The idea that oxytocin is central to social cognition made it an attractive candidate for treating psychiatric disorders, especially autism spectrum disorder. People with this condition, who often have problems with social interaction and communication, may not process social stimuli appropriately — and scientists theorized that oxytocin might reverse some of the symptoms. Beginning in 2010, results emerged that seemed to support this theory: researchers found that single puffs of oxytocin could temporarily improve measures of empathy and social cooperation in people with autism spectrum disorder.
Oxytocin is relatively safe when used at recommended doses. Potential side effects include: Central nervous system: Subarachnoid hemorrhage, seizures; Cardiovascular: Increased heart rate, blood pressure, systemic venous return, cardiac output, and arrhythmias;Genitourinary: Impaired uterine blood flow, pelvic hematoma, tetanic uterine contractions, uterine rupture, postpartum hemorrhage.
There is no long-term side effects ever reported, but there is post injection effects while using Melanotan 2, typically these effects appear during the first few days of dosing and will become increasingly less obvious as the body adjusts to the peptide. These effects include: hot flush in face, mild nausea, decreased appetite, and increased sex drive. In order to combat nausea, an anti-histamine product can be taken until the body gets used to it. But most common way to deal with this is to take the dose before bed.
The reality is that people are always going to self-medicate. Boots, Amazon and H&B all sell 5-HTP, and in theory you could keep buying it and taking it for as long as you like. But it's important to know the facts. It shouldn't be used in conjunction with an SSRI, for example. In that situation, if the body is preventing serotonin breakdown while also getting extra serotonin, which leads to seriously unhealthy levels of serotonin activity.
This is a great product, I have been having digestive problems after 13 major surgeries and suffering from Crohn's Disease my whole life. Currently I can only tolerate a liquid diet. Was very depressed, found this and started taking it and it has made a HUGE difference to my life. Only have very mild depression symptoms now, and sleep better at night. Bought the powder to get the dose right, looks like 100mg suits my 50 kg frame. Only bad thing is the packaging. The 10 grams of powder is lost in the large packet, very hard to get it out and measure the same dose every night. I purchased miniature measuring spoons from ebay and they make life much easier. Sort out the correct spoon for your dosage with the scales then off you go. Can be tricky getting it in and out of the bag, often get powder everywhere, but usually just lick it off. A pill container would work much better for this power.
Bromodeoxyuridine (BrdU), a thymidine analogue, can be incorporated into the DNA of dividing cells and is widely used to label new cells.61-63 To label proliferating cells, BrdU (100 mg/kg) was injected i.p. daily starting at day 1 post TBI for 10 days. The number of BrdU-positive cells found in the ipsilateral cortex, DG, and CA3 areas was significantly increased 35 days after TBI compared with sham controls.18,34,64,65 Tβ4 treatment further increased the number of BrdU-positive cells compared to saline controls.34 The increased number of BrdU-positive cells may result from effects of Tβ4 on either increasing cell proliferation or reducing cell death of newborn cells. Our recent data show Tβ4 increases oligodendrocyte precursor cell proliferation and differentiation in animal models of stroke25 and experimental autoimmune encephalomyelitis.27 Tβ4 may not directly affect cell proliferation but inhibit cell death, for example, in corneal and conjunctival epithelial cells treated with benzalkonium chloride in vitro66 and endothelial precursor cells under serum deprivation.67 Our data further show that neurogenesis increases in TBI rats treated with Tβ4, suggesting that Tβ4 promotes newborn cells to differentiate into neurons. This is consistent with the effect of Tβ4 on promoting epicardium-derived progenitor cell differentiation into endothelial and smooth muscle cells to form the coronary vasculature.22 Whether the increased number of BrdU-positive cells in the brain of TBI rats treated with Tβ4 is tissue specific remains unknown. Tβ4 may not directly affect cell proliferation. Increased cell proliferation and neurogenesis are also possibly secondary to that Tβ4-mediated angiogenesis, as described later.

Studies on diabetic rats indicated significant increases in the amount of collagen and in tensile strength of light-treated wounds over controls (Stadler et al., 2001; Reddy et al., 2001). In combination with hyperbaric oxygen, light-treated skin wounds in rats closed faster (Yu et al., 1997), an effect that was associated with a more uniform rise and fall in VEGF and FGF-2 instead of the sharp peaks at day four and subsequent rapid drop-off observed in control wounds (Whelan et al., 2001). In vitro, proliferation of mouse fibroblasts was increased by over 150% and that of human epithelial cells by 155–171% (Whelan et al., 2001). Whelan et al. (2001) also reported that wound-healing time was decreased by 50% aboard a submarine, where the atmosphere is lower in oxygen and higher in carbon dioxide, and that children suffering from oral mucositis as a result of chemotherapy experienced a 47% reduction in pain. Recently, however, a randomized trial using a 980 nm diode laser to treat venous leg ulcers of 18 patients indicated no difference in reduction of ulcer size compared to the 16 control patients (Leclere et al., 2010).
However, as I’ve said elsewhere, depression is kind of like a check engine light on car, it’s a quiet ambiguous sign that something is not working somewhere in your neurobiology. There is literally dozens (perhaps hundreds) of different ways to attempt to treat depression. Amongst the vast number of options for treating depression, there is a couple of low hanging fruits; things you would want to start with before moving onto more radical options, like…
5-HTP appears to reduce food intake secondary to increasing satiety, although most studies are currently conducted in women (in regards to 5-HTP being related to serotonin, this may be relevant; see our creatine page and the Depression section for more information). At least one study that was mixed gender supports the notion it benefits both genders, however
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.
She recruited 31 men* and asked them to sniff either an oxytocin nasal spray or another spray with the same ingredients minus oxytocin – a placebo. A few weeks later, the sprays were swapped so that the men who took oxytocin now took the placebo, and vice versa. At the time, neither the scientists nor the volunteers knew which was which – that was only revealed after the experiment was over.
Even if you did look after yourself adequately and monitor the amount of 5-HTP you were taking, it doesn't appear to be a permanent or lasting solution. A couple of the doctors talked about something that comes up time and time again with long-term SSRI use: a dissipating effect, meaning they can feel less and less effective over time. It seems that people may have the same problem with 5-HTP. "If you push on your biochemistry hard enough, it may downregulate," Dr Paddock explained. "If you're taking SSRIs your body may downregulate the amount of serotonin it puts out so you get waning effects over time. It's similar with 5-HTP. There may be a certain level of serotonin your body is keeping you at and if you raise it or push it, your body then may say, 'Okay, we're above the set point, let's then raise that point again.'"
I’ve used powdered 5-HTP a couple times now, it doesn’t taste great and it’s resulted in an unpleasant stomach upset that lasted 45–60 minutes. For that reason I’ll likely not continue to use it. I did not find it’s effect on mood remarkable enough that I would want to put up with the stomach upset. My go to Nootropics for mood are Rhodiola and Phenibut and my go to Biohacks for mood are meditation and no fap, I don’t feel the need to use a whole lot more mood promoting strategies.
Expanding upon the possible anti-panic effects of 5-HTP, one study using 2mg/kg 5-HTP to children (3.2-10.6 years of age) at bedtime for 20 days noted that 5-HTP was asssociated with beneficial response (more than 50% reduction in night terror frequency) of 93.5% of children relative to 28.6% in placebo. Oddly, 6 months after the initial supplementation period the 5-HTP group still reported less sleep terrors (83.9% reporting improvement).
Melanotan II has reported toxicity effects from therapeutic and overdose exposures including: renal dysfunction, rhabdomyolysis, sympathomimetic overdrive, change in size and pigmentation of pre-existing moles, rapid increase in the number of new moles associated with causing melanomas, posterior reversible encephalopathy syndrome, refractory priapism, stretching and yawning syndrome, shortness of breath, chest pain, abdominal cramping and pain, dizziness and lethargy. XXXXXX alone has received 28 calls about melanotan II since 2006.
In the experiments, an epithelial wound was made in the corneas of sedated rats. A Tb4 solution was applied at several concentrations to the injured eyes in one group of rats while another group was treated with a solution without Tb4. Following 12, 24 and 36 hours, the eyes were tested by microscopic observation for epithelial growth over the injured site. Investigators found the Tb4 accelerated corneal wound repair at doses of Tb4 similar to those found to repair skin wounds. When tested 24 hours after treatment, the rate of accelerated repair was proportional to the concentration of Tb4, with the highest dose (25 microgram) showing a threefold acceleration of epithelial cell migration, compared to untreated. Treatment with Tb4 showed anti-inflammatory effects, helping resolve the injury. An application to human cells in a model of human corneal cells in culture showed that Tb4 enhanced epithelial cell migration in vitro.
In conclusion, this study is the first study to demonstrate that down-regulation of Tβ4 was observed in an in vitro model of H2O2-stimulated PDLCs. Tβ4 activation had anti-inflammatory effects via MAPK and NF-κB pathways in PDLCs and anti-osteoclastogenic effects via MAPK, NF-κB, and Wnt5a pathways in BMMs. These findings supported the fact that Tβ4 peptide could possibly be used in the development of a therapeutic drug for periodontitis and osteolytic disease.
Who is 5-HTP best for? Emotional eaters stand to benefit greatly, of course. So do carb addicts. Carbs help the body make 5-HTP — so when 5-HTP or serotonin are low, carb cravings kick in. Boosting 5-HTP with a supplement has been shown to slash carb cravings by more than 50 percent. And if a “fat gene” runs in your family, early evidence hints that this genetic tendency toward obesity is linked to “decreased activity of an enzyme that helps turn tryptophan into 5-HTP,” explains Michael T. Murray, ND, author of 5-HTP: The Natural Way to Overcome Depression, Obesity and Insomnia ($14.77, Amazon). Though more human research is needed, Dr. Murray believes 5-HTP supplements are a quick fix for the genetic glitch.
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.
Both the production of oxytocin and response to oxytocin are modulated by circulating levels of sex steroids. The burst of oxytocin released at birth seems to be triggered in part by cervical and vaginal stimulation by the fetus, but also because of abruptly declining concentrations of progesterone. Another well-studied effect of steroid hormones is the marked increase in synthesis of uterine (myometrial) oxytocin receptors late in gestation, resulting from increasing concentrations of circulating estrogen.
It was also shown recently that delivery of Fgfs by release from peptide nanofibers, a gradual local delivery system, can increase neovascularization and reduce in-farct size in the ischemic rodent heart (Engel et al., 2006). Related to this, zebrafish have a natural ability to synthesize Fgfs after myocardial injury, a signal that appears to recruit Fgf receptor-expressing epicardial-derived cells toward regenerating muscle (Lepilina et al., 2006). Thus, what has been and what will be discovered about zebrafish heart regeneration is quite likely to illuminate possible strategies for enhancing regeneration in the mammalian heart (see Chapter 14.4).
About ten years ago, psychology studies started to show that single doses of oxytocin, delivered through an intranasal spray, could promote various aspects of social behaviour in healthy adults. People who inhaled oxytocin before playing an investment game were more willing to entrust their money to a stranger than were placebo-treated players10. A dose of the hormone also increased the amount of time that people spent gazing at the eye region of faces11, and improved their ability to infer the emotional state of others from subtle expressions12.

The peripheral actions of oxytocin mainly reflect secretion from the pituitary gland. The behavioral effects of oxytocin are thought to reflect release from centrally projecting oxytocin neurons, different from those that project to the pituitary gland, or that are collaterals from them. Oxytocin receptors are expressed by neurons in many parts of the brain and spinal cord, including the amygdala, ventromedial hypothalamus, septum, nucleus accumbens, and brainstem.
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.
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).
On the most basic level, a peptide is essentially a small protein. Billions of unique peptides exist, all with different effects and functions in the body. Physiological examples include insulin, oxytocin, and casein, the main protein in milk. Thus, to taunt Essendon supporters for the use of “peptides” is rather non-specific. A much more intelligent insult would be to focus on the administration of thymosin beta-4.
