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.
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.
It should be noted that supplemental 5-HTP can cause an increase in urinary 5-HIAA, which is the major metabolite of serotonin that is excreted in the urine. Increased urinary 5-HIAA is also sometimes a diagonistic marker for carcinoid tumors due to increased conversion of tryptophan to serotonin in these tumors, and in this case serum chromogranin A should be measured (as supplemental 5-HTP does not appear to increase chromogranin A).
Autism. A 1998 study found significantly lower levels of oxytocin in blood plasma of autistic children. A 2003 study found a decrease in autism spectrum repetitive behaviors when oxytocin was administered intravenously. A 2007 study reported that oxytocin helped autistic adults retain the ability to evaluate the emotional significance of speech intonation.
Cells were pretreated with indicated concentrations of Tβ4 peptide for 2 hours and then incubated with 200 μM H2O2 for 48 hours (A-C). Protein expressions were assessed by Western blot analysis (A). The production of NO (B) and PGE2 (C) were measured by Griess reaction and ELISA, respectively. Data replicated the quantifications of NO and PGE2 with the standard deviation of at least three experiments (n = 4). 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.
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.
To determine whether MAPK and NF-κB signaling pathways were involved in the anti-osteoclastogenic function of Tβ4, the effect of Tβ4 peptide on the phosphorylation levels of ERK, JNK, and p38 MAPK(s) as well as the nuclear translocation of NF-κB p65 in RANKL-stimulated BMMs were examined. As shown in Fig 8B, Tβ4 peptide inhibited the RANKL-induced phosphorylation of p38, ERK, and JNK and nuclear translocation of NF-κB p65.
The oxytocin peptide is synthesized as an inactive precursor protein from the OXT gene. This precursor protein also includes the oxytocin carrier protein neurophysin I. 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).
Cells on the surface of the skin are constantly being replaced by regeneration from below. The repair of a wound is a scaling up of this normal process, with additional complex interactions among cells, formation of new blood vessels, collagen, more extensive cell division and cell migration, as well as strict control of inflammatory cells and the cytokines they release to resolve the inflammation.
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.
Recently, therapeutic biomolecules such as growth factors provide great potential as an alternative therapeutic approach to traditional periodontal wound healing . However, because of the short half-lives of growth factors and polynucleotides in the body and the necessity to deliver to specific target sites, those medicinal substances do not always exhibit the anticipated therapeutic potency and outcomes . Thus, optimized delivery regimes and well-defined release kinetics appear to be logical prerequisites for safe and efficacious clinical application of biomolecules. For considering the application of Tβ4 in clinical trials, target cells of exogenous Tβ4 should be restricted to cells in the periodontal tissue.
When practicing deep breathing, focus on a calmer state of mind as you distract yourself from overwhelming thoughts and sensations. Sit in a quiet area and practice the following: Take a slow, deep breath through your nose, allowing both your stomach and chest to rise. Once your stomach is fully expanded, breathe out through your mouth, just as slowly as when you were breathing in.
5-HTP helps the body to produce more serotonin. Serotonin is a neurotransmitter that plays a key role in regulating mood and sleep-wake cycles. Healthy levels of serotonin contribute to a positive mood and outlook and also promote restful sleep. Serotonin also plays an important role in many other of the body’s functions, including digestion, appetite, and pain perception.
5-HTP increases a brain chemical called serotonin. Some medications for depression also increase serotonin. Taking 5-HTP along with these medications for depression might increase serotonin too much and cause serious side effects including heart problems, shivering, and anxiety. Do not take 5-HTP if you are taking medications for depression.
Some of these medications for depression include fluoxetine (Prozac), paroxetine (Paxil), sertraline (Zoloft), amitriptyline (Elavil), clomipramine (Anafranil), imipramine (Tofranil), and others.
This may be an odd question. But would this be good to inject or spray on those that have undergone hair transplants in the first month of surgery. Fue microscars. I see you mention it improves hair growth and blood flow. both which basically what rogaine claims to do. Surely this would benefit new transplanted hair follicles in taking and holding? Interested in your thoughts in the matter.
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.
5-HTP is an easy way to lose weight on just about any diet, so you can choose any plan that appeals to you — or even no plan at all! But if you’re looking for a quick approach proven to work, use guidelines created by the University of Rome researchers. They allotted folks 1,200 calories a day, about half from carbs and the rest a mix of lean protein and fat. That means at most sittings, you’ll want to start with 200 calories of carbs, including both starchy carbs and carbs from produce (such as a bowl of cereal with fruit, or pasta with veggies). Add about 120 calories of protein (such as some Greek yogurt, egg whites or a few ounces of lean meat). Finish with 80 calories of fat, such as 10 almonds or 2 tsp. olive oil. An easy formula for fast weight loss if we've ever heard one!
The potential of Tb4 to repair sun damaged and aging skin is yet to be established by extensive studies. Many of the biological events that occur in wounding are involved in skin impaired by sun and aging. Ultraviolet radiation damage or other injuries to skin that are associated with aging may be in the future repairable with Tb4, similar to the success with wound repair. It is a hopeful prediction that this small anti-inflammatory molecule, which plays a vital role in regeneration, remodeling and healing of damaged tissues, would help rejuvenate aging skin. The effects of Tb4 in accelerating wound repair are important following surgery; Tb4 would then have practical applications following cosmetic surgery, a procedure growing in popularity in our society, in dealing with aging skin.
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 (CRH) and dynorphin, for example, that act locally. The magnocellular neurons that make oxytocin are adjacent to magnocellular neurons that make vasopressin, and are similar in many respects.
Ingroup bonding: Oxytocin can increase positive attitudes, such as bonding, toward individuals with similar characteristics, who then become classified as "in-group" members, whereas individuals who are dissimilar become classified as "out-group" members. Race can be used as an example of in-group and out-group tendencies because society often categorizes individuals into groups based on race (Caucasian, African American, Latino, etc.). One study that examined race and empathy found that participants receiving nasally administered oxytocin had stronger reactions to pictures of in-group members making pained faces than to pictures of out-group members with the same expression. This shows that oxytocin may be implicated in our ability to empathize with individuals of different races and could potentially translate into willingness to help individuals in pain or stressful situations. Moreover, individuals of one race may be more inclined to help individuals of the same race than individuals of another race when they are experiencing pain. Oxytocin has also been implicated in lying when lying would prove beneficial to other in-group members. In a study where such a relationship was examined, it was found that when individuals were administered oxytocin, rates of dishonesty in the participants' responses increased for their in-group members when a beneficial outcome for their group was expected. Both of these examples show the tendency of individuals to act in ways that benefit those considered to be members of their social group, or in-group.
Combined treatments of 5-HTP and SSRI seem to have strong synergistic effects on serotonin levels in rats and humans so that some clinicians recommend the use of slow-released 5-HTP in combination with SSRIs (R, R2, R3). However, additional clinical trials are required to demonstrate the safety and effectiveness of this approach, and combinations of 5-HTP and medications should only be used under medical supervision.
Research substantiates Wiebe's anecdotal claims. Melanotan.org, a forum dedicated to the peptide that shut down in 2011, had thousands of regular posters, many of whom have since migrated to other discussion boards. In 2009, a BBC report tracking just six needle exchanges found that hundreds of individuals had visited these exchanges in order to receive syringes for Melanotan II use. A year later, the Norwegian Pharmacy Association disclosed that, in Norway alone, several thousand syringes had been distributed to individuals seeking to inject the peptide. Linn Connie Danielsen, a model and blogger, told the Norwegian newspaper Verdens Gangthat Melanotan II helps ease the stressful impact of extended winter sun deprivation. "A nice tan in the winter is good to see," she said.
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 conclusion, this study is the first study to demonstrate that down-regulation of Tβ4 was observed in an in vitro model of H2O2-stimulated PDLCs. Tβ4 activation had anti-inflammatory effects via MAPK and NF-κB pathways in PDLCs and anti-osteoclastogenic effects via MAPK, NF-κB, and Wnt5a pathways in BMMs. These findings supported the fact that Tβ4 peptide could possibly be used in the development of a therapeutic drug for periodontitis and osteolytic disease.
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.

Eventually I found Dr Kristaps Paddock, a naturopathic doctor and 5-HTP expert from Maryland in the US. He said one benefit 5-HTP has over SSRIs is that it kicks in quickly for those with anxiety and depression. "Serotonin has a short metabolic half-life, so it metabolises very, very fast. It goes into the body and out at a great speed, unlike SSRIs, which take a while to take effect so a sufferer wouldn't be feeling good during that time, and in fact may be feeling more suicidal. SSRIs also then have to be weaned off slowly, whereas you can stop taking 5-HTP instantly." Another bonus, of course, is that it's natural rather than synthetic. "If you're seriously considering the supplement, you have to weigh the positives and negatives against each other. The toxicity with 5-HTP is lower than that of SSRIs, since it's natural. Also because it's metabolised much quicker, it'd get out of your system more quickly if there were any problems. On the other hand, the research basis for 5-HTP is dramatically lower, so it's important to think of that."
TB-500 was identified as a gene that was up-regulated four-to-six fold during early blood vessel formation and found to promote the growth of new blood cells from the existing vessels. This peptide is present in wound fluid and when administered subcutaneously, it promotes wound healing, muscle building and speeds up recovery time of muscles fibres and their cells. An additional key factor of TB-500 is that it promotes cell migration through a specific interaction with actin in the cell cytoskeleton. It has been demonstrated that a central small amino acid long-actin binding domain has both blood cell reproduction and wound healing characteristics. These characteristics are uncovered by accelerating the migration of endothelial cells and keratinocytes. It also increases the production of extracellular matrix-degrading enzymes.
Once the baby is born, oxytocin promotes lactation by moving the milk into the breast. When the baby sucks at the mother's breast, oxytocin secretion causes the milk to release so the baby can feed. At the same time, oxytocin is released into the brain to stimulate further oxytocin production. Once the baby stops feeding, the production of the hormone stops until the next feeding.
Some differences in cardiac anatomy exist between mammals and teleosts. The zebrafish ventricle has a thin wall of compact muscle surrounding a much larger compartment of myofibers organized into elaborate trabeculae. It is intriguing that this structure is very similar to that of the embryonic mammalian ventricle prior to its septation and fusion of trabeculer myofibers into a thick, vascularized wall (Sedmera et al., 2000). That the mammalian heart has a more differentiated, contractile anatomy is apparent not only in gross cardiac structure, but also in cellular features. Teleost cardiomyocytes are 2–10 times smaller, mononucleated, have a greatly-reduced sarcoplasmic reticulum and lack the T-tubule system found in skeletal muscle and mammalian cardiac muscle (Farrell, 1992). One might speculate that the teleost heart is better designed for growth and regeneration, while the mammalian heart is better designed for sheer contractile force. Nevertheless, none of the mentioned differences between lower and higher vertebrate hearts preclude the idea that the mammalian heart could be stimulated to regenerate, especially if that regeneration is due to mobilization of a progenitor cell population.
Good quality Griffonia Simplicifonia, however the pouch is a very inconvenient packaging choice! Why not use the small 25-50gm pill bottle type? I used to be a quality controller in food additives and it would be so perfect to take doses from and fairly cheap and easy to source. I can understand if this is a new product for your line however but you should invest in this for 5htp alone perhaps. Thank you though will be ordering more down the track!
Milk ejection reflex/Letdown reflex: in lactating (breastfeeding) mothers, oxytocin acts at the mammary glands, causing milk to be 'let down' into subareolar sinuses, from where it can be excreted via the nipple. Suckling by the infant at the nipple is relayed by spinal nerves to the hypothalamus. The stimulation causes neurons that make oxytocin to fire action potentials in intermittent bursts; these bursts result in the secretion of pulses of oxytocin from the neurosecretory nerve terminals of the pituitary gland.
The neurotransmitter serotonin is synthesized from the amino acid tryptophan through 5-HTP. In which tryptophan gets converted into 5-HTP via the enzyme tryptophan hydroxylase and 5-HTP gets converted into serotonin via the enzyme L-amino acid decarboxylase. Serotonin is later degraded into 5-hydroxyindoleacetic acid (5-HIAA) by monoamine oxidase.
5-HTP is sometimes taken by people coming down from MDMA to relieve post-MDMA dysphoria. As 5-HTP is a necessary precursor for the brain to produce more serotonin, and MDMA use depletes a person's natural serotonin levels, it is believed that taking 5-HTP after consuming MDMA will speed up serotonin production. DanceSafe claims that the anecdotal evidence is widespread and that the theory is physiologically reasonable. Backing up this approach is research conducted by Wang, et al. in 2007, which observed that MDMA-induced depletions of 5-HT (serotonin) were restored in rats after administration 5-HTP, and suggested that this approach might be clinically useful in abstinent MDMA users.
