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.
Touting their discovery as “a great step forward in weight loss history,” the panel were quick to offer up their hard earned cash to back the entrepreneurial pair. “We were shocked. The most we were hoping for was some advice…we weren’t even sure that we would manage to get any investors,” explained Samantha. After outstanding offers from each panel member, the sisters burst into tears.
In the prairie vole, oxytocin released into the brain of the female during sexual activity is important for forming a pair bond with her sexual partner. Vasopressin appears to have a similar effect in males. Oxytocin has a role in social behaviors in many species, so it likely also does in humans. In a 2003 study, both humans and dog oxytocin levels in the blood rose after five to 24 minutes of a petting session. This possibly plays a role in the emotional bonding between humans and dogs.
Thymosin beta-4 is a very large molecule. In fact, it is so large that it cannot fit entirely into the receptor. Different sections of the molecule have different activities. TB-500 is the part of thymosin beta-4 hormone which promotes the most useful effects (overall healing, repair, new blood and muscle cells). For medical applications it is more practical to use the TB-500 instead of the entire Thymosin Beta-4 protein.
But this isn’t the only study to show the subtle side of oxytocin. Just three months ago, I wrote about research from Heejung Kim at the University of California, which showed how oxytocin’s effects vary across different cultures. To fulfil its many roles, oxytocin has to dock at a protein called the ‘oxytocin receptor’, encoded by a gene called OXTR.
While all of the effects described above certainly occur in response to oxytocin, doubt has recently been cast on its necessity in parturition and maternal behavior. Mice that are unable to secrete oxytocin due to targeted disruptions of the oxytocin gene will mate, deliver their pups without apparent difficulty and display normal maternal behavior. However, they do show deficits in milk ejection and have subtle derangements in social behavior. It may be best to view oxytocin as a major facilitator of parturition and maternal behavior rather than a necessary component of these processes.
Suggested doses vary depending on the source – some sellers will encourage higher use! One site suggests starting with a dose of 0.25mg. If side-effects (see above) are not proving troublesome, the site advises users to attempt to increase daily dosage. After 2-3 weeks of daily use, or when the desired level of pigmentation has been achieved, people who use Melanotan II should start a maintenance phase of two injections per week.
In reality, SSRIs and 5-HTP aren't so different. Both affect serotonin. SSRIs work by blocking serotonin from being reabsorbed by nerve cells so more serotonin is available to help brain cells work efficiently. As a doctor would later tell me, 5-HTP, on the other hand, "provides your body with the tools to make more serotonin, as opposed to antidepressants, which are just working with the serotonin that you have already."
In another study, published in PNAS in 2010, men were given a dose of oxytocin and asked to write about their mothers. Those with secure relationships described their moms as more caring after the hormone dose. Those with troubled relationships actually saw their mothers as less caring. The hormone may help with the formation of social memories, according to the study researchers, so a whiff strengthens previous associations, whether good or bad.
The diverse activities related to tissue repair may depend on interactions with receptors quite distinct from actin and possessing extracellular ligand-binding domains. Such multi-tasking by, or "partner promiscuity" of, proteins has been referred to as protein moonlighting. Proteins such as thymosins which lack stable folded structure in aqueous solution, are known as intrinsically unstructured proteins (IUPs). Because IUPs acquire specific folded structures only on binding to their partner proteins, they offer special possibilities for interaction with multiple partners. A candidate extracellular receptor of high affinity for thymosin β4 is the β subunit of cell surface-located ATP synthase, which would allow extracellular thymosin to signal via a purinergic receptor.
These results were in agreement with previous studies that showed Wnt5a expression can be induced in activated macrophages, endothelial cells, and bone marrow mesenchymal stem cells (BMSCs) after inflammatory stimulation [58, 59]. In addition, we found that the effects of Tβ4 peptide on H2O2-mediated induction of pro-inflammatory cytokines (NO, PGE2, TNF-α, IL-1β, IL-6, IL-8, and IL-17), the expression of inflammatory mediators (iNOS and COX-2), osteoclastogenic cytokines (cathepsin-K, calcitonin receptor or Calcr, NFATc1, and RANK), and osteoclastic differentiation, were reversed by exogenous treatment with Wnt5a siRNA but enhanced by rh-Wnt5a, suggesting that the anti-inflammatory and anti-osteoclastogenetic effects of Tβ4 activation were involved the Wnt5a-dependent signaling pathway. Similar to our results, Wnt5a knock-down markedly reduced cytokine/chemokine production induced by TNF in HDPCs .
5-HTP supplements are made using an extract from the seeds of Griffonia simplicifolia,a tree native to Africa (2). 5-HTP very rarely occurs naturally in what we eat, but tryptophan, from which 5-HTP is made in the body, is found in a variety of foods. The richest natural food sources include cheese, poultry, eggs, fish, nuts, soy, and various greens.
Synthetic oxytocin is sold as medication under the trade names Pitocin and Syntocinon and also as generic oxytocin. Oxytocin is destroyed in the gastrointestinal tract, and therefore must be administered by injection or as nasal spray. Oxytocin has a half-life of typically about three minutes in the blood. Oxytocin given intravenously does not enter the brain in significant quantities - it is excluded from the brain by the blood-brain barrier. There is no evidence for significant CNS entry of oxytocin by nasal spray. Oxytocin nasal sprays have been used to stimulate breastfeeding but the efficacy of this approach is doubtful.
Hi Jesse, while I cant make specific sarms recommendations as it would be teetering on giving medical advice, I have a ton of resources on this on BenGreenfieldFitness.com that you can easily search through. There is also a lot of invaluable discussion on sarms going on in the comments sections of these articles. The Kion Community is also a great place to ask a question like this: https://Facebook.com/groups/GetKion
5-HTP has been investigated for its role in hot flashes as Selective Serotonin Reuptake Inhibitors (SSRIs) have been noted to reduce the occurrence of hot flashes and menopausal symptoms. In a study in menopausal females given 150mg 5-HTP daily (50mg taken thrice a day) for a period of one week failed to quantitivatively reduce the occurrance of hot flashes as assessed by a Flashmark Pro recording device.
So far, few studies have definitively linked autism to problems in oxytocin signalling. Some of the clearest evidence emerged in February, from a team led by neurogeneticist Daniel Geschwind of the University of California, Los Angeles. The group showed that mice that lacked a working copy of the Cntnap2 gene — which has been implicated in a small subset of human autism cases — had fewer oxytocin-containing neurons in the hypothalamus and socialized less with other mice than did control mice15. After receiving doses of oxytocin every day for two weeks, the mice behaved normally again. “Until this, there was no evidence that there was a subtype of autism that had to do with oxytocin deficits,” Geschwind says.
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.
In a 2-week long clinical trial involving 25 overweight diabetic subjects given no dietary restrictions, subjects who received 5-HTP had reduced caloric, carbohydrate, and fat intake compared to placebo. Subjects who received 5-HTP also have reduced body weight, blood sugar, insulin and HbA1C levels after 2 weeks, possibly due to changes in the diet (R).
Although maternal bonding may not always be hardwired — after all, human females can adopt babies and take care of them — oxytocin released during pregnancy "does seem to have a role in motivation and feelings of connectedness to a baby," Young said. Studies also show that interacting with a baby causes the infant's own oxytocin levels to increase, he added.
Unlike previous studies, the trial will include people with a wide range of symptoms — and one of its major aims is to uncover the set of factors that influence whether and how strongly people respond to oxytocin. Sikich will analyse many measures of cognition and social functioning, and collect blood samples to look for biomarkers — such as levels of oxytocin and the receptor it binds to — that are associated with a response. “Lin has really been trying to create conditions under which you could study the potential beneficial effects of oxytocin and really do this right,” says Carter.
In a study that hasn’t been published yet, Feldman found that oxytocin receptor genes are also linked to empathy in couples. She looked at variants in the gene that have been linked with an increased risk for autism, a disorder that is marked by major social communication deficits. She found that the more of these “risk variants” a person had, the less empathy they showed toward their partner when that partner shared a distressing experience.
What we noticed was that all the rats that had received oxytocin straight into their brain immediately prior to being given alcohol, were up and moving about and seemed to be completely sober. Whereas all of the rats that had just been given the alcohol were, as we would predict from the dose that we were giving them, quite drunk. And so we thought, 'Wow, what's going on here?' It was almost as though the oxytocin was blocking the intoxicating effects of the alcohol.
This current literature is notable for its apparent irrelevancy to an AFL footballer. It begs the question; did Tβ4 make a difference to the Essendon players? The only honest answer is that we don’t know. Most of our understanding exists on a molecular and cellular level, without any significant appreciation of how Tβ4 influences applicable outcomes such as exercise performance, endurance, muscle strength, and time to recovery. Furthermore, as the majority of research has been performed on mice, rat and pig models, any results are not directly translatable to a human, let alone an elite athlete. This is a stark contrast to a supplement such as EPO, which has been investigated thoroughly.
Thymosin beta 4 accelerated skin wound healing in a rat model of a full thickness wound where the epithelial layer was destroyed. When Tb4 was applied topically to the wound or injected into the animal, epithelial layer restoration in the wound was increased 42% by day four and 61% by day seven, after treatment, compared to untreated. Furthermore, Tb4 stimulated collagen deposition in the wound and angiogenesis. Tb4 accelerated keratinocyte migration, resulting in the wound contracting by more than 11%, compared to untreated wounds, to close the skin gap in the wound. An analysis of skin sections (histological observations) showed that the Tb4 treated wounds healed faster than the untreated. Proof of accelerated cell migration was also seen in vitro, where Tb4 increased keratinocyte migration two to three fold, within four to five hours after treatment, compared to untreated keratinocytes.
If you want to obtain anything other than trivial amounts of milk from animals like dairy cattle, you have to stimulate oxytocin release because something like 80% of the milk is available only after ejection, and milk ejection requires oxytocin. Watch someone milk a cow, even with a machine, and what you'll see is that prior to milking, the teats and lower udder are washed gently - this tactile stimulation leads to oxytocin release and milk ejection.
This is a great product, I have been having digestive problems after 13 major surgeries and suffering from Crohn's Disease my whole life. Currently I can only tolerate a liquid diet. Was very depressed, found this and started taking it and it has made a HUGE difference to my life. Only have very mild depression symptoms now, and sleep better at night. Bought the powder to get the dose right, looks like 100mg suits my 50 kg frame. Only bad thing is the packaging. The 10 grams of powder is lost in the large packet, very hard to get it out and measure the same dose every night. I purchased miniature measuring spoons from ebay and they make life much easier. Sort out the correct spoon for your dosage with the scales then off you go. Can be tricky getting it in and out of the bag, often get powder everywhere, but usually just lick it off. A pill container would work much better for this power.
My wife has suffered from debilitating leg cramps for years, usually nocturnal. We have spent much money and time trying to find a cure, including every type of magnesium supplement we could find. Nothing has worked. We’ve also tried MSM and DMSO. Sometimes the cramps are in her calves, sometimes her thighs, sometimes her back and even her toes. Sometimes several muscles cramp at once. She has a high tolerance for pain, but these cramps leave her sobbing. I have purchased TB-500 and received it today. Does your research offer any hope that this could help eliminate her muscle spasms?
A handful of large-scale clinical trials are now getting under way to test oxytocin and oxytocin-based therapies for autism spectrum disorder, and to work out who could benefit. Linmarie Sikich, a child psychiatrist at the University of North Carolina is heading the largest of these trials. Sikich plans to recruit 300 people with autism spectrum disorder, ranging in age from 3 to 17, and give them 6 months of either oxytocin or a placebo, followed by 6 months in which everyone will receive oxytocin.
There is no long-term side effects ever reported, but there is post injection effects while using Melanotan 2, typically these effects appear during the first few days of dosing and will become increasingly less obvious as the body adjusts to the peptide. These effects include: hot flush in face, mild nausea, decreased appetite, and increased sex drive. In order to combat nausea, an anti-histamine product can be taken until the body gets used to it. But most common way to deal with this is to take the dose before bed.
Surgery: 5-HTP can affect a brain chemical called serotonin. Some drugs administered during surgery can also affect serotonin. Taking 5-HTP before surgery might cause too much serotonin in the brain and can result in serious side effects including heart problems, shivering, and anxiety. Tell patients to stop taking 5-HTP at least 2 weeks before surgery.
