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.
Oxytocin has been of keen interest to neuroscientists since the 1970s, when studies started to show that it could drive maternal behaviour and social attachment in various species. Its involvement in a range of social behaviours2, including monogamy in voles, mother–infant bonding in sheep, and even trust between humans, has earned it a reputation as the 'hug hormone'. “People just concluded it was a bonding molecule, a cuddling hormone, and that's the pervasive view in the popular press,” says Larry Young, a neuroscientist at Emory University in Atlanta, Georgia, who has been studying the molecule since the 1990s.
Hey mate, I’m getting a shoulder reconstrcution in about 2 weeks. Do you think that TB-500 and BPC-157 would help heal something as complex as this. Or do you think that stacking something like GHRP-6 and CJC-1295 would work better because this would assist in muscle growth and strength gains of surrounding muscles etc. Also if chose to use peptides when do you think I should start using them, I will be in a sling for 6weeks after surgery with only passive movements.
Surgery: 5-HTP can affect a brain chemical called serotonin. Some drugs administered during surgery can also affect serotonin. Taking 5-HTP before surgery might cause too much serotonin in the brain and can result in serious side effects including heart problems, shivering, and anxiety. Tell patients to stop taking 5-HTP at least 2 weeks before surgery.
Oxytocin is a hormone that also acts as a neurotransmitter in the brain. Some popular media have incorrectly labeled it the “love hormone,” because it is associated with good feelings and emotions. But its role in the body is much more complex than that. It is not a bliss or hug hormone, but it does appear to be connected to human emotions and the regulation of childbirth and breast-feeding.
A Risk Quiz; Let’s say you are one of the volunteers to whom researchers gave $100, and this option: you can either keep the money, or give it to an anonymous trustee who will either invest it and double it to $200 and return half of the extra hundred bucks to you–$50–or keep all the money for herself. So you can either increase your money by 50%, or lose it all. What would you do? Would you trust that anonymous trustee? (Remember Loss Aversion from Chapter Two, where in a similar experiment most people decided to avoid the gamble and take the sure cash.)
Trust is increased by oxytocin. Disclosure of emotional events is a sign of trust in humans. When recounting a negative event, humans who receive intranasal oxytocin share more emotional details and stories with more emotional significance. Humans also find faces more trustworthy after receiving intranasal oxytocin. In a study, participants who received intranasal oxytocin viewed photographs of human faces with neutral expressions and found them to be more trustworthy than those who did not receive oxytocin. This may be because oxytocin reduces the fear of social betrayal in humans. Even after experiencing social alienation by being excluded from a conversation, humans who received oxytocin scored higher in trust on the Revised NEO Personality Inventory. Moreover, 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 they were interacting with a computer showed no such reaction, leading to the conclusion that oxytocin was not merely affecting risk aversion. When there is a reason to be distrustful, such as experiencing betrayal, differing reactions are associated with oxytocin receptor gene (OXTR) differences. Those with the CT haplotype experience a stronger reaction, in the form of anger, to betrayal.
The cornea is the outer thin layer of epithelial cells protecting the eye. After wounding, timely resurfacing of the cornea with new cells is critical, to prevent loss of normal function and loss of vision. Corneal epithelial healing occurs in stages, with cells migrating, dividing and differentiating. Therapies for corneal injury are limited. Therefore, the recent finding that Tb4 promotes corneal wound repair in animal models offers hope for a therapeutic product that will improve the clinical outcome of patients with injured corneas.
5-HTP increases a brain chemical called serotonin. Taking 5-HTP along with other herbs and supplements that increase serotonin might lead to too much serotonin and cause side effects including heart problems, shivering and anxiety. Other herbs and supplements that increase serotonin levels include Hawaiian baby woodrose, L-tryptophan, S-adenosylmethionine (SAMe), and St. John's wort.
Treatment with thymosin beta 4 (Tβ4) reduces infarct volume and preserves cardiac function in preclinical models of cardiac ischemic injury. These effects stem in part from decreased infarct size, but additional benefits are likely due to specific antifibrotic and proangiogenic activities. Injected or transgenic Tβ4 increase blood vessel growth in large and small animal models, consistent with Tβ4 converting hibernating myocardium to an actively contractile state following ischemia. Tβ4 and its degradation products have antifibrotic effects in in vitro assays and in animal models of fibrosis not related to cardiac injury. This large number of pleiotropic effects results from Tβ4’s many interactions with cellular signaling pathways, particularly indirect regulation of cellular motility and movement via the SRF–MRTF–G-actin transcriptional pathway. Variation in effects and effect sizes in animal models may potentially be due to variable distribution of Tβ4. Preclinical studies of PK/PD relationships and a reliable pharmacodynamic biomarker would facilitate clinical development of Tβ4.
There is one glaring problem, however: the supplements come with a disclaimer that recommends not taking them for more than three months. Most of the information out there on 5-HTP is anecdotal, and most of them are stories of it helping people, rather than hard facts about its scientific properties. I approached neurologists, psychologists and experimental doctors about 5-HTP, and many responses were strange. Not many people were willing to speak about it, saying they weren't qualified or hadn't read the relevant material, but there isn't much material to speak of. The main source of legitimate scientific evidence came from the University of Maryland Medical Center website, who stated that 5-HTP may work as well as certain antidepressant drugs to treat people with mild-to-moderate depression. But all the studies that support that statement were done in the 1980s and 1990s. I wanted to know if 5-HTP was a realistic alternative to SSRIs. Could I stay on 5-HTP forever, basking in its natural glory?
The RANKL and OPG have been identified as a key regulatory component of alveolar bone loss associated with inflammatory periodontal disease . Moreover, PDLCs were shown to express several osteoclastogenic cytokines, including both OPG and RANKL [30, 31]. Our data demonstrated that Tβ4 peptide abolished H2O2-induced RANKL expression and restored OPG expression. Osteoclasts, bone-resorptive multinucleated cells derived from hematopoietic stem cells, are associated with osteolytic diseases. Furthermore, NFATc1, a master modulator of osteoclastogenesis, regulates target genes, such as cathepsin K and calcitonin receptor or Calcr . In our in vitro study using BMMs, Tβ4 peptide directly and indirectly inhibited RANKL-induced osteoclast differentiation and expression of osteoclast markers, such as cathepsin-K, calcitonin receptor or Calcr, NFATc1, and RANK in BMM cells. These results indicated that Tβ4 was a key therapeutic target in controlling inflammation-induced bone loss.
5-HTP has been shown in scientific studies to promote relaxation and alleviate stress and anxiety. The relaxation and anti-anxiety properties of 5-HTP appear to come from its ability to elevate levels of serotonin. Research has demonstrated that 5-HTP may reduce the risks of panic attacks and symptoms of panic, as well as anxiety and emotional stress. Research also indicates 5-HTP may be effective in helping to alleviate depression.
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. 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 as assessed by a Flashmark Pro recording device.
Side effects: Nausea, fatigue, facial flushing, reaction at injection site, appetite suppression. The potential for side effects to occur increases with an increased dose of Melonotan, and decreases both with a lesser dose and with regular administration. The exception to this is physical signs of sexual arousal, namely male erection when using MT2. So it is important that users of MT II are aware of this before administering.
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!
Bartz found that when she averaged out the volunteers’ results, the sniffs of oxytocin hadn’t seemed to colour their memories of their mothers. But things changed when she looked at them individually. Those who felt more anxious about their relationships took a dimmer view of their mother’s parenting styles when they sniffed oxytocin, compared to the placebo. Those who were more secure in their relationships reacted in the opposite way – they remembered mum as being closer and more caring when they took the oxytocin.
Evidence for this role of oxytocin come from two types of experiments. First, infusion of oxytocin into the ventricles of the brain of virgin rats or non-pregnant sheep rapidly induces maternal behavior. Second, administration into the brain of antibodies that neutralize oxytocin or of oxytocin antagonists will prevent mother rats from accepting their pups. Other studies support the contention that this behavioral effect of oxytocin is broadly applicable among mammals.
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.
Sexual activity: The relationship between oxytocin and human sexual response is unclear. At least two uncontrolled studies have found increases in plasma oxytocin at orgasm – in both men and women. Plasma oxytocin levels are notably increased around the time of self-stimulated orgasm and are still higher than baseline when measured five minutes after self arousal. The authors of one of these studies speculated that oxytocin's effects on muscle contractibility may facilitate sperm and egg transport.
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.
Ive been struggling with my left brachialis and so after listening to a podcast in which you mentioned BPC-157 I tried it out. I was hoping for a miracle cure, which I did not get. However, I believe it certainly helped a lot. I am considering a second round. But the peptide rabbit hole is certainly interesting and I am most keen to try some others. But I would like to see if you have some advise for me on another topic. After having listened to your podcast with Dr Gains I thought that either you or Dr Gains may be able to at least point me in the right direction. My wife suffers from a condition called Pelvic Vein Congestion which causes her a lot of pain. From what I understand, she has a seemingly unnatural mass of veins around her uterus which may also suffer from a “valve” type problem in which blood can potentially run in the opposite direction and pool in locations which causes pain. She has been to doctors which offer invasive solutions with unattractive success rates. I have been searching for other cures, but the only thing that I found (supplement with Diosmin and Hisperidan) had some psychological effects. Any thoughts?
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.
Obesity. Early research suggests that taking 5-HTP might help reduce appetite, caloric intake, and weight in obese people. Other research suggests that using a specific mouth spray containing 5-HTP and other extracts (5-HTP-Nat Exts, Medestea Biotech S.p.a., Torino, Italy) for 4 weeks increases weight loss by about 41% in overweight postmenopausal women.
