What we noticed was that all the rats that had received oxytocin straight into their brain immediately prior to being given alcohol, were up and moving about and seemed to be completely sober. Whereas all of the rats that had just been given the alcohol were, as we would predict from the dose that we were giving them, quite drunk. And so we thought, 'Wow, what's going on here?' It was almost as though the oxytocin was blocking the intoxicating effects of the alcohol.
Much of human behavior is influenced by hormones. There’s cortisol, involved in our stress response and energy balance. Testosterone, a male sex hormone, tends to make men more competitive. Oxytocin has various social and physiological functions in the brain and the body, but is sometimes referred to as the “love hormone” due to its role in social bonding. These are all simplifications, but hormones do underlie many aspects of what we do and what we feel.
Potential side effects of 5-HTP include heartburn, stomach pain, nausea, vomiting, diarrhea, drowsiness, sexual problems, vivid dreams or nightmares, and muscle problems. Because 5-HTP has not been thoroughly studied in a clinical setting, possible side effects and interactions with other drugs are not well known. According to the US National Institute of Health TOXNET, 5-HTP has not been associated with serotonin syndrome or any serious adverse events in humans. Across multiple studies, 5-HTP also been reported to not cause any noticeable hematological or cardiovascular changes. 5-HTP also has not been associated with eosinophilia.
For now, Bartz isn’t sure why oxytocin can have such different effects. Her most educated guess is that the hormone triggers a biased trip down memory lane. Under its influence, people are more likely to remember information about their mother that fits with their current attitudes to relationships. If they are anxious, they’re more likely to remember the negative side of their early life. It’s a reasonable enough idea, and one that Bartz intends to test in the future. It will also be good to repeat the study in a larger group – 31 men make for a relatively small study.
When stressed, individuals become mentally and emotionally overwhelmed quite easily. Although individuals can quickly experience the effects of stress on their mental well-being, physical health is also at risk. Some stress is normal. However, chronic stress levels can increase the risk of heart disease and other serious health complications. Regardless of your personal stressor, it is critical to try managing rising stress levels to protect your current and future health. The following highly effective methods will help everyone unwind and promote a more positive state of mind.
The oxytocin peptide is synthesized as an inactive precursor protein from the OXT gene. This precursor protein also includes the oxytocin carrier protein neurophysin I. The inactive precursor protein is progressively hydrolyzed into smaller fragments (one of which is neurophysin I) via a series of enzymes. The last hydrolysis that releases the active oxytocin nonapeptide is catalyzed by peptidylglycine alpha-amidating monooxygenase (PAM).
Milk ejection reflex/Letdown reflex: in lactating (breastfeeding) mothers, oxytocin acts at the mammary glands, causing milk to be 'let down' into subareolar sinuses, from where it can be excreted via the nipple. Suckling 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.

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. As melanotan II is a non-specific melanocortin receptor agonist, it has been reported to cause toxicity effects involving the many physiological systems affected by the receptors.
I have taken BPC-157 in conjunction with TB-500 after reading about someone’s experience. I used the BPC-157 at an injury/inflammation site in my shoulder. I have a pain that came out of nowhere and has prevented me from doing bench presses mainly, and shoulder presses. I also got pain when I did external rotation of my shoulder. The BPC-157 gave me good results at 250 mcg twice daily intramuscularly. The pain is not completely gone but it has definitely lessened in severity. I don’t get any pain with a reverse grip press so I have been doing those with light weight and I can now do shoulder presses. BPC-157 really blew me away on how quickly it improved my gut status. For me it only took 4 days of orally dosing with 250 mcg. So I did both the oral and intramuscular daily for a month. Two weeks into the BPC-157 I ordered TB-500 and did 1mg per week subq in my thigh because I didn’t know about injecting intramuscularly at the injury site.
It has been shown that oxytocin differentially affects males and females. Females who are administered oxytocin are overall faster in responding to socially relevant stimuli than males who received oxytocin. Additionally, after the administration of oxytocin, females show increased amygdala activity in response to threatening scenes; however, males do not show increased amygdala activation. This phenomenon can be explained by looking at the role of gonadal hormones, specifically estrogen, which modulate the enhanced threat processing seen in females. Estrogen has been shown to stimulate the release of oxytocin from the hypothalamus and promote receptor binding in the amygdala.
At least one study has actively differentiated between 'an increase in satiety' (sensation of fullness from food) and a 'decrease in appetite' (less desire to eat) and noted that 5-HTP causes an increase in satiety without a concomitant decrease in appetite. Additionally, most studies are in exclusively females which may have more significance with interventions pertaining to serotonin metabolism; only one study mentioned above was conducted in men as well but appears to suggest that it benefits both genders.
“Shortly after taking the supplement, my vision changes. Colours appear more vivid, I feel lightheaded and generally at ease. My mind calms down and the racing thoughts stop. Today is the 3rd day and I’ve noticed the intensity has gone up and it almost feels like I’m tripping on something. The sky looked absolutely amazing today, colours are so intense but I feel a kind of ungrounded and odd, but still pretty mellow with no anxious thoughts or anything like that which is good.”
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.
Mental health is so under-funded in the UK that pills can be used as the quick-fix option. In 2014/15, 57.8million prescriptions for antidepressants or SSRIs are filled out in England alone. You can wait months on a waiting list for cognitive behavioural therapy or to see a psychiatrist, and as you wait, medication is a lifeline. In addition to this mess, pharma giants have stopped looking for the 'next Prozac', cutting funding into new treatments by 70 percent in the last decade. The bottom line is clear: SSRIs, with all their pros and cons, are here to stay.
“The study was double-blinded and was for two consecutive 6-wk periods. No diet was prescribed during the first period, a 5040-kJ/d diet was recommended for the second. Significant weight loss was observed in 5-HTP-treated patients during both periods. A reduction in carbohydrate intake and a consistent presence of early satiety were also found. These findings together with the good tolerance observed suggest that 5-HTP may be safely used to treat obesity.”
Don’t take it by itself, you want to take it with a meal. The half life seems to vary; some people just need to take a single dose daily whereas some break it up into several doses. The dosage range is pretty wide, from 50 to 900 milligrams. Many report the antidepressant effect desired from lower doses, so start low with this one. Do not use a liquid form of 5-HTP.

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.
Although research has shown that good communication predicts relationship success, successful communication in couples therapy won’t ensure that partners stay together. The goal is to help the two people understand each other’s point of view and come to a mutual decision, even if it’s to break up. “If people are not connected at all, then oxytocin is not going to force that connection,” Guastella says.
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.
Froemke's and Tsien's work fits into a broader theory: that one way oxytocin helps social interaction and recognition is by enhancing the brain's response to socially relevant sights, sounds or other stimuli. Young has shown that the hormone helps mice to recognize and pay attention to the smells of other mice7; others found that it promotes people's ability to recognize faces8.
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.
