To prevent adverse effects, always consult your physician and pharmacist before taking any drug or supplement. Inform your doctor and pharmacist about all drugs you take, whether they are prescription, non-prescription, vitamins, supplements, or herbs. Be sure to read and understand the Drug Facts section of the product label before taking any medication, and never take more than what is specified by your doctor. Dietary supplements are drugs, so be sure to keep them out of sight and reach of children and pets.
If the two things you can't live without are a dark, even tan and a fast-acting, long-lasting erection, then add Melanotan II to your holiday shopping list. This synthetic peptide hormone, which was developed by a research team at the University of Arizona during the late 1990s, darkens skin pigment and may stimulate erectile activity. And despite continued concern and controversy within the medical community regarding its use, it remains available for sale over the internet in a powdered form that can then be reconstituted for subcutaneous injections.
The group had first identified the thymosin sulfoxide as an active factor in culture fluid of cells responding to treatment with a steroid hormone, suggesting that its formation might form part of the mechanism by which steroids exert anti-inflammatory effects. Extracellular thymosin β4 would be readily oxidised to the sulfoxide in vivo at sites of inflammation, by the respiratory burst.
Astrocytes constitute the largest population of cells in the central nervous system, constituting approximately 90% of human parenchymal cells. Astrocytes are highly responsive to injury, undergoing rapid hyperplasia and hypertrophy. Astrocytes act as physical and biochemical barriers to axonal regeneration by forming glial scars along ischemic lesions and producing axonal growth-inhibitory proteoglycans. Administration of MSCs significantly attenuates the glial scar in the ischemic boundary and reduces expression of inhibitory proteins, such as Nogo. Analysis of single-cell astrocytes isolated from the ischemic boundary by laser capture microdissection reveals that administration of MSCs dramatically down regulates neurocan, an axonal growth-inhibitory proteoglycan. Coculture of MSCs with astrocytes also substantially reduces neurocan expression in astrocytes activated by oxygen glucose deprivation. These findings suggest that injected MSCs reduce physical and biochemical barriers of astrocytes, which also contribute to axonal and neurite outgrowth.
Hypoxic heart disease is a predominant cause of disability and death worldwide. As adult mammals are incapable of cardiac repair after infarction, the discovery of effective methods to achieve myocardial and vascular regeneration is crucial. Efforts to use stem cells to repopulate damaged tissue are currently limited by technical considerations and restricted cell potential. We discovered that the small, secreted peptide thymosin beta4 (Tbeta4) could be sufficiently used to inhibit myocardial cell death, stimulate vessel growth, and activate endogenous cardiac progenitors by reminding the adult heart on its embryonic program in vivo. The initiation of epicardial thickening accompanied by increase of myocardial and epicardial progenitors with or without infarction indicate that the reactivation process is independent of injury. Our results demonstrate Tbeta4 to be the first known molecule able to initiate simultaneous myocardial and vascular regeneration after systemic administration in vivo. Given our findings, the utility of Tbeta4 to heal cardiac injury may hold promise and warrant further investigation.
Established immortalized human PDLCs  that maintain the characteristics of primary PDLCs by transfecting human telomerase reverse transcriptase (hTERT) were used. These cell line were kindly provided by Professor Takashi Takata (Hiroshima University, Japan). Cells were cultured in α-MEM supplemented with 10% FBS, 100 U/mL penicillin, and 100 μg/mL streptomycin in a humidified atmosphere of 5% CO2 at 37°C. For the experiments, the cells were seeded into culture dishes and then cultured in α-MEM containing 10% FBS for 2 days until 70% confluent, and, then, the media was replaced by serum-free medium in order to minimize any serum-induced effects on PDLCs. Subsequently, the cells were exposed to H2O2 and human Tβ4 peptide (RegeneRx Biopharmaceuticals Inc., Rockville, MD). All treatments were performed in triplicate and approved by the local ethics committee.
5-HTP has been shown in scientific studies to promote relaxation and alleviate stress and anxiety. The relaxation and anti-anxiety properties of 5-HTP appear to come from its ability to elevate levels of serotonin. Research has demonstrated that 5-HTP may reduce the risks of panic attacks and symptoms of panic, as well as anxiety and emotional stress. Research also indicates 5-HTP may be effective in helping to alleviate depression.
In some studies that record appetite suppression with 5-HTP supplementation, nausea appears to also be reported at higher freqencies than placebo, although some interventions note this as the only relevant side effect. Short term studies tend to note that nausea persists throughout the study period while those expanding beyond three weeks note that reports of nausea tend to decline at this time point.
Don't be surprised. A lot of people haven't heard of Melanotan. Melanotan is a tanning peptide that stimulates the production of melanin in the body to foster a deep, natural tan. This is the body's way of protecting itself from too much sun exposure by increasing the level of melanin in the body. Melanin is your body's natural response to UV damage. The end result is a darkening of the skin.
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).
While the structure of oxytocin is highly conserved in placental mammals, a novel structure of oxytocin was recently reported in marmosets, tamarins, and other new world primates. Genomic sequencing of the gene for oxytocin revealed a single in-frame mutation (thymine for cytosine) which results in a single amino acid substitution at the 8-position (proline for leucine). Since this original Lee et al. paper, two other laboratories have confirmed Pro8-OT and documented additional oxytocin structural variants in this primate taxon. Vargas-Pinilla et al. sequenced the coding regions of the OXT gene in other genera in new world primates and identified the following variants in addition to Leu8- and Pro8-OT: Ala8-OT, Thr8-OT, and Val3/Pro8-OT. Ren et al. identified a variant further, Phe2-OT in howler monkeys.
Exogenous Tβ4 can function like a hormone on cells in terms of its ability to modulate their biological behavior. Since one of the primary roles of Tβ4 in cells is the sequestration of actin monomers, and the protein is not secreted, previously indicated that it was unlikely that Tβ4 could have a hormonal function . However, other studies have shown that the intracellular level of Tβ4 or its mRNA can be significantly and rapidly altered by external stimuli and that change in the level of Tβ4 often are correlated with cell differentiation [18, 43]. In the present study, exogenous Tβ4 peptide activate intracellular Tβ4, which results suggested that exogenous Tβ4 spontaneously enter the cytoplasm through rapid internalization, and acts their functions same as endogenous one [8, 18].
5-HTP increases a brain chemical called serotonin. Some medications for depression also increase serotonin. Taking 5-HTP along with these medications for depression might increase serotonin too much and cause serious side effects including heart problems, shivering, and anxiety. Do not take 5-HTP if you are taking medications for depression.
Some of these medications for depression include fluoxetine (Prozac), paroxetine (Paxil), sertraline (Zoloft), amitriptyline (Elavil), clomipramine (Anafranil), imipramine (Tofranil), and others.
But this isn’t the only study to show the subtle side of oxytocin. Just three months ago, I wrote about research from Heejung Kim at the University of California, which showed how oxytocin’s effects vary across different cultures. To fulfil its many roles, oxytocin has to dock at a protein called the ‘oxytocin receptor’, encoded by a gene called OXTR.

I’ve been on this stuff for lots of years. I really needed it when I was depressed like hell, and I had an emotional pain that simply didn’t go away for 2 decades prior to starting that stack. Did it help? yes. Was it the best intervention possible? probably not. I was able to get off all this stuff with the uridine stack, and I believe it partly fixed a part of my brain that was damaged from this decade long suffering. So this is, why I am now more into brain regeneration and psychotherapeutic interventions (even though I do them myself), and I would only go back to this stack if I was completely fucked up again. There are a lot of side effects, and its a fine line to balance the supplements, to get rid of the side effects…
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.
Hi Ben, I have been using TB-500 for minor injury repair assistance for more than 2 years. I have found it to be extremely effective for minor strains to calves, hamstring, shoulder etc. Luckily I have not had to try it for any major injuries. When I first used it I was blown away by how effectively it worked – even to the point that I began to doubt the seriousness of the original injury. When injured I dose at 5mg per week for four weeks then take at least four weeks break. The only side affect I have noticed is a little light headed feeling which passes pretty quickly. I am in my late 40’s and I train hard. TB-500 allows me to train through minor injuries which is great. Love your work
Do I have to diet? Studies show that 5-HTP enhances weight loss even if you continue eating your normal foods. Without a diet, you stand to lose about a pound a week; many folks eventually drop 15 pounds or more without dieting. Of course, taking 5-HTP to lose weight works by lowering caloric intake — and the more calories you cut, the more you’ll lose. So if you want to maximize results, try tweaking your diet at the two-week mark, when 5-HTP will have fully kicked in, diminishing hunger and carb cravings. Below, we’ve got a version of the diet used in one university study that helped 5-HTP takers lose several times more weight than folks getting a placebo.
Kim found that when Americans who carry a particular version of the OXTR gene are more likely to turn to their friends for support when they are distressed. But Koreans react to social stress in a different way – for them, it’s less socially acceptable to turn to friends for support during tough times. And distressed Koreans who carry the same version of OXTR are less likely to seek support from their friends.
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."
