In a study measuring oxytocin serum levels in women before and after sexual stimulation, the author suggests it serves an important role in sexual arousal. This study found genital tract stimulation resulted in increased oxytocin immediately after orgasm.[105] Another study reported increases of oxytocin during sexual arousal could be in response to nipple/areola, genital, and/or genital tract stimulation as confirmed in other mammals.[106] Murphy et al. (1987), studying men, found oxytocin levels were raised throughout sexual arousal with no acute increase at orgasm.[107] A more recent study of men found an increase in plasma oxytocin immediately after orgasm, but only in a portion of their sample that did not reach statistical significance. The authors noted these changes "may simply reflect contractile properties on reproductive tissue".[108]

I had tennis elbow on both arms for over 3 years now. Had one surgery on the R, countless PRPs, and a stem cell treatment on both but still to no avail. Pain on the L never eased up and I just had my 3rd PRP booster injections yesterday after having my stem cells 2 months ago. So can you tell me if BPC 157 or TB 500 better suits my situation. Many thanks!

When you get your TB-500, it will come in a powder form. Just like BPC-157, you will need to “reconstitute” it by adding bacteriostatic water. Go back and read my article on BPC-157 to get access to a peptide calculator that will help you with the mixing/dosage math. Once your TB-500 is properly mixed, you then draw the dose into an insulin syringe, and inject it intramuscularly, subcutaneously, or intravenously (according to your preference).

In a study that hasn’t been published yet, Feldman found that oxytocin receptor genes are also linked to empathy in couples. She looked at variants in the gene that have been linked with an increased risk for autism, a disorder that is marked by major social communication deficits. She found that the more of these “risk variants” a person had, the less empathy they showed toward their partner when that partner shared a distressing experience.

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.

In the hypothalamus, oxytocin is made in magnocellular neurosecretory cells of the supraoptic and paraventricular nuclei, and is stored in Herring bodies at the axon terminals in the posterior pituitary. It is then released into the blood from the posterior lobe (neurohypophysis) of the pituitary gland. These axons (likely, but dendrites have not been ruled out) have collaterals that innervate neurons in the nucleus accumbens, a brain structure where oxytocin receptors are expressed.[31] The endocrine effects of hormonal oxytocin and the cognitive or behavioral effects of oxytocin neuropeptides are thought to be coordinated through its common release through these collaterals.[31] Oxytocin is also produced by some neurons in the paraventricular nucleus that project to other parts of the brain and to the spinal cord.[32] Depending on the species, oxytocin receptor-expressing cells are located in other areas, including the amygdala and bed nucleus of the stria terminalis.

Double immunofluorescent staining for BrdU (red, A) and NeuN (green, B) to identify newborn neurons (yellow after merge, C) in the dentate gyrus of hippocampus from rats examined 35 days after TBI. Micrographs (D) show location of DiI injection in the CA3 region (indicated by white asterisk). In the CA3 region, axons projected from granule neurons in the dentate gyrus will take up injected DiI to their cell bodies. Co-localization (merge, H) of BrdU-positive nuclei (green, F) within retrogradely DiI labeled (red, E) granule cells were examined at 35 days after TBI. Scale bar = 25 μm (C, H). Scale bar = 50 μm (D).
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.

The enzyme dopamine decarboxylase (aromatic L-amino acid decarboxylase) mediates the conversion of 5-HTP into serotonin, and this enzyme is expressed in stomach tissue.[53] Inhibition of this enzyme in the stomach during 5-HTP ingestion is thought to promote the concentration of 5-HTP that reaches neural tissue, which is supported by a study using 100-200mg Carbidopa (pharmaceutical inhibitor) alongside 5-HTP to increase radioactivity of 5-HTP (indicative of neural accumulation) in humans.[54]

PDGF-BB (Mustoe et al., 1994), FGF-2 (Inadomi et al., 2004), IGF I and II (Zhao et al., 1995), TGF-β (Greenalgh, 1996), and L-arginine (Shi et al., 2003) enhance fibroblast proliferation and deposition of collagen in chronic wounds. Thymosin β4 accelerates wound repair in both young and old diabetic mice by significantly increasing wound contraction and collagen deposition. A synthetic peptide that duplicated the actin-binding domain of thymosin β4 promoted wound repair in aged mice to a degree comparable to that of the whole molecule (Philp et al., 2003). In rats with wound healing impaired by mitomycin C, the formation of granulation tissue (angiogenesis and fibroblast proliferation) was significantly advanced by hydrogel sheets composed of alginate, chitin/chitosan, and fucoidin (Murakami et al., 2010).
Virtually all vertebrates have an oxytocin-like nonapeptide hormone that supports reproductive functions and a vasopressin-like nonapeptide hormone involved in water regulation. The two genes are usually located close to each other (less than 15,000 bases apart) on the same chromosome, and are transcribed in opposite directions (however, in fugu,[44] the homologs are further apart and transcribed in the same direction).
5-HTP is converted by the body to serotonin, a chemical in the brain that plays an important role in mood, sleep, and appetite. Many prescription medications used for the treatment of depression increase serotonin concentrations in the brain. Because of 5-HTP's pathway to serotonin, it has appealed to researchers as well as the public as a "natural" alternative to antidepressants and treatment of depression, insomnia, migraines, obesity, and fibromyalgia.

Autism: Oxytocin has been implicated in the etiology of autism, with one report suggesting autism is correlated with genomic deletion of the gene containing the oxytocin receptor gene (OXTR). Studies involving Caucasian and Finnish samples and Chinese Han families provide support for the relationship of OXTR with autism.[55][56] Autism may also be associated with an aberrant methylation of OXTR.[55]
For decades, 5-HTP has been recognized as important to appetite regulation. Higher levels of serotonin are linked to diminished appetite. Keeping serotonin levels from dipping can help keep appetite in check, and may help reduce cravings for carbohydrates. As a serotonin booster, 5-HTP may help to suppress appetite. Research indicates that 5-HTP may be effective in helping people who are overweight or obese lose weight.

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].
Tβ4 is the major monomeric actin-sequestering peptide in human tissues, and can bind globular actin (G-actin) in a 1:1 ratio and consequently involved in cytoskeletal regulation by inhibiting the polymerization of G-actin into fibrous actin (F-actin) [7]. In addition, Tβ4 is an ubiquitous naturally occurring molecule and is found at concentrations of 1 × 10−5 to 5.6 × 10−1 M in a variety of tissues and cell types, yet, no receptors for the protein have been identified [33]. A recent study suggests that internalization of exogenous Tβ4 is essential for its subsequent cellular functions [34]. Moreover, Tβ4 has been shown to be associated with, wound healing, hair growth, immunomodulation, and angiogenesis [7–9].
Autism. A 1998 study found significantly lower levels of oxytocin in blood plasma of autistic children.7 A 2003 study found a decrease in autism spectrum repetitive behaviors when oxytocin was administered intravenously.8 A 2007 study reported that oxytocin helped autistic adults retain the ability to evaluate the emotional significance of speech intonation.9

I have Dupretren’s in my hand. The chords are tightening which is common to this disease pulling the fingers towards the palm. I cannot play guitar any longer. I can still hold a flat palm to the floor when I exercise, but it gets more difficult as the disease takes hold (no pun intended). I’ve read a lot from others inflicted with this. Didn’t like what I read. Hand surgery with modest effects, often adverse effects and too infrequent a fix to the problem. I tried deep tissue massage and scraping too.
Moreover, Tβ4 concentration revealed wide variability, and it decreased in the gingival crevicular fluid (GCF) as periodontal disease progressed [19]. In contrast, Tβ4 mRNA expression was 3.76 fold higher in periodontitis-affected gingival tissue, compared with healthy individuals’ tissue obtained from public microarray data (GEO assession: GSE 23586) [20]. However, the Tβ4 mRNA level did not change in the periodontal-diseased gingival tissue (arbitrary units; 6.249) when compared with healthy tissue (arbitrary units; 6.242) (GEO assession: GSE 10334) [21]. Although Tβ4 exerts anti-inflammatory effects in vivo and in vitro, the precise role of Tβ4 in the inflammatory response remains unclear.
To pursue the sexual dysfunction agent, melanotan-II was licensed by Competitive Technologies to Palatin Technologies.[9] Palatin ceased development of melanotan-II in 2000 and synthesized, patented, and began to develop bremelanotide, a likely metabolite of melanotan-II that differs from melanotan-II in that it has a hydroxyl group where melanotan-II has an amide.[6][13] Competitive Technologies sued Palatin for breach of contract and to try to claim ownership of bremelanotide;[13] the parties settled in 2008 with Palatin retaining rights to bremelanotide, returning rights to melanotan-II to Competitive Technologies, and paying $800,000.[14]
