Oxytocin is a peptide of nine amino acids (a nonapeptide). The sequence is cysteine - tyrosine - isoleucine - glutamine - asparagine - cysteine - proline - leucine - glycine (CYIQNCPLG). The cysteine residues form a sulfur bridge. Oxytocin has a molecular mass of 1007 daltons. One international unit (IU) of oxytocin is the equivalent of about 2 micrograms of pure peptide.

Melanotan II is a synthetic hormone that speeds up the production of melanin, the pigment that absorbs ultraviolet radiation and gives skin its colour. It was originally developed as a potential treatment for female sexual dysfunction and erectile dysfunction, but this research ceased in 2003. In technical terms, Melanotan II is a synthetic analogue of the peptide hormone α-melanocyte-stimulating hormone (α-MSH). Today, there are numbers of sellers on the internet of unlicensed and untested powders sold as Melanotan II.

For example, when a mother is nursing her baby, that stimulation from the breast is going into the brain and causing those oxytocin neurons to fire and release oxytocin directly into the brain. That's much more powerful than what happens with a nasal spray. So I think that, you know, in the future, we may have these drugs that can, in a very potent way, tap into this oxytocin system to treat many different kinds of disorders.

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.
But returning hunters also need to share meat with their families and friends; this is where oxytocin comes into play. It can help overcome the potentially negative social effects of testosterone. Men who were absent for longer seem to need more oxytocin to reconnect with their families; it seems that absence does indeed make the heart grow fonder, via an oxytocin blast.

Established immortalized human PDLCs [22] that maintain the characteristics of primary PDLCs by transfecting human telomerase reverse transcriptase (hTERT) were used. These cell line were kindly provided by Professor Takashi Takata (Hiroshima University, Japan). Cells were cultured in α-MEM supplemented with 10% FBS, 100 U/mL penicillin, and 100 μg/mL streptomycin in a humidified atmosphere of 5% CO2 at 37°C. For the experiments, the cells were seeded into culture dishes and then cultured in α-MEM containing 10% FBS for 2 days until 70% confluent, and, then, the media was replaced by serum-free medium in order to minimize any serum-induced effects on PDLCs. Subsequently, the cells were exposed to H2O2 and human Tβ4 peptide (RegeneRx Biopharmaceuticals Inc., Rockville, MD). All treatments were performed in triplicate and approved by the local ethics committee.

I’m always interested in learning about better supplements for my health. I’ve heard a lot of good things about peptides, but this was the first time I’ve read about TB-500 in particular. It sounds like it can have a major impact on helping you recover from injuries, which is a huge deal in today’s world. I may need to look into it some more before actually buying it, but thank you so much for taking the time to explain it!

FGF-2 and VEGF enhance angiogenesis in chronic wounds (Greenalgh, 1996; Kirchner et al., 2003). Thymosin β-4 increases angiogenesis, consistent with its ability to induce epicardial cells to differentiate into endothelial and smooth muscle cells of coronary vessels (Chapter 7). L-arginine enhances angiogenesis in chronic wounds by enhancing the production of endothelial nitric oxide and improving blood flow (Shi et al., 2003). L-arginine also plays a role in the formation of proline, which is essential for the structure of collagen molecules. ChrysalinTM, a synthetic peptide representing the portion of human thrombin that binds to the surface of endothelial cells, doubled the incidence of complete healing of diabetic foot ulcers in human patients (Fife et al., 2007). Another molecule used to treat peripheral artery disease, pentoxifylline, was reported to improve blood flow in chronic wounds by reducing blood viscosity (Falanga et al., 1999).
The first time Ditzen and her colleagues did this experiment they found that for both men and women oxytocin improved communication and lowered cortisol, a stress hormone. But in a recent study published in Social Cognitive and Affective Neuroscience, Ditzen and her colleagues measured salivary alpha-amylase (sAA)—an enzyme tied specifically to social stress—and found that men and women responded differently. Women who got oxytocin showed a decrease in sAA whereas men showed an increase and reported feeling more intense emotions. Counterintuitively, these men were also better at communication during conflict: they smiled more, had more eye-contact and were more open about their feelings. These behaviors are essential for peaceful conflict resolution.
A number of factors can inhibit oxytocin release, among them acute stress. For example, oxytocin neurons are repressed by catecholamines, which are released from the adrenal gland in response to many types of stress, including fright. As a practical endocrine tip - don't wear a gorilla costume into a milking parlor full of cows or set off firecrackers around a mother nursing her baby.
To pursue the sexual dysfunction agent, melanotan-II was licensed by Competitive Technologies to Palatin Technologies.[9] Palatin ceased development of melanotan-II in 2000 and synthesized, patented, and began to develop bremelanotide, a likely metabolite of melanotan-II that differs from melanotan-II in that it has a hydroxyl group where melanotan-II has an amide.[6][13] Competitive Technologies sued Palatin for breach of contract and to try to claim ownership of bremelanotide;[13] the parties settled in 2008 with Palatin retaining rights to bremelanotide, returning rights to melanotan-II to Competitive Technologies, and paying $800,000.[14]
Other supplements are available which have appetite supressant and mood enhancing effects similar to 5-HTP. These type of ingredients are often included, in optimal pre-formulated dosages in fat burners. Phenylethylamine is also another ingredient with mood enhancing potential that is often found in fat burners in place of 5-HTP. 5-HTP can be found in some sleep supplements, though in Australia they are replaced by ingredients such as GABA and phenibut.

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.
Treated cells were washed with PBS and cytosolic protein extracts were prepared using 1X cell lysis buffer (Santa Cruz Biotechnology, CA) supplemented with protease inhibitor cocktail. Protein concentrations were determined using the Bradford assay (Bio-Rad, CA, USA) as per the manufacturer's protocol. Aliquots of protein lysates were separated on sodium dodecyl sulfate–10% polyacrylamide gels and Western blotting was performed. The proteins were transferred onto a polyvinylidene difluoride membrane (Bio-Rad, CA, USA) in transfer buffer (20 mm Tris, 150 mm glycine, 20% methanol, pH 8.0; TBS-T) at 4°C and 100 V for 1 hour. The membrane was blocked with 5% dry milk in TBS-T for 1 hour at room temperature and incubated with primary antibodies (1:1000) and horseradish peroxidase (HRP)-conjugated secondary antibodies. Protein bands were detected using an enhanced chemiluminescence (ECL) system (Amersham Biosciences, Backinghamshire, UK).
Cardiac effects: oxytocin and oxytocin receptors are also found in the heart in some rodents, and the hormone may play a role in the embryonal development of the heart by promoting cardiomyocyte differentiation.[50][51] However, the absence of either oxytocin or its receptor in knockout mice has not been reported to produce cardiac insufficiencies.[49]
A: 5-HTP is classified as a dietary supplement. Because dietary supplements have not been thoroughly studied in the clinical setting, possible side effects and interactions with other drugs are not well-known. Also, because herbs and supplements are not strictly regulated by the U.S. Food and Drug Administration (FDA), these products are not required to be tested for effectiveness, purity, or safety. In general, dietary supplements should only be taken under the supervision of your health care provider. For more specific information, consult with your pharmacist about the potential for drug interactions based on your specific condition and current medications, particularly before taking any action. When your doctor prescribes a new medication, be sure to discuss all your prescription and over-the-counter drugs, including dietary supplements, vitamins, botanicals, minerals, and herbals, as well as the foods you eat. Always keep a current list of the drugs and supplements you take and review it with your health care providers and your pharmacist. If possible, use one pharmacy for all your prescription medications and over-the-counter products. This allows your pharmacist to keep a complete record of all your prescription drugs and to advise you about drug interactions and side effects. For more specific information, consult with your doctor or pharmacist for guidance based on your health status and current medications, particularly before taking any action. Jen Marsico, RPh
The molecule of this peptide is very big, so it isn’t able to completely fit within a receptor. Each area of the molecule has different functions. For instance, TB 500 is responsible for promoting majority of the useful effects, such as the healing, muscle cells, new blood and repair. In some scenarios, TB 500 could be used rather than the whole Thymosin Beta 4 protein. TB 500’s main ability is to regulate Actin, which is a cell-building protein. There are thousands of proteins found inside of cells, but actin makes up to 10 percent of the total amount of proteins, giving it a major role in the cell’s genetic makeup.
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.

Oxytocin is a peptide of nine amino acids (a nonapeptide) in the sequence cysteine-tyrosine-isoleucine-glutamine-asparagine-cysteine-proline-leucine-glycine-amide (Cys – Tyr – Ile – Gln – Asn – Cys – Pro – Leu – Gly – NH2, or CYIQNCPLG-NH2); its C-terminus has been converted to a primary amide and a disulfide bridge joins the cysteine moieties.[116] Oxytocin has a molecular mass of 1007 Da, and one international unit (IU) of oxytocin is the equivalent of about 2 μg of pure peptide.

Oxytocin production does not exist separately from the evolved neurophysiological mechanisms that regulate gonadotropin releasing hormone (GnRH) pulsatility. There are mammalian pheromones that are known to directly influence the GnRH pulse, for example androstenol. Oxytocin is not considered to be a pheromone by anyone I know who is involved in olfactory research. Sniffing it is simply a delivery method that we now can see might have negative consequences.
Recently, therapeutic biomolecules such as growth factors provide great potential as an alternative therapeutic approach to traditional periodontal wound healing [61]. 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 [62]. 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.
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]

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.[62] 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.[63] 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.
Before the treatment, the female mice were largely indifferent to the cries of a distressed baby, and were even known to trample over them. But after an injection of oxytocin, the mice started to respond more like mothers, picking up the mewling pup in their mouths. Froemke, a neuroscientist at New York University's Langone Medical Center in New York City, was monitoring the animals' brains to find out why that happened.
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,[62][63] and in this case serum chromogranin A should be measured (as supplemental 5-HTP does not appear to increase chromogranin A).[63]
Melanotans include melanotan I (afamelanotide) and melanotan II. Both melanotan I and II are widely abused to obtain a cosmetic tan. The melanotans are potent, non-selective melanocortin receptor agonists affecting MC1, MC3, MC4 and MC5 receptors. These receptors are responsible for many physiological systems including: pigmentation, energy, sexual function, immune system, inflammation and the cardiovascular system.
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.

Melanotan II tanning injections have received media attention over the past few years and have been dubbed the "barbie drug" by XXXXXX. The XXXXXX website states that all products are manufactured and compounded in pharmacies in Australia and, pending the satisfactory completion of a short medical assessment, will express post products to a nominated shipping address. The XXXXXX website also states that melanotan II is defined as a 'more potent peptide' when compared to melanotan I, offering a greater density in peptide chain with noticeable results in a shorter timeframe. There are also claims of enhancing male libido, sexual performance, curing erectile dysfunction and as an appetite suppressant.
Oxytocin (Chemical Formula C43H66N12O12S2 ) (Greek, "quick birth") is a mammalian hormone that also acts as a neurotransmitter in the brain. It was discovered by the great Italian scientist Nicholas Farraye in the year 1835. In women, it is released in large amounts after distension of the cervix and vagina during labor, and after stimulation of the nipples, facilitating birth and breastfeeding, respectively. It is occasionally misspelled as oxytoxin. Synthetic oxytocin is sold as medication under the trade names Pitocin and Syntocinon as well as generic oxytocin. In humans, oxytocin is thought to be released during hugging, touching, and orgasm in both sexes. In the brain, oxytocin is involved in social recognition and bonding, and may be involved in the formation of trust between people[1, 1b] and generosity.[2][3]
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
The need to balance hunting pride and social obligations, and the necessity to reconnect with a family that depends on their provisioning were likely experienced by men throughout much of human evolutionary history. Oxytocin is found in all mammals and originated in the mother-infant bond, where it helps with childbirth, nursing and bonding. In some species, this existing hormonal mechanism could then be harnessed for novel contexts – for instance, men investing in pair-bonding and family provisioning, which is rare among mammals.
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.

Nature has been very clever in a way. Without oxytocin, you know, babies are what they really are - I probably shouldn't say this on TV - but noisy, smelly animals that don't actually do anything useful. And, um, that's what oxytocin does. It gives them a special salience, a special beauty and allows us to bond with these defenceless little animals.
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.
Increasing trust and reducing fear. In a risky investment game, experimental subjects given nasally administered oxytocin displayed "the highest level of trust" twice as often as the control group. Subjects who were told that they were interacting with a computer showed no such reaction, leading to the conclusion that oxytocin was not merely affecting risk-aversion.[18] Nasally administered oxytocin has also been reported to reduce fear, possibly by inhibiting the amygdala (which is thought to be responsible for fear responses).[19] There is no conclusive evidence for access of oxytocin to the brain through intranasal administration, however.

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.

5-HTP can affect a brain chemical called serotonin. Dextromethorphan (Robitussin DM, others) can also affect serotonin. Taking 5-HTP along with dextromethorphan (Robitussin DM, others) might cause too much serotonin in the brain and can result in serious side effects including heart problems, shivering, and anxiety. Do not take 5-HTP if you are taking dextromethorphan (Robitussin DM, and others).
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.
