Low oxytocin levels have been linked to autism and autistic spectrum disorders (e.g. Asperger syndrome) – a key element of these disorders being poor social functioning. Some scientists believe oxytocin could be used to treat these disorders. In addition, low oxytocin has been linked to depressive symptoms and it has been proposed as a treatment for depressive disorders. However, there is not enough evidence at present to support its use for any of these conditions.
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).
Total RNA was extracted from cells using Trizol (Invitrogen, Carlsbad, CA, USA) according to the manufacturer’s instructions. Reverse-transcription (RT)-PCR was performed using oligo deoxythymidine primer (Roche Diagnostics, Mannheim, Germany) in 20 μl volumes at 42°C for 60 min. The RT-PCR reaction was done with 1 μg of total RNA, 1 μl of 20 μM oligo dT primer, and 18 μl of reaction mixture by AccuPower RT/PCR PreMix (Bioneer, Daejeon, Korea). Then, PCR was performed in a 20 μl total mixture volume for 25 cycles at 95°C for 1 min, 55°C for 1 min, and 72°C for 1 min. Primer sequences are detailed in Table 1. PCR products were subjected to electrophoresis on 1.5% agarose gels and visualized with ethidium bromide.
What is serotonin and what does it do? Serotonin is a chemical that transmits messages between nerve cells. Known as the happy chemical, serotonin plays a major role in the body by contributing to well-being, good mood, appetite, memory, and sleep. This article looks at what happens when a person is deficient in serotonin, and whether it can aid depression. Read now
Disclaimer: Thymosin Beta 4 is a peptide that should only be purchased for use in experimentation and research. It should not be purchased for human use or any other purpose than for research. It is advised that once purchased, the peptide is used within experimental circumstances that are under strict lab regulations. It is recommended that researchers use protective gear in order to prevent contact with the substance. However, if exposure is made with the peptide, it is very important to cleanse the area immediately to prevent harm.
Hi Ben. Have a groin problem which I have had for years and it just won’t go away it’s not a hernia or osteitis pubis I had an MRI and the specialist said they wouldn’t operate. I can still play sport but I’m just less agile and slower than normal and it takes a few days for the groin pain to go away after sport. Would tb500 help to heal it or would bpc157 or something else be better? Thanks :)
Autism. A 1998 study found significantly lower levels of oxytocin in blood plasma of autistic children.7 A 2003 study found a decrease in autism spectrum repetitive behaviors when oxytocin was administered intravenously.8 A 2007 study reported that oxytocin helped autistic adults retain the ability to evaluate the emotional significance of speech intonation.9
The tb-500 has a systematic effect regardless of where it is injected. Some believe that thymosin beta-4 should be injected as close to the injury as possible however there is no evidence to show this would be superior. It can be injected subcutaneously (stomach fat) or intramuscularly (shoulders, thighs, buttocks). Injections should be given in different sites (rotated) each time. Depending on the spot, you can either feel nothing or you can feel slight pain - you will learn your favorite spots in time.
I am not a doctor and this is not to be taken, interpreted or construed as medical advice. Please talk with a licensed medical professional about this. I would say yes though. Just because you dont “know” or “feel” any injury, you might be one functional movement away from a weakened tendon or muscle – snap, crackle and POP! These are just my own personal thoughts and not a prescription or a diagnosis or any form of health care whatsoever.
Thymosin beta(4), a small ubiquitous protein containing 43 aa, has structure/function activity via its actin-binding domain and numerous biological affects on cells. Since it is the major actin-sequestering molecule in eukaryotic cells and is found essentially in all cells and body fluids, thymosin beta(4) has the potential for significant roles in tissue development, maintenance, repair, and pathology. Several active sites with unique functions have been identified, including the amino-terminal site containing 4 aa (Ac-SDKP) that generally blocks inflammation and reduces fibrosis. Another active site at the amino terminus contains 15 aa, including Ac-SDKP, and promotes cell survival and blocks apoptosis, while a short sequence containing LKKTETQ, the central actin-binding domain (aa 17-23) plus 1 additional amino acid (Q), promotes angiogenesis, wound healing, and cell migration. Several additional biological activities have been identified but not yet localized in the molecule, including its antimicrobial activity, the induction of various genes (including laminin-5, MMPs, TGF beta, zyxin, terminal deoxynucleotidyl transferase, and angiogenesis-related proteins), and the ability to activate ILK/PINCH/Akt, and other signaling molecules important in both apoptosis and inflammatory pathways. This review details these important physiologically and pathologically active sites and their potential therapeutic uses.
5-HTP, along with other L-Tryptophan supplements, have been implicated in the flu-like, potentially fatal Eosinophilic Myalgia Syndrome. This syndrome was initially tied to  impurities - Amino Acids called "Peak E" and "Peak X" - which were present in these products because of poor manufacturing processes by a single major supplier. Some people reject this idea and believe that the syndrome is caused by an excess of tryptophan itself (10, 11).
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.

PDGF-BB (Mustoe et al., 1994), FGF-2 (Inadomi et al., 2004), IGF I and II (Zhao et al., 1995), TGF-β (Greenalgh, 1996), and L-arginine (Shi et al., 2003) enhance fibroblast proliferation and deposition of collagen in chronic wounds. Thymosin β4 accelerates wound repair in both young and old diabetic mice by significantly increasing wound contraction and collagen deposition. A synthetic peptide that duplicated the actin-binding domain of thymosin β4 promoted wound repair in aged mice to a degree comparable to that of the whole molecule (Philp et al., 2003). In rats with wound healing impaired by mitomycin C, the formation of granulation tissue (angiogenesis and fibroblast proliferation) was significantly advanced by hydrogel sheets composed of alginate, chitin/chitosan, and fucoidin (Murakami et al., 2010).
In humans, 5-HTP is the nutrient precursor to the neurotransmitter serotonin – widely known as the 'happy neurotransmitter' – meaning 5-HTP converts directly into serotonin in the brain. As well as being in our bodies, it's found naturally in the seeds of a woody shrub native to West Africa. By taking it as a supplement, in theory, you will end up with more serotonin in your brain. Serotonin deficiency is linked to depression, anxiety and a whole host of physical and mental ailments. Raising its levels seems to help brain cells send and receive chemical messages, which in turn boosts mood.

Osteoclast differentiation was assessed by tartrate-resistant acid phosphatase (TRAP) staining and activity. After 5 days of culture, cells were stained for TRAP kit using a leukocyte acid phosphatase kit (Sigma Aldrich, St Louis, MO, USA). Cells with three or more nuclei were counted as multinucleated mature osteoclasts. To measure TRAP activity, cells were fixed with 10% formalin for 10 min and 95% ethanol for 1 min, and then 100 μl of citrate buffer (50 mM, pH 4.6) containing 10 mM sodium tartrate and 5 mM p-nitrophenylphosphate (Sigma-Aldrich) was added to the wells containing fixed cells in the 48-well plates. After incubation for 1 h, enzyme reaction mixtures in the wells were transferred to new plates containing an equal volume of 0.1 N NaOH. Absorbance was measured at 410 nm using a microplate reader.
Melanotan II is a synthetic analogue of the α-melanocyte stimulating hormone (α-MSH). α-MSH is a melanocortin I receptor agonist which has a role in human pigmentation by stimulating production of eumelanin. Melanotan II was originally developed as a treatment for sexual dysfunction. However, the proposal was abandoned when development of the metabolite bremelanotide was established.
Letdown reflex in lactating (breastfeeding) mothers, oxytocin acts at the mammary glands, causing milk to be 'let down' into a collecting chamber, from where it can be extracted by sucking at the nipple. Sucking 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.
Such tissue-regenerating properties of thymosin β4 may ultimately contribute to repair of human heart muscle damaged by heart disease and heart attack. In mice, administration of thymosin β4 has been shown to stimulate formation of new heart muscle cells from otherwise inactive precursor cells present in the outer lining of adult hearts,[18] to induce migration of these cells into heart muscle[19] and recruit new blood vessels within the muscle.[20]
In humans, oxytocin is thought to be released during hugging, touching, and orgasm in both genders. In the brain, oxytocin is involved in social recognition and bonding, and may be involved in the formation of trust between people and generosity.123 Oxytocin first became of interest to researchers when they discovered that breastfeeding women are calmer when exercising and experiencing stress than moms who were bottle-feeding. It is just one part of the important, complex neurochemical system in our bodies that helps us adapt to emotional situations.
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
One study investigating romantic stress that looked at nondepressed youth who went through a recent breakup and were given 60mg of Griffonica Simplicifonia (12.8mg 5-HTP) twice a day for 6 weeks in an open-label study noted reductions in percieved romantic stress when measured at the 3 week mark with no further improvement at 6 weeks; there was no control nor placebo group in this study.[29]

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.
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]
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!
In 2015 I found my self bed ridden for 8 weeks with an issue all the doctors I had been to we’re unable to diagnose. I discovered, after much research, that what I was suffering from was damaged facia in my left and right gluteus muscles, which left me unable to do anything. I was in excruciating pain and couldn’t do anything except lay in bed on my back. Then my husband found TB 500. Initially I was against using it but after deteriorating to the point of being bed ridden I broke down and ordered some. As soon as I received it my husband injected me in the gluteus muscle. Within 30 minutes I started getting relief from the TB-500, within 8 weeks I was out of bed and the pain was gone! It healed the damaged fascia covering the gluteus. If I had not done this I don’t know where I would be today. For me, TB-500 was a life saver and if I had to I would use it again. I have suffered no side affects then or now.
Affecting generosity by increasing empathy during perspective taking: In a neuroeconomics experiment, intranasal oxytocin increased generosity in the Ultimatum Game by 80%, but had no effect in the Dictator Game that measures altruism. Perspective-taking is not required in the Dictator Game, but the researchers in this experiment explicitly induced perspective-taking in the Ultimatum Game by not identifying to participants into which role they would be placed.[89] Serious methodological questions have arisen, however, with regard to the role of oxytocin in trust and generosity.[90] Empathy in healthy males has been shown to be increased after intranasal oxytocin[88][91] This is most likely due to the effect of oxytocin in enhancing eye gaze.[92] There is some discussion about which aspect of empathy oxytocin might alter – for example, cognitive vs. emotional empathy.[93] While studying wild chimpanzees, it was noted that after a chimpanzee shared food with a non-kin related chimpanzee, the subjects' levels of oxytocin increased, as measured through their urine. In comparison to other cooperative activities between chimpanzees that were monitored including grooming, food sharing generated higher levels of oxytocin. This comparatively higher level of oxytocin after food sharing parallels the increased level of oxytocin in nursing mothers, sharing nutrients with their kin.[94]
The PDLCs were pre-treated with Wnt5a siRNA (30 nM) or Wnt5 peptide (500 ng/mL) for 2 hours, post-incubated with Tβ4 peptide (1 μg/mL) and 200 μM H2O2 for 48 hours (A-E), and then conditioned medium (CM) was collected. The bar graph shows the fold increase in protein or mRNA expression compared with control. * Statistically significant differences compared with the control, p<0.05. # Statistically significant difference compared with the H2O2-treated group. The data presented were representative of three independent experiments.
Children: 5-HTP is POSSIBLY SAFE when taken by mouth appropriately. Doses of up to 5 mg/kg daily have been used safely for up to 3 years in infants and children up to 12 years-old. As with adults, there is also concern about the potential for eosinophilia-myalgia syndrome (EMS) in children, a serious condition involving extreme muscle tenderness (myalgia) and blood abnormalities (eosinophilia).
