Oxytocin is not only correlated with the preferences of individuals to associate with members of their own group, but it is also evident during conflicts between members of different groups. During conflict, individuals receiving nasally administered oxytocin demonstrate more frequent defense-motivated responses toward in-group members than out-group members. Further, oxytocin was correlated with participant desire to protect vulnerable in-group members, despite that individual's attachment to the conflict.[64] Similarly, it has been demonstrated that when oxytocin is administered, individuals alter their subjective preferences in order to align with in-group ideals over out-group ideals.[65] These studies demonstrate that oxytocin is associated with intergroup dynamics. Further, oxytocin influences the responses of individuals in a particular group to those of another group. The in-group bias is evident in smaller groups; however, it can also be extended to groups as large as one's entire country leading toward a tendency of strong national zeal. A study done in the Netherlands showed that oxytocin increased the in-group favoritism of their nation while decreasing acceptance of members of other ethnicities and foreigners.[66] People also show more affection for their country's flag while remaining indifferent to other cultural objects when exposed to oxytocin.[67] It has thus been hypothesized that this hormone may be a factor in xenophobic tendencies secondary to this effect. Thus, oxytocin appears to affect individuals at an international level where the in-group becomes a specific "home" country and the out-group grows to include all other countries.
Other supplements are available which have appetite supressant and mood enhancing effects similar to 5-HTP. These type of ingredients are often included, in optimal pre-formulated dosages in fat burners. Phenylethylamine is also another ingredient with mood enhancing potential that is often found in fat burners in place of 5-HTP. 5-HTP can be found in some sleep supplements, though in Australia they are replaced by ingredients such as GABA and phenibut.

In a landmark 1979 study3, Cort Pedersen and Arthur Prange at the University of North Carolina in Chapel Hill showed that giving oxytocin to virgin rats could trigger maternal behaviours: the animals would build nests, lick or crouch over unfamiliar pups and even return lost pups to the nest. Researchers went on to show that oxytocin signalling in the brains of prairie voles (Microtus ochrogaster) helps the animals to form lifelong pair bonds4 — a rarity among mammals. In 2012, researchers even found a version of oxytocin in the tiny roundworm Caenorhabditis elegans, where it helps the animals find and recognize mates5.
Affecting generosity by increasing empathy during perspective taking. In a neuroeconomics experiment, intranasal oxytocin increased generosity in the Ultimatum Game by 80% but has no effect in the Dictator Game that measures altruism. Perspective-taking is not required in the Dictator Game, but the researchers in this experimental explicitly induced perspective-taking in the Ultimatum Game by not identifying to participants which role they would be in.[20]
Reconstituting tanning peptide is a part of the process required for use of the product and will require full attention to get proper results. 1 or 2ml sterile water is usually used, diluting with more water will improve dosing accuracy. Lovemelanotan peptide calculator is ideal tool for anyone just starting out and not sure how to reconstitute or dose the product properly.
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 [19] and endotoxin-induced septic shock of rats [39]. ROS were generated predominantly by polymorphonuclear leukocytes (PMN) during an inflammatory response and involved in tissue destruction associated with periodontal diseases [40]. 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 [41] and implicated in the pathogenesis of rheumatoid arthritis and periodontitis [29].

The biologically active form of oxytocin, commonly measured by RIA and/or HPLC techniques, is also known as the octapeptide "oxytocin disulfide" (oxidized form), but oxytocin also exists as a reduced straight-chain (non-cyclic) dithiol nonapeptide called oxytoceine.[120] It has been theorized that oxytoceine may act as a free radical scavenger, as donating an electron to a free radical allows oxytoceine to be re-oxidized to oxytocin via the dehydroascorbate / ascorbate redox couple.[121]
The soluble form of Ac-SDKP peptide, derived from thymosin beta-4, has been described as a natural inhibitor of pluripotent hematopoietic stem cell proliferation and as a stimulator of angiogenesis, both in vitro and in vivo (Koutrafouri et al., 2001; Wang et al., 2004). This peptide has been selectively bound to acrylated hyaluronic acid hydrogels via thiol groups from cysteine residues (Song et al., 2014). Unfortunately, the immobilization process was poorly characterized and the effect of hydrogels on EC function was not tested in vitro. In a mouse model of chronic myocardial infarction, hydrogels with immobilized Ac-SDKP did not show improved regeneration potential. Yet, Ac-SDKP-HA hydrogels with entrapped stem cell homing factor SDF-1 showed a significant increase of myocardial regeneration and recovery of heart function, as compared to groups with only one or none of these factors, suggesting a potentially interesting synergistic effect.

Pull 1ml of water into the syringe and inject it into the vial with powder. You should never shake the vial when mixing. You should not inject the water directly into the powder with force, but rather let it gently slide down the inside of the vial. If it bubbles up, you should put the vial in the refrigerator and leave it there for about 15-30 minutes. The bubbles will be gone by then. You should then gently rotate the vial between your fingers until all of the powder has dissolved (it takes about 3-4 minutes).
In all groups, [intravenous tryptophan] impaired memory and psychomotor performance significantly. In conclusion, cognitive deficits in [bipolar patients] following [intravenous tryptophan] may reflect a central 5-HT vulnerability in frontal brain areas. Independent of [intravenous tryptophan], cognitive deficits in [bipolar patients] provide evidence for a trait marker for [bipolar disorders].
Oxytocin in a nine amino acid peptide that is synthesized in hypothalamic neurons and transported down axons of the posterior pituitary for secretion into blood. Oxytocin is also secreted within the brain and from a few other tissues, including the ovaries and testes. Oxytocin differs from antidiuretic hormone in two of the nine amino acids. Both hormones are packaged into granules and secreted along with carrier proteins called neurophysins.
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]
Though it may be unlikely to form part of any official psychiatric programme in the UK, Phil Cowen, Professor of Psychopharmacology at Oxford University, admitted that there are various groups for whom it could be helpful. "About half of people with severe depression never see a doctor anyway, so it's reasonable to think it's fine for them to treat themselves with something like a supplement. Perhaps if you had mild symptoms, a smaller dose would be helpful. I'd also prefer to prescribe things like exercise or computer-based CBT if it's that stage, though. But depression and anxiety is very different between people, that's important to keep in mind. No treatment is the same for anyone."
A study using an oral cavity spray of 5-HTP (via the plant source of Griffonia Simplicifolia) has noted that 7.68mg of 5-HTP via 30.72mg of Griffonia Simplicifolia extract taken five times daily (total daily dose of around 40mg) has confirmed an increase in urinary 5-HIAA (from 3.71+/-1.27mg/24 hours to 8.80+/-4.02mg/24 hours; a 137% increase) relative to baseline, confirming that 5-HTP can be absorbed sublingually.[3] Similar results have been noted elsewhere with this spray, although it should be noted that it is confounded with other herbs (detailed in the appetite subsection).[2]
Its unique potential as a healing substance lies in that it interacts with cellular actin and regulates its activity. Tb4 prevents actin from assembling (polymerizing) to form filaments but supplies a pool of actin monomers (unpolymerized actin) when a cell needs filaments for its activity. A cell cannot divide if actin is polymerized. Tb4 therefore serves in vivo to maintain a reservoir of unpolymerized actin that will be put to use when cells divide, move and differentiate.

This article is authored by a PhD Candidate and her supervisory team at University of Queensland, and reflects the interests of the student’s doctoral project in undertaking the nation’s first qualitative study into experiences of Melanotan use among the general population. Dubbed ‘Project Melanotan’, the investigation aims to directly engage with ‘melanotanners’ in a non-judgemental environment, in an effort to both critically evaluate as well as understand lived experiences of melanotaning as they relate to conceptually relevant notions of risk, technology and the body.

Indeed, the findings that progenitor cells of some form exist both in the regenerative zebrafish heart, and in the hearts of less-regenerative mammals supports this idea. Zebrafish have ostensibly found some method to optimize the activity of progenitor cells, perhaps either by maintaining more cells, or by harboring a more cultivating environment for regeneration. Also, both mammalian and nonmammalian hearts contain an epicardial cell layer, yet zebrafish have found some way to activate the epicardium after injury, a process linked with essential neovascularization of regenerating muscle (Lepilina et al., 2006. This result points to the adult mammalian epicardium as a potential cellular source to assist myocardial regeneration or survival. Indeed, mammalian myocardial infarcts typically show poor or insufficient neovascularization, a response that many are trying to improve experimentally. Recent findings have indicated that the G-actin sequestering protein, Thymosin-ß4, may influence the mammalian epicardium. Treatment of adult cardiac explants with Thymosin-ß4 induced the migration of fibroblasts, endothelial and smooth muscle cells as assessed by gene expression and cellular morphology (Smart et al., 2007). In addition, in vivo Thymosin-ß4 treatment could partially restore cardiac survival and function following coronary ligation (Bock-Marquette et al., 2004). Notably, Thymosin-ß4 expression is induced in the injured zebrafish heart, suggesting that fish naturally release this epicardial stimulant on injury (Lien et al., 2006).
The activity of the PAM enzyme system is dependent upon vitamin C (ascorbate), which is a necessary vitamin cofactor. By chance, sodium ascorbate by itself was found to stimulate the production of oxytocin from ovarian tissue over a range of concentrations in a dose-dependent manner.[23] Many of the same tissues (e.g. ovaries, testes, eyes, adrenals, placenta, thymus, pancreas) where PAM (and oxytocin by default) is found are also known to store higher concentrations of vitamin C.[24]
Hey I have used Tb 500 alot and can tell you injecting it in your fat around your stomach or in your large muscles near the injury is fine. I would never inject it into a wounded area because of possiblity of making the area worse by infection or trama from the needle. Dosage is tough I would say for a 200 pound person you need at least 5mg twice a week. Mixing it with GH releasing peptides seems to make it stronger as well. It’s definitely worth the month just finding legit stuff can be tricky.

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 compressing the areola and 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.

Thymosin beta 4 (Tβ4) is a highly conserved, naturally occurring, water-soluble regenerative peptide that is found in all tissues and in all cell types, except red blood cells (Goldstein, Hannappel, Sosne, & Kleinman, 2012; Goldstein & Kleinman, 2015). It is also found in the blood and in other body fluids, including tears, saliva, cerebrospinal fluid, and wound fluids (Badamchian et al., 2007; Huang, Wang, Barnes, & Elmets, 2006; Mohring, Kellmann, Jurgens, & Schrader, 2005). Both platelets and leukocytes release Tβ4 into the wound fluid such that the final concentration is 13 μg/mL (Fromm, Gunne, Bergman, et al., 1996; Hannappel & van Kampen, 1987).
I was kind of scared because I ran across some threads that said TB500 leads to cancer or promotion of benign tumors…most of these were at least 4-5 years old though and it seems there are countless logs online all with good experiences. Nonetheless I was still worried so I did some more research and came across a pharmaceutical company in the US doing clinical trials for thymosin beta 4 to help with dry eye syndrome. I have attached some links. This makes me feel much safer but if you have any more insight I’d really appreciate it.
Oral 5-HTP results in an increase in urinary 5-HIAA, a serotonin metabolite, indicating that 5-HTP is peripherally metabolized to serotonin, which is then metabolized. This might cause a false positive test in tests looking for carcinoid syndrome.[28][29] Due to the conversion of 5-HTP into serotonin by the liver, there could be a risk of heart valve disease from serotonin's effect on the heart, as based on preclinical findings.[30][31] However, 5-HTP has not been associated with cardiac toxicity in humans.[22][32][33][34]
