Oxytocin is a powerful hormone that acts as a neurotransmitter in the brain. It regulates social interaction and sexual reproduction, playing a role in behaviors from maternal-infant bonding and milk release to empathy, generosity, and orgasm. When we hug or kiss a loved one, oxytocin levels increase; hence, oxytocin is often called "the love hormone." In fact, the hormone plays a huge role in all pair bonding. The hormone is greatly stimulated during sex, birth, and breastfeeding. Oxytocin is the hormone that underlies trust. It is also an antidote to depressive feelings.
When we asked a group of readers to test out 5-HTP to lose weight, they ate unlimited portions of healthy food and still shed up to five pounds in a week. We also talked to women who’d been using 5-HTP long term. Heather Miars started taking 5-HTP for her mood at Dr. Bhatia’s urging. “I was finally able to go off prescription antidepressants and lose 15 pounds!” recalls the 45-year-old mom. Meanwhile, Audra Holmes tried 5-HTP after developing “mood swings so wild, I was giving people whiplash,” she jokes. On 5-HTP, she says: “I didn’t have the highs and lows. I could suddenly get through the day without naps or comfort food!” She shed 50 pounds in 16 weeks. Wish you could have the same kind of success with an easy way to lose weight? As Dr. Oz put it: “5-HTP may be your pre-meal must-have!”

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.
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.[30][31] 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[32] as assessed by a Flashmark Pro recording device.[33]

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]
In December 2010, the delegate made a delegate only decision to include afamelanotide (also known as melanotan I) with a cross-reference to melanocyte stimulating hormone (MSH) for inclusion into the current Poisons Standard. It was noted that afamelanotide should not be confused with a similar substance commonly known as Melanotan-II, which is a cyclic lactam synthetic analogue of α-MSH. It was noted that melanotan-II was under investigation for treating sexual dysfunction, although this has been abandoned due to side effects associated with the immune and cardiovascular systems. Its metabolite, bremelanotide, is under investigation for treating haemorrhagic shock.
Maternal behavior: Female rats given oxytocin antagonists after giving birth do not exhibit typical maternal behavior.[59] By contrast, virgin female sheep show maternal behavior toward foreign lambs upon cerebrospinal fluid infusion of oxytocin, which they would not do otherwise.[60] Oxytocin is involved in the initiation of maternal behavior, not its maintenance; for example, it is higher in mothers after they interact with unfamiliar children rather than their own.[61]
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 biologically active form of oxytocin, commonly measured by RIA and/or HPLC techniques, is also known as the octapeptide "oxytocin disulfide" (oxidized form), but oxytocin also exists as a reduced straight-chain (non-cyclic) dithiol nonapeptide called oxytoceine.[120] It has been theorized that oxytoceine may act as a free radical scavenger, as donating an electron to a free radical allows oxytoceine to be re-oxidized to oxytocin via the dehydroascorbate / ascorbate redox couple.[121]

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.
These proteins became of interest in neurobiology with the finding that in the nudibranch (sea slug) Hermissenda crassicornis, the protein Csp24 (conditioned stimulus pathway phosphoprotein-24), with 4 repeats, is involved in simple forms of learning: both one-trial enhancement of the excitability of sensory neurons in the conditioned stimulus pathway,[25] and in multi-trial Pavlovian conditioning.[26] The phosphorylation of Csp24, in common with post-translational modifications of a number of cytoskeleton-related proteins may contribute to actin-filament dynamics underlying structural remodeling of responsive cells.[26]

The mRNA and protein expressions were determined by PCR analysis (A) and Western blot analysis (B), respectively. The bar graph shows the fold increase in protein or mRNA expression compared with control cells * Statistically significant differences compared with the control, p<0.05. The data presented were representative of three independent experiments.
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.
In the experiments, an epithelial wound was made in the corneas of sedated rats. A Tb4 solution was applied at several concentrations to the injured eyes in one group of rats while another group was treated with a solution without Tb4. Following 12, 24 and 36 hours, the eyes were tested by microscopic observation for epithelial growth over the injured site. Investigators found the Tb4 accelerated corneal wound repair at doses of Tb4 similar to those found to repair skin wounds. When tested 24 hours after treatment, the rate of accelerated repair was proportional to the concentration of Tb4, with the highest dose (25 microgram) showing a threefold acceleration of epithelial cell migration, compared to untreated. Treatment with Tb4 showed anti-inflammatory effects, helping resolve the injury. An application to human cells in a model of human corneal cells in culture showed that Tb4 enhanced epithelial cell migration in vitro.
Thymosin Beta 4 is a peptide that was first found within the thymus gland. Since its discovery, other types of thymosin have been found in different tissues throughout test subjects. Thymosin Beta 4 is typically found in both types of muscles – skeletal (the muscles that are required to move) and smooth muscles (such as the heart). When damage occurs in a tissue, Thymosin Beta 4 is upregulated. Then when traumas take place, Thymosin Beta 4 is released in order to help the subject heal from the trauma. This peptide also helps to prevent adhesions from forming, which means there will be less scar tissue and potentially more flexibility. It has potent anti-inflammatory characteristics.

How not surprising on one level that a hormone involved in the formation of primary bonds, those that can have serious impacts on your survival, would be discerning. After all, if you had a mother who was dangerous, abusive, etc., how counter productive would it be for you to bond so tightly to her that you were all over her all the time, increasing your chances of pissing her off and killing you. And, how beneficial for you to be more bonded to a mother figure who was good to you, and provided you with nurture.

The expression of Tβ4 mRNA is cell cycle dependent and is highest at the G0/G1 transition and during S-phase (), and changes in the expression of Tβ4 appear to be related to cell differentiation. It has been reported that hepatocyte growth factor, nerve growth factor or fibroblast growth factor (FGF) can increase the level of Tβ4 mRNA () and, in addition, interferon treatment augments the transcription of the Tβ4 gene (). It has also been shown that increased Tβ4 expression in cancer cells promotes metastasis, possibly by increasing cell mobility.
5-HTP is very reliable in increasing serotonin levels. 5-HTP is actually used as a clinical test to judge the potency of drugs that affect serotonin levels (by pairing an experimental drug with 5-HTP to induce 'serotonin syndrome', or serotonin toxicity, one can see how much that drug exacerbates serotonin biosynthesis or bioavailability by seeing how much of a 5-HTP dose is required to induce the syndrome; the lower dose indicative of higher drug potency). This test is known as the 5-HTP induced syndrome test.[8]

On the most basic level, a peptide is essentially a small protein. Billions of unique peptides exist, all with different effects and functions in the body. Physiological examples include insulin, oxytocin, and casein, the main protein in milk. Thus, to taunt Essendon supporters for the use of “peptides” is rather non-specific. A much more intelligent insult would be to focus on the administration of thymosin beta-4.
Cells that line blood vessels (endothelial cells), taken from human umbilical chord veins, were grown in culture and the layer of cells subjected to a scratch wound. Cultures were then treated with Tb4 or kept in growth medium without Tb4. When examined four hours later, Tb4 treatment attracted cells to migrate into the wound and accelerated their movement, showing it is a chemoattractant. Cell migration was four to six times faster in the presence of Tb4 compared to the migration of untreated cells. Tb4 also hastened wound closure and increased the production of enzymes, called metalloproteases, that could pave the way for angiogenesis by breaking down barrier membranes and facilitating the invasion of new cells to the needy area, to form new vessels. Other experiments showed Tb4 acts in vivo. When endothelial cells were implanted under the skin in a gel supplemented with Tb4, the cells formed vessel-like structures containing red blood cells, indicating the ability to stimulate angiogenesis in the animals.
At least one study using an extract of Griffonia simplicifolia (10.24mg giving 2.56mg 5-HTP; confounded with Centella asiatica and Taraxacum officinale at 11.7mg and 4.55mg Paulina cupana and 9.75mg Artichoke extract) taken in three hits, five times a day (40mg 5-HTP total), by 20 overweight or obese females (non-depressive and without eating disorders) for 4 weeks has noted an increase in satiety and reduced binge eating tendencies; the increase in satiety was said to account for the improved weight loss results seen in the experimental group when both were given weight loss advice and diets.[3] This spray has been noted elsewhere to increase satiety (and vicariously through that, body weight) over 2 months in a similar demographic of women.[2]
Traumatic brain injury (TBI) remains a leading cause of mortality and morbidity worldwide. No effective pharmacological treatments are available for TBI because all Phase II/III TBI clinical trials have failed. This highlights a compelling need to develop effective treatments for TBI. Endogenous neurorestoration occurs in the brain after TBI, including angiogenesis, neurogenesis, synaptogenesis, oligodendrogenesis and axonal remodeling, which may be associated with spontaneous functional recovery after TBI. However, the endogenous neurorestoration following TBI is limited. Treatments amplifying these neurorestorative processes may promote functional recovery after TBI. Thymosin beta4 (Tβ4) is the major G-actin-sequestering molecule in eukaryotic cells. In addition, Tβ4 has other properties including anti-apoptosis and anti-inflammation, promotion of angiogenesis, wound healing, stem/progenitor cell differentiation, and cell migration and survival, which provide the scientific foundation for the corneal, dermal, and cardiac wound repair multicenter clinical trials. Here, we describe Tβ4 as a neuroprotective and neurorestorative candidate for treatment of TBI.
A and B; Mouse BMMs were cultured with 200 μM H2O2 and indicated concentrations of Tβ4 peptide in the presence of M-CSF (30 ng/mL) and RANKL (100 ng/mL). C and D; PDLCs were co-cultured with mouse BMMs in the presence of M-CSF, RANKL, 200 μM H2O2, and indicated concentrations of Tβ4 peptide. To monitor osteoclast differentiation, both TRAP activity and the number of TRAP multinucleated cells were examined. * Statistically significant difference compared with control, p<0.05. The data presented were representative of three independent experiments.
Hi..i had 3 major muscle tears(complete)..2 in shoulder and 1in bicep..they all needed surgery for reattachment.. ive done a 20 day round with 157 and believed it helped..im at 7 weeks post op and have about 5 month’s of recovery still to go.. thinking another round of 157..wondering if the TB500 might be a better option or stay with 157? As an athlete and top Spartan racer,im looking to speed up process by any %. Any thoughts/opinions or recommendations are greatly appreciated! Thanks for your help and this info :)

Before all of this, the men completed a series of widely used questionnaires to measure the state of their social ties. The questions assessed the nature of their bonds with their families and friends, how sensitive they are to rejection, how comfortable they are at being close to other people, how much they desire that closeness, and more. Shortly after using both sprays, the recruits also answered questions about their mother’s parenting style.
Side effects:  Side effects for Melanotan 2 include nausea, appetite loss, facial flushing and increased libido. Side effects are generally mild and tend to diminish over time. Some research suggests nausea can be reduced by injecting MT-II after dinner or before bed. Athletes and bodybuilders have injected peptides like Melanotan 2 intermittently to prolong their tan since a tan aided by Melanotan can last 2-3 times as long as a normal tan. Like other peptides, Melanotan is a fragile molecule, therefore Melanotan nasal sprays, pre-mixed peptides, pills, oral and loose powder are not often legitimate for research effectiveness.
