There have been encouraging results for the use of Tβ4 as a topical gel to treat venous stasis ulcers, a type of wound that develops on the lower leg of patients with chronic vascular disease. Two other reports indicated that Tβ4, formulated in eye-drops, may enhance corneal wound healing in diabetic patients, and improve ocular discomfort. These are the most advanced trials to date. As of yet, despite promising animal models, there has been no significant study exploring the efficacy of intravenous Tβ4 injections in treating ischemic heart injury.
A study published last year in Biological Psychiatry was the first to assess whether people with variations in their oxytocin-receptor gene have a harder time maintaining romantic relationships than those who don’t. Hasse Walum, a graduate student at Karolinska Institute in Stockholm, and his colleagues took advantage of Swedish twin studies that included thousands of participants, their genetic information and their answers to questions about how affectionate they were with their romantic partners. They found that women with a specific variation weren’t as close to their partners as women without it: they kissed their partners less and didn’t desire physical proximity as often. These women were also more likely to report having had a marital crisis. Although researchers don’t know exactly how this variation affects the oxytocin system, it may result in a lower number of oxytocin receptors in the brain. People with fewer receptors would be less sensitive to the hormone’s effects.
Young says that the oxytocin field would benefit from closer collaboration between basic and clinical researchers. If basic scientists can work out how oxytocin helps the brain to process social stimuli, then that might help in the design of stimuli — in the form of behavioural therapies — that could be given alongside the hormone to change behaviour, just as oxytocin and pup calls together affect virgin mice. “I think in the future these two branches need to have more communication,” Young says.
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.

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.
The logic behind this trend is that creating tanned skin (by increasing melanin) with minimal to no sun exposure could protect individuals from skin damage, and even potentially lower melanoma risk. More melanin means more protection from UV radiation, and therefore a healthier (and conveniently, deeper) complexion. In this sense, there is perhaps a kernel of truth to the idea of the “healthy glow”.
"Just that it is completely false that these particular substances and the program wasn't discussed through the highest levels of the club. We have been very firm in terms of our belief in what ASADA, the AFL and Essendon know and for them to remotely suggest that no one knew, to be really blunt, is completely wrong and in some ways offending the process we set up at Essendon Football Club. We were very strict in the protocols we set up."
Melanotan 2 works by stimulating the release of the pigment melanin from the skin. Less UV exposure is necessary with Melanotan 2 compared to “normal tanning”, and the tan that occurs with tanning injections is deeper and longer lasting than an individual’s “normal tan”. Melanotan works best (has the most noticeable effects) on people with fair skin tones.
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. Nasally administered oxytocin has also been reported to reduce fear, possibly by inhibiting the amygdala (which is thought to be responsible for fear responses). There is no conclusive evidence for access of oxytocin to the brain through intranasal administration, however.
According to recent research, this hormone “is now believed to be involved in a wide variety of physiological and pathological functions such as sexual activity, penile erection, ejaculation, pregnancy, uterine contraction, milk ejection, maternal behavior, social bonding, stress and probably many more, which makes oxytocin and its receptor potential candidates as targets for drug therapy. From an innocuous agent as an aid in labor and delivery, oxytocin has come a long way in being touted as the latest party drug.”4
MAPKs and NF-κB played pivotal roles in the development of osteoclasts downstream of RANK signaling . In this study, we demonstrated that Tβ4 activation by Tβ4 peptide inhibited RANKL-induced p38, ERK, JNK MAPK, and NF-κB signaling pathways. These results suggested that Tβ4 activation might inhibit osteoclast differentiation via inhibition of the signaling cascades MAPK/NF-κB/NFATc1.
Thymosin beta 4, developed by RegeneRx Biopharmaceuticals as a pharmaceutical for the healing of wounds, is a synthetic version of the natural peptide. As Dr. Allan Goldstein emphasizes, “Tb4 represents a new class of wound healing compounds. It is not a growth factor or cytokine, but rather exhibits a number of physiological properties which include the ability to sequester and regulate actin, its potent chemotactic properties. . . and its capability to downregulate a number of inflammatory cytokines that are present in chronic wounds.” When a wound heals there are many growth factors produced in the area so that additional factors, such as those currently on the market for wound healing, may help but are not necessarily lacking. Tb4 treatment, however, adds a new dimension to wound repair by providing cells with actin as needed, for cell migration, replication and differentiation.
Hi Ben, I have been using TB-500 for minor injury repair assistance for more than 2 years. I have found it to be extremely effective for minor strains to calves, hamstring, shoulder etc. Luckily I have not had to try it for any major injuries. When I first used it I was blown away by how effectively it worked – even to the point that I began to doubt the seriousness of the original injury. When injured I dose at 5mg per week for four weeks then take at least four weeks break. The only side affect I have noticed is a little light headed feeling which passes pretty quickly. I am in my late 40’s and I train hard. TB-500 allows me to train through minor injuries which is great. Love your work
“I didn’t think it would be that bad honestly, but since I weight lift multiple times a weak, this supplement is doing me more harm than good. On a typical weight lifting day my workout is split into 5 sections. After taking 5-htp the night before I barely have enough energy to get through 1 section, and that is a serious problem, because of this I am quitting 5-htp all together.”
In this study, Tβ4 mRNA down-regulation was detected in in vitro in PDLCs stimulated with the ROS. This down-regulation of Tβ4 was also observed in GCF of periodontitis patient  and endotoxin-induced septic shock of rats . ROS were generated predominantly by polymorphonuclear leukocytes (PMN) during an inflammatory response and involved in tissue destruction associated with periodontal diseases . Thus, we chose to use ROS-stimulated PDLCs in this study since ROS, such as superoxide and H2O2, have been proposed as key players in bone resorption  and implicated in the pathogenesis of rheumatoid arthritis and periodontitis .
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.
Due to its molecular structure and low molecular weight, TB-500 is very versatile, mobile and possesses the ability to travel long distances through tissues. This means that when targeting injured areas (chronic or acute), TB-500 has the ability to circulate through the body and “find” those areas of injury in order to enhance the healing or growth process. Many users have also noted the added benefits of improved flexibility, reduced inflammation in tendons, re-growth of lost hair, and darkening of grayed hair.
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.
Depression. Some clinical research shows that taking 5-HTP by mouth improve symptoms of depression in some people. Some clinical research shows that taking 5-HTP by mouth might be as beneficial as certain prescription antidepressant drugs for improving depression symptoms. In most studies, 150-800 mg daily of 5-HTP was taken. In some cases, higher doses have been used.
Exposure to ultraviolet (UV) light prompts an increased release of Alpha-MSH, which in turn stimulates the production of melanin in the skin. The more melanin produced the greater pigmentation level becomes, making the skin progressively darker and tan lasts significantly longer. This makes Melanotan peptide unique, people do not require as much exposure to UV light to produce more melanin, very attractive for people wishing to develop greater tanning of the skin in fastest way possible.
Kim found that when Americans who carry a particular version of the OXTR gene are more likely to turn to their friends for support when they are distressed. But Koreans react to social stress in a different way – for them, it’s less socially acceptable to turn to friends for support during tough times. And distressed Koreans who carry the same version of OXTR are less likely to seek support from their friends.
