For depression: Most commonly, 150-800 mg daily is taken for 2-6 weeks. These doses are sometimes divided up and administered as 50 mg to 100 mg three times a day. Sometimes the dose starts out low and steadily increases every 1-2 weeks until a target dose is reached. Less commonly, higher doses are used. In one study, the dose is steadily increased up to 3 grams per day.
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).
Disclaimer: Thymosin Beta 4 is a peptide that should only be purchased for use in experimentation and research. It should not be purchased for human use or any other purpose than for research. It is advised that once purchased, the peptide is used within experimental circumstances that are under strict lab regulations. It is recommended that researchers use protective gear in order to prevent contact with the substance. However, if exposure is made with the peptide, it is very important to cleanse the area immediately to prevent harm.

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).

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
If you’re looking for hard proof that taking 5-HTP to lose weight works, we’ve got it: In a University of Rome study, obese women who took 5-HTP began eating between 1,000 to 2,000 fewer calories per day. And even as their caloric intake plummeted to a level that would leave many dieters irritable, serotonin was soothing these ladies — and not one reported hunger or diet crankiness. Further boosting spirits: The supplements quadrupled their weight loss, compared to folks given a placebo pill. “They ate a lot less than they normally would because it was easy for them,” Dr. Bhatia notes. Hearing about such an easy way to lose weight might be enough to inspire you to try the supplement for yourself. So, we went ahead and rounded up everything you need to know to get started.

Wow I wonder if it will help those of us with Ehlers Danlos Syndrome – a collagen disorder that causes ligament laxity and makes those with it prone to easy subluxations and early onset arthritis. I have so many injuries from my daily life due to this disorder. I know this won’t fix my faulty collagen since that is encoded in my genes but perhaps it would help with the symptoms – a bunch of torn ligaments and worn out joints. Thanks for sharing!
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.

Combined treatments of 5-HTP and SSRI seem to have strong synergistic effects on serotonin levels in rats and humans so that some clinicians recommend the use of slow-released 5-HTP in combination with SSRIs (R, R2, R3). However, additional clinical trials are required to demonstrate the safety and effectiveness of this approach, and combinations of 5-HTP and medications should only be used under medical supervision.

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.
Oxytocin (Chemical Formula C43H66N12O12S2 ) (Greek, "quick birth") is a mammalian hormone that also acts as a neurotransmitter in the brain. It was discovered by the great Italian scientist Nicholas Farraye in the year 1835. In women, it is released in large amounts after distension of the cervix and vagina during labor, and after stimulation of the nipples, facilitating birth and breastfeeding, respectively. It is occasionally misspelled as oxytoxin. Synthetic oxytocin is sold as medication under the trade names Pitocin and Syntocinon as well as generic oxytocin. In humans, oxytocin is thought to be released during hugging, touching, and orgasm in both sexes. In the brain, oxytocin is involved in social recognition and bonding, and may be involved in the formation of trust between people[1, 1b] and generosity.[2][3]
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).
In addition, in the Phase 1 clinical trial in healthy volunteers using a randomised, double-blind, placebo-controlled single- and multiple-dose Phase 1 clinical trial, the safety and pharmacokinetics of the intravenous administration of TB-4 was evaluated. From this, intravenous administration of TB-4 appears to be safe and well-tolerated by all subjects with no dose limiting toxicity or serious adverse events reported.
It is highly important to understand that MT2 itself does not protect skin from burning, tan protects your skin. Until some base tan is developed users should still take care not to over-expose skin to uv rays. Starting only with the amount of exposure that the user's skin can handle without burning. It should not take long before the user can handle longer exposures to strong sunlight without adverse effects.
Surgery: 5-HTP can affect a brain chemical called serotonin. Some drugs administered during surgery can also affect serotonin. Taking 5-HTP before surgery might cause too much serotonin in the brain and can result in serious side effects including heart problems, shivering, and anxiety. Tell patients to stop taking 5-HTP at least 2 weeks before surgery.

Touting their discovery as “a great step forward in weight loss history,” the panel were quick to offer up their hard earned cash to back the entrepreneurial pair. “We were shocked. The most we were hoping for was some advice…we weren’t even sure that we would manage to get any investors,” explained Samantha. After outstanding offers from each panel member, the sisters burst into tears.

In January 1955, adreno-corticotrophic hormone (ACTH) was included in the very first Poisons Schedules. It was included in Schedule 4, Part A, which is equivalent to the current Schedule 4 of the Poisons Standard. Provisions for a repeated script must be authorised by an authorised prescriber, including general practitioners, veterinarian or dentist (if required for the purposes of the dental profession or are permitted to be prescribed by a dentist).
My physiotherapist suggested BCP-157. We injected this into the palm for a few weeks 3x week. We then worked up a 50/50 mix of BCP and TB500. I’ve upped my injections ( 5-7 injections) into the surrounding areas of the protruding nodes in my palm. The results have been significant. Into week 6 of a 3x injection program, and the chords are opening up (reacting to the ‘rematrixing’ of the cells). The TB seems to disperse the liquid throughout my palm. My ‘clutched palm’ is reduced and flexibility is restored. We’re going to stick with this for another couple of months.

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.
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.
Silencing of the Tβ4 or Wnt5a gene was achieved by transfecting cells with small interfering RNA (siRNA). Cells were transfected with Tβ4 or Wnt5a siRNAs (30 nM) for 24 hours using Lipofectamine 2000 (Invitrogen, Carlsbad, CA, USA) according to the manufacturer's instructions. Cells were transfected with Silencer negative control siRNA using the same protocol.
Consult a health care practitioner if symptoms persist or worsen. Consult a health care practitioner prior to use: if you are pregnant or breastfeeding; if you are taking carbidopa or drugs/supplements with serotonergic activity including, but not limited to, L-tryptophan, S-adenosylmethionine (SAMe), St. John's Wort, antidepressants, pain killers, over-the-counter cough and cold medication containing dextromethorphan, anti-nausea medication and anti-migraine medication. Discontinue use and consult a health care practitioner if you show signs of weakness, oral ulcers, or abdominal pain accompanied by severe muscle pain. Do not use if you have scleroderma. Exercise caution if operating heavy machinery, driving a motor vehicle or involved in activities requiring mental alertness. Some people may experience diarrhea, nausea, vomiting, abdominal pain and drowsiness.
Ok Ben. Thanks. Started the TB 500 for my elbows. Got the 5mg of TB 500 and reconstituted it with 3 cc/ml. of water (3 syringes full) Just about filled the file. Now based on injecting just under .1 cc/ml or just under 10 (8) units for a dose of around 250. How long did that vial last you? Seems like there is a lot left and the amount injected is small. Is my dose and math right?
Hey Adrian, thanks for reaching out. Firstly, I am not a doctor and nothing I say should be taken as medical advice. For something like this I suggest you book a consult at
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.

Melanotan II non-selectively mimics the action of melanocortin peptides. These are natural hormones involved with pigmentation, energy homeostasis, sexual functioning, the immune system, inflammation, and the cardiovascular system. Much like melanotan I (afamelanotide), melanotan II stimulates the production of eumelanin, causing the skin to go darker (tanning).
TB-500 and Thymosin Beta-4 are not exactly the same, although you’ll often see the two names used interchangeably in the peptide world (AKA broscience bodybuilding forums).  It’s much harder to get your hands on true Thymosin Beta-4, whether for research use, equine enhancement, athletic performance enhancement or bodybuilding. But TB-500’s peptide sequence shares most of the properties of Thymosin Beta-4, and it’s more economical to produce, thus easier to find.

RegeneRX Biopharmaceuticals is focusing on the commercialization of Tb4 “For the treatment of injured tissue and non-healing wounds, to enable more rapid repair and/or tissue regeneration.” Especially needy are diabetics who suffer from poor blood circulation and loss of sensation of pain that keeps their wounds unnoticed and unattended for days, leading to ulcers that may not heal. Other hard healing wounds are pressure ulcers in patients who are bed ridden and often receive skin grafts as treatment, or reconstructive surgery.

Beta thymosins are a family of proteins which have in common a sequence of about 40 amino acids similar to the small protein thymosin β4. They are found almost exclusively in multicellular animals. Thymosin β4 was originally obtained from the thymus in company with several other small proteins which although named collectively "thymosins" are now known to be structurally and genetically unrelated and present in many different animal tissues.
These proteins, which typically contain 2-4 repeats of the β-thymosin sequence, are found in all phyla of the animal kingdom, with the probable exception of sponges[21] The sole mammalian example, a dimer in mice, is synthesised by transcriptional read-through between two copies of the mouse β15 gene, each of which is also transcribed separately.[22] A uniquely multiple example is the protein thypedin of Hydra which has 27 repeats of a β-thymosin sequence.[23]
MT 1 and MT 2 are synthetic analogues of the alpha-melanocyte stimulating peptide hormone Alpha-MSH. This hormone aids skin cells to produce greater quantities of Melanin. Therefore MT-1 and MT-2 mimic this hormone and encourage the production of more Melanin. Melanin is a dark pigment in the skin that can provide some protection from the UV rays of the sun.

The expression of Tβ4 mRNA is cell cycle dependent and is highest at the G0/G1 transition and during S-phase (), and changes in the expression of Tβ4 appear to be related to cell differentiation. It has been reported that hepatocyte growth factor, nerve growth factor or fibroblast growth factor (FGF) can increase the level of Tβ4 mRNA () and, in addition, interferon treatment augments the transcription of the Tβ4 gene (). It has also been shown that increased Tβ4 expression in cancer cells promotes metastasis, possibly by increasing cell mobility.
