopefully avoid surgery. I have done my research but am getting conflicting numbers as far as dosing. I am roughly 240 pounds and 6’5 could u recommend a dosage and cycle? Also I was wondering where the most effective injection site would be? Do I need it directly into the achilles itself or is local good enough?
Oxytocin is not only correlated with the preferences of individuals to associate with members of their own group, but it is also evident during conflicts between members of different groups. During conflict, individuals receiving nasally administered oxytocin demonstrate more frequent defense-motivated responses toward in-group members than out-group members. Further, oxytocin was correlated with participant desire to protect vulnerable in-group members, despite that individual's attachment to the conflict.[64] Similarly, it has been demonstrated that when oxytocin is administered, individuals alter their subjective preferences in order to align with in-group ideals over out-group ideals.[65] These studies demonstrate that oxytocin is associated with intergroup dynamics. Further, oxytocin influences the responses of individuals in a particular group to those of another group. The in-group bias is evident in smaller groups; however, it can also be extended to groups as large as one's entire country leading toward a tendency of strong national zeal. A study done in the Netherlands showed that oxytocin increased the in-group favoritism of their nation while decreasing acceptance of members of other ethnicities and foreigners.[66] People also show more affection for their country's flag while remaining indifferent to other cultural objects when exposed to oxytocin.[67] It has thus been hypothesized that this hormone may be a factor in xenophobic tendencies secondary to this effect. Thus, oxytocin appears to affect individuals at an international level where the in-group becomes a specific "home" country and the out-group grows to include all other countries.

On a personal note, 5-HTP is actually one of the 1st nootropics I ever used. When I was a teenager and would go to raves me and my friends would use 5-HTP the next day because ecstasy (MDMA) diminishes the serotonin levels. Anyone with much experience with ecstasy knows that the day(s) after can be pretty hellish because the drug so depletes your feel good neurotransmitters, 5-HTP is sort of a Biohack for this.

Since Wnt5a expression is associated with rheumatoid arthritis and periodontitis [25, 26], expression of Wnt5a and its cell surface receptors, Frizzled and receptor tyrosine kinase-like orphan receptor 2 (Ror2), were examined. As shown in Fig 9A–9D, mRNA and protein expressions of Wnt5a and its receptors were increased by H2O2 in a time- and dose-dependent manner.
High and low oxytocin levels are possible, but research has not yet found any implications of these conditions. Men with high levels of oxytocin sometimes develop benign prostatic hyperplasia, or the enlarging of the prostate gland. This condition can cause urinary complaints. A lack of oxytocin can prevent the milk letdown reflex and make breastfeeding difficult. Low oxytocin levels have also been linked to depression, but using oxytocin to treat mental health conditions has not yet been studied sufficiently.
Guastella and his team just completed an unpublished study that is the first to test the effects of oxytocin on couples in therapy. In one part of the study, couples were asked to discuss a “hot topic,” one that usually led to conflict between the pair, and to then try to solve the issue. Although the data analysis is still in progress, Guastella expects couples that got oxytocin to show less hostile interpretations of the problem and be less critical of their partners. He thinks overall it will increase perspective-taking and reduce blame, leading to smoother communication and better problem-solving.
Wonderful column. My expertise is the psychology of risk perception, and I have done some reading on oxytocin and trust (not the kind you want to boost in a bar with Liquid Trust – you can the stuff with pheromones – to boost THAT kind of trust). It turns out there is a high concentration of oxytocin receptors on the amygdala, the area of the brain where fear starts. As oxytocin levels go up, the ability of the amygdala to be warry and more mistrustful goes down. I describe this in Ch. 3 of How Risky Is It, Really? Why Our Fears Don’t Always Match the Facts. A few graphs of which are below. I wonder whether the influence of oxytocin on the amygdala might be connected with the finding of the study you write about.

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.[20]
First, dietary supplements are not regulated as drugs in the US, and the careful testing and quality control that are required of prescription drugs do not apply to supplements like 5-HTP. This is why serious adverse effects and major outbreaks, like the one associated with tryptophan, can occur. You can minimize this risk by using only USP-Verified supplements.
In 19 obese females given either placebo or 8mg/kg (weight not actually given, only BMI between 30-40 for women) daily for 5 weeks without any concurrent dietary recommendations, 5-HTP treatment was associated with a decrease in appetite and food intake (resulting in weight loss) without significantly affecting mood state.[9] This study noted that food intake was reduced from an average of 2,903kcal to 1,819kcal (62% of baseline) while placebo only reduced calories to 80%, and the 0.5kg weight loss in placebo was outperformed by a near 1.5kg loss in 5-HTP. These weight loss effects have been noted with 750mg 5-HTP over 2 weeks in overweight diabetics[10] and over 12 weeks in obese persons given 900mg 5-HTP daily (58% of baseline intake); this latter study had a 6 week trial without a diet (in which significant weight loss was only noted at week 6) followed up by coadministration with a diet where weight loss proceeded to reach an additional 3.3kg over the subsequent 6 weeks;[11] this latter study is duplicated in Medline.[12]

I was in a bad accident 5 years ago and was feeling better until my Dr. gave me levaquin which damages your mitochondria, gut, tendons And ligaments. I was going to order BPC 157 but see where you think TB500 is stronger. Do you know if it shows up on an employee drug test as i get tested occasionally? Also, your thoughts on fragment 176-191, a friend of mine uses it and suggested it for me. I understand you’re not a Dr, but just looking for your personal opinion. Thank you

When stressed, individuals become mentally and emotionally overwhelmed quite easily. Although individuals can quickly experience the effects of stress on their mental well-being, physical health is also at risk. Some stress is normal. However, chronic stress levels can increase the risk of heart disease and other serious health complications. Regardless of your personal stressor, it is critical to try managing rising stress levels to protect your current and future health. The following highly effective methods will help everyone unwind and promote a more positive state of mind.

Don’t take it by itself, you want to take it with a meal. The half life seems to vary; some people just need to take a single dose daily whereas some break it up into several doses. The dosage range is pretty wide, from 50 to 900 milligrams. Many report the antidepressant effect desired from lower doses, so start low with this one. Do not use a liquid form of 5-HTP.

But like most peptides on the market, TB-500 has limited long term studies involving human use. Although I haven’t personally used TB-500 (I can’t, since I compete in WADA sanctioned sports like triathlon and obstacle course racing), from what I’ve seen and heard from bodybuilders and athletes using the peptide, the primary side effect is a temporary sense of lethargy. Also, some people report getting a head rush when injecting TB-500, but report this head rush goes away a few minutes after injecting.
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).
Oxytocin production is controlled by a positive feedback mechanism. This mechanism allows the release of the oxytocin hormone when a trigger occurs. The hormone then causes an action in the body, such as the letdown of milk or the start of labor contractions, which signals more production of oxytocin. The feedback cycle continues until the action, such as childbirth or feeding the baby, is complete.
For this study, one of us, Ben Trumble, followed Tsimane men as they went hunting for food. Typically, Tsimane men set out alone or with a partner in the early morning and search in the forest for prey such as wild pigs, deer, monkeys, or the rare tapir. Following long looping trails they might be gone for eight or nine hours, traveling about six miles (ten kilometers). Ben collected saliva samples throughout the hunt in order to measure changes in men’s hormone levels.
Animal studies have found high levels of both stress and oxytocin in voles that were separated from other voles. However, when the voles were given doses of oxytocin, their levels of anxiety, cardiac stress, and depression fell, suggesting that stress increases internal production of the hormone, while externally supplied doses can help reduce stress.

In November 2008, the UK Medicines and Healthcare products Regulatory Agency (MHRA) warned the public against melanotan use stating it was an unlicensed medicine that may not be safe. As such, it is illegal to market or supply this product in the UK due to its unlicensed nature. Additionally the MHRA warned 18 companies about selling or advertising the product and closed down 72 websites involving melanotan. By 2013, the MHRA had received 18 reports of 74 separate reactions to the products and reactions have involved stomach and heart problems, as well as blood and eye disorders.


Expanding upon the possible anti-panic effects of 5-HTP, one study using 2mg/kg 5-HTP to children (3.2-10.6 years of age) at bedtime for 20 days noted that 5-HTP was asssociated with beneficial response (more than 50% reduction in night terror frequency) of 93.5% of children relative to 28.6% in placebo.[42] Oddly, 6 months after the initial supplementation period the 5-HTP group still reported less sleep terrors (83.9% reporting improvement).[42]
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."
Nasally administered oxytocin has been reported to reduce fear, possibly by inhibiting the amygdala (which is thought to be responsible for fear responses).[76] Indeed, studies in rodents have shown oxytocin can efficiently inhibit fear responses by activating an inhibitory circuit within the amygdala.[77][78] Some researchers have argued oxytocin has a general enhancing effect on all social emotions, since intranasal administration of oxytocin also increases envy and Schadenfreude.[79] Individuals who receive an intranasal dose of oxytocin identify facial expressions of disgust more quickly than individuals who do not receive oxytocin.[75][qualify evidence] Facial expressions of disgust are evolutionarily linked to the idea of contagion. Thus, oxytocin increases the salience of cues that imply contamination, which leads to a faster response because these cues are especially relevant for survival. In another study, after administration of oxytocin, individuals displayed an enhanced ability to recognize expressions of fear compared to the individuals who received the placebo.[80] Oxytocin modulates fear responses by enhancing the maintenance of social memories. Rats that are genetically modified to have a surplus of oxytocin receptors display a greater fear response to a previously conditioned stressor. Oxytocin enhances the aversive social memory, leading the rat to display a greater fear response when the aversive stimulus is encountered again.[74]
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.

Showa Denko, the source of up to 60% of all the tryptophan sold in the United States, had used an untested manufacturing process that reduced the amount of activated charcoal used to filter fermented raw tryptophan. Some reports suggest that purity may be a potential problem for 5-HTP as well. No cases of EMS resulting from 5-HTP use have been reported, however.

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.

Double immunofluorescent staining for BrdU (red, A) and NeuN (green, B) to identify newborn neurons (yellow after merge, C) in the dentate gyrus of hippocampus from rats examined 35 days after TBI. Micrographs (D) show location of DiI injection in the CA3 region (indicated by white asterisk). In the CA3 region, axons projected from granule neurons in the dentate gyrus will take up injected DiI to their cell bodies. Co-localization (merge, H) of BrdU-positive nuclei (green, F) within retrogradely DiI labeled (red, E) granule cells were examined at 35 days after TBI. Scale bar = 25 μm (C, H). Scale bar = 50 μm (D).

TB-500 is a synthetic version of the naturally occurring peptide present in virtually all human and animal cells, Thymosin Beta-4. This potent peptide is a member of a ubiquitous family of 16 related molecules with a high conservation of sequence and localization in most tissues and circulating cells in the body. TB-500 not only binds to actin, but also blocks actin polymerization and is the actin-sequestering molecule in eukaryotic cells.

5-HTP is converted by the body to serotonin, a chemical in the brain that plays an important role in mood, sleep, and appetite. Many prescription medications used for the treatment of depression increase serotonin concentrations in the brain. Because of 5-HTP's pathway to serotonin, it has appealed to researchers as well as the public as a "natural" alternative to antidepressants and treatment of depression, insomnia, migraines, obesity, and fibromyalgia.
Work with cell cultures and experiments with animals have shown that administration of thymosin β4 can promote migration of cells, formation of blood vessels, maturation of stem cells, survival of various cell types and lowering of the production of pro-inflammatory cytokines. These multiple properties have provided the impetus for a worldwide series of on-going clinical trials of potential effectiveness of thymosin β4 in promoting repair of wounds in skin, cornea and heart.[17]
