For all its positivity, however, oxytocin has a dark side. Or, more accurately, it plays a more complex role in human behavior than is commonly thought. As a facilitator of bonding among those who share similar characteristics, the hormone fosters distinctions between in-group and out-group members, and sets in motion favoritism toward in-group members and prejudice against those in out-groups. Ongoing research on the hormone is a potent reminder of the complexity of biological and psychological systems.
There have been some side effects reported 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: nausea, appetite loss, drowsiness and increased sex drive. In order to combat nausea, an anti-histamine can be taken when injecting until the body gets used to it. But most common way to deal with this is to inject Melanotan before bed, this is also beneficial to combat any drowsiness.
To evaluate the indirect effect of Tβ4 peptide on RANKL-induced osteoclastogenesis, mouse BMMs were incubated with RANKL and CM, prepared from HPDLCs treated with H2O2 and different concentrations of Tβ4, and allowed to differentiate into osteoclasts. As shown in Fig 6, Tβ4 peptide dose-dependently decreased the number of osteoclasts and TRAP activity. To determine whether the reduction in osteoclast generation by Tβ4 could be due to effects of Tβ4 peptide on viability of the BMMs, a cytotoxicity assay was performed. The viability of BMMs was not significantly affected by Tβ4 peptide (data not shown).
Children: 5-HTP is POSSIBLY SAFE when taken by mouth appropriately. Doses of up to 5 mg/kg daily have been used safely for up to 3 years in infants and children up to 12 years-old. As with adults, there is also concern about the potential for eosinophilia-myalgia syndrome (EMS) in children, a serious condition involving extreme muscle tenderness (myalgia) and blood abnormalities (eosinophilia).
5-HTP has been linked in very rare instances to a condition known as EMS, or eosinophilia-myalgia syndrome, which combines extreme muscle tenderness with abnormalities in the blood. A contaminant that was found in some tryptophan supplements in the late 1980s, and was linked to a small number of EMS cases, was also found in some 5-HTP supplements.  It’s important to talk with your doctor before you begin taking 5-HTP or any other supplement, and to make sure you’re getting your supplements from a reliable provider.

In the ER, the patient's heart rate was elevated, she was sweaty, and had some muscle spasms. The physician in the ER called Poison Control for guidance. Poison Control indicated that a drug interaction between 5-HTP and Zoloft was a likely cause of the patient's symptoms because they were consistent with a rare but serious condition (serotonin syndrome) that occurs when serotonin concentrations in the brain are too high. Poison Control recommended a sedative to decrease the patient's heart rate and improve the other symptoms.

The main functionality of TB500 hinges on the ability to upregulate cell building proteins such as actin, which is a protein that forms (together with myosin) the contractile filaments of muscle cells, and is also involved in motion and metabolism in many other types of cells.. Upregulation of actin allows TB500 to promote healing, cell growth, cell migration and cell proliferation. This not only helps build new blood vessel pathways but also upregulates the type of “good” inflammation that is directly correlated with faster wound healing.

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.[42] Oddly, 6 months after the initial supplementation period the 5-HTP group still reported less sleep terrors (83.9% reporting improvement).[42]


One study investigating romantic stress that looked at nondepressed youth who went through a recent breakup and were given 60mg of Griffonica Simplicifonia (12.8mg 5-HTP) twice a day for 6 weeks in an open-label study noted reductions in percieved romantic stress when measured at the 3 week mark with no further improvement at 6 weeks; there was no control nor placebo group in this study.[29]
About three months after quitting, I did have a major relapse, which was falling back into old habits for about two weeks. And the whole time I knew what was happening, I knew how dangerous it was, but I couldn't stop myself. I felt like I couldn't connect to anyone without drinking. I couldn't talk to my friends, I couldn't be open and honest with anybody in my life without already having had a few drinks. It was a really disconnected, really unpleasant feeling. That's what I couldn't sit with and I couldn't cope with that feeling, so I went back to drinking.

Tb4 has other effects that are needed in healing and repair of damaged tissue. It is a chemo-attractant for cells, stimulates new blood vessel growth (angiogenesis), downregulates cytokines and reduces inflammation, thus protecting newly formed tissue from damaging inflammatory events. Tb4 has been shown to reduce free radical levels (with similar efficiency as superoxide dismutase), decrease lipid peroxidation, inhibit interleukin 1 and other cytokines, and decrease inflammatory thromboxane (TxB2) and prostaglandin (PGF2 alpha).
Injection is the most effective way to administrate the peptide and results are seen the fastest and best. The nasal spray method is effective up to 30 – 40% because the nasal passages have poor absorption rate, you have to apply the nasal spray at least two to three times more than the injection. The injectable product of the Melanotan is very superior as compared to the nasal version. The nasal versions generally take four to five weeks for displaying the results appose to 10 days with the injection.
Supplementation of 5-HTP has been shown to be more effective than tryptophan supplementation alone. This additional benefit of 5-HTP supplementation arises because 5-HTP bypasses the cell's L-tryptophan's own self-regulation on the IDO enzyme, in which it upregulates the activity of IDO (discussed in next section) to maintain body homeostasis of tryptophan[6] and it bypasses the tryptophan hydroxylase enzyme, which is the rate limiting step in serotonin biosynthesis.[7]
My mother was a mother of 6 born between 1948 and 1961. She was a great advocate for lots of cuddles and physical contact with all of her children (as was my dad). This included baby massage directly on the skin as she emphasised touch as being very important. She passed this knowledge onto me when I became an aunt and then a mother. I am very grateful to have had such a hands on, affectionate and intuitive mother as a role model.
To further determine the potential anti-inflammatory effects of Tβ4 activation, expressions of proinflammatory or osteoclastogenic cytokines were measured by RT-PCR (Fig 4A). The TNF-α, IL-1β, IL-6, IL-8, and IL-17 mRNA levels increased in the H2O2- stimulated PDLCs, and these increases were significantly decreased in a concentration-dependent manner by treatment with the Tβ4 peptide. Since receptor activator of NF-κB ligand (RANKL) and osteoprotegerin (OPG) are two important osteoclastogenic factors, we next explored the effects of Tβ4 peptide on RANKL and OPG expressions in PDLCs. Tβ4 peptide reduced H2O2-stimulated up-regulation of RANKL, with a reciprocal increase in OPG mRNA in a dose-dependent manner (Fig 4B).
Sexual activity has been found to stimulate the release of oxytocin, and it appears to have a role in erection and orgasm. The reason for this is not fully understood, but, in women, it may be that the increased uterine motility may help sperm to reach their destination. Some have proposed a correlation between the concentration of oxytocin and the intensity of orgasm.

Melanotan 2 works by stimulating the release of the pigment melanin from the skin. Less UV exposure is necessary with Melanotan 2 compared to “normal tanning”, and the tan that occurs with tanning injections is deeper and longer lasting than an individual’s “normal tan”. Melanotan works best (has the most noticeable effects) on people with fair skin tones.

It turns out the love hormone oxytocin is two-faced. Oxytocin has long been known as the warm, fuzzy hormone that promotes feelings of love, social bonding and well-being. It's even being tested as an anti-anxiety drug. But new Northwestern Medicine® research shows oxytocin also can cause emotional pain, an entirely new, darker identity for the hormone.
“I didn’t think it would be that bad honestly, but since I weight lift multiple times a weak, this supplement is doing me more harm than good. On a typical weight lifting day my workout is split into 5 sections. After taking 5-htp the night before I barely have enough energy to get through 1 section, and that is a serious problem, because of this I am quitting 5-htp all together.”
“Further analysis by gender revealed that females in the 5-HTP group had a significantly lower panic rate and intensity of cognitive symptoms whereas, in males, the effect of 5-HTP was limited to lowering the intensity of somatic panic symptoms. Thus, an increased availability of 5-HT may have a gender-dependent protective effect in CCK-4-induced panic.”

Oxytocin's story starts back in the early 1900s, when biochemists discovered that a substance from the posterior pituitary gland could promote labour contractions and lactation. When scientists later discovered the hormone responsible, they named it oxytocin after the Greek phrase meaning 'rapid birth'. Oxytocin is produced mainly by the brain's hypothalamus; in the 1970s, studies revealed that oxytocin-producing neurons send signals throughout the brain, suggesting that the hormone had a role in regulating behaviour.
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).
Unlike previous studies, the trial will include people with a wide range of symptoms — and one of its major aims is to uncover the set of factors that influence whether and how strongly people respond to oxytocin. Sikich will analyse many measures of cognition and social functioning, and collect blood samples to look for biomarkers — such as levels of oxytocin and the receptor it binds to — that are associated with a response. “Lin has really been trying to create conditions under which you could study the potential beneficial effects of oxytocin and really do this right,” says Carter.
A user knowing their skin type in relation to the Fitzpatrick scale is important because it will dictate dosing needs. It should be noted that those who will benefit the most from this product are those in the upper spectrum of the Fitzpatrick scale (Types 1, 2 and 3 especially). Skin type 1 and 2 users will typically take longer to see any results from this product, however once beautiful tan is obtained maintenance is easy.

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]
Despite these many roles, oxytocin is often reduced to a misleading label. While “hormone of love” may be great for catchy headlines and compelling marketing slogans, they are ultimately misleading. Jennifer Bartz from the Mount Sinai School of Medicine has found that oxytocin can have completely opposite effects on the way people behave, depending on how they view their relationships to other people.

Oxytocin is a powerful hormone that acts as a neurotransmitter in the brain. It regulates social interaction and sexual reproduction, playing a role in behaviors from maternal-infant bonding and milk release to empathy, generosity, and orgasm. When we hug or kiss a loved one, oxytocin levels increase; hence, oxytocin is often called "the love hormone." In fact, the hormone plays a huge role in all pair bonding. The hormone is greatly stimulated during sex, birth, and breastfeeding. Oxytocin is the hormone that underlies trust. It is also an antidote to depressive feelings.
In a 2-week long clinical trial involving 25 overweight diabetic subjects given no dietary restrictions, subjects who received 5-HTP had reduced caloric, carbohydrate, and fat intake compared to placebo. Subjects who received 5-HTP also have reduced body weight, blood sugar, insulin and HbA1C levels after 2 weeks, possibly due to changes in the diet (R).
Although obtaining Melanotan II and Bremelanotide is relatively easy to do, both substances come in powder form and then must be reconstituted using sterile water prior to subcutaneous injection—a method of administration that can cause lead to skin bruising, cross-contamination, or infection, if the person performing the injection is inexperienced and the syringe isn't clean.

Melanotan 2 works by stimulating the release of the pigment melanin from the skin.

Melanotan works best (has the most noticeable effects) on people with fair skin tones.
These results were in agreement with previous studies that showed Wnt5a expression can be induced in activated macrophages, endothelial cells, and bone marrow mesenchymal stem cells (BMSCs) after inflammatory stimulation [58, 59]. In addition, we found that the effects of Tβ4 peptide on H2O2-mediated induction of pro-inflammatory cytokines (NO, PGE2, TNF-α, IL-1β, IL-6, IL-8, and IL-17), the expression of inflammatory mediators (iNOS and COX-2), osteoclastogenic cytokines (cathepsin-K, calcitonin receptor or Calcr, NFATc1, and RANK), and osteoclastic differentiation, were reversed by exogenous treatment with Wnt5a siRNA but enhanced by rh-Wnt5a, suggesting that the anti-inflammatory and anti-osteoclastogenetic effects of Tβ4 activation were involved the Wnt5a-dependent signaling pathway. Similar to our results, Wnt5a knock-down markedly reduced cytokine/chemokine production induced by TNF in HDPCs [60].
