The sequence LKKTET, which starts at residue 17 of the 43-aminoacid sequence of thymosin beta-4, and is strongly conserved between all β-thymosins, together with a similar sequence in WH2 domains, is frequently referred to as "the actin-binding motif" of these proteins, although modelling based on X-ray crystallography has shown that essentially the entire length of the β-thymosin sequence interacts with actin in the actin-thymosin complex.[13]
Feeding: a 2012 paper suggested that oxytocin neurons in the para-ventricular hypothalamus in the brain may play a key role in suppressing appetite under normal conditions and that other hypothalamic neurons may trigger eating via inhibition of these oxytocin neurons. This population of oxytocin neurons are absent in Prader-Willi syndrome, a genetic disorder that leads to uncontrollable feeding and obesity, and may play a key role in its pathophysiology.[54]
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…
Depression. Some clinical research shows that taking 5-HTP by mouth improve symptoms of depression in some people. Some clinical research shows that taking 5-HTP by mouth might be as beneficial as certain prescription antidepressant drugs for improving depression symptoms. In most studies, 150-800 mg daily of 5-HTP was taken. In some cases, higher doses have been used.

Evidence accumulated over the past decades has overturned the traditional dogma that the adult mammalian brain cannot generate new neurons. Adult neurogenesis has been identified in all vertebrate species examined thus far including humans.44-49 Newly generated neuronal cells originate from neural stem cells in the adult brain. Neural stem cells are the self-renewing, multipotent cells that generate the neuronal and glial cells of the nervous system.50 The major function of neurogenesis in adult brain seems to replace the neurons that die regularly in certain brain areas. Granule neurons in the DG continuously die and the progenitors in the subgranular zone of the DG may proliferate at the same rate as mature neuronal death to maintain a constant DG cell number.51 Similarly, the newly proliferated cells from the subventricular zone migrate and replenish the dead olfactory bulb neurons.52 Here, we focus on DG neurogenesis which is important for spatial learning and memory. In normal adult rats, newborn neural cells migrate from the subgranular zone of the DG of the hippocampus into the granule cell layer and eventually become mature granule neurons.53 These new granule neurons extend axonal processes to their postsynaptic targets54-57 and receive synaptic input.58 TBI stimulates widespread cellular proliferation in rats and results in focal neurogenesis in the DG of the hippocampus.59,60 Some of the newly generated granule neurons integrate into the hippocampus. The integration of the injury-induced neurogenic population into the existing hippocampal circuitry coincides with the time point when cognitive recovery is observed in injured animals.44
At least one study using an extract of Griffonia simplicifolia (10.24mg giving 2.56mg 5-HTP; confounded with Centella asiatica and Taraxacum officinale at 11.7mg and 4.55mg Paulina cupana and 9.75mg Artichoke extract) taken in three hits, five times a day (40mg 5-HTP total), by 20 overweight or obese females (non-depressive and without eating disorders) for 4 weeks has noted an increase in satiety and reduced binge eating tendencies; the increase in satiety was said to account for the improved weight loss results seen in the experimental group when both were given weight loss advice and diets.[3] This spray has been noted elsewhere to increase satiety (and vicariously through that, body weight) over 2 months in a similar demographic of women.[2]
Injected oxytocin analogues are used to induce labour and support labour in case of non-progression of parturition. It has largely replaced ergotamine as the principal agent to increase uterine tone in acute postpartum haemorrhage. Oxytocin is also used in veterinary medicine to facilitate birth and to increase milk production. The tocolytic agent atosiban (Tractocile®) acts as an antagonist of oxytocin receptors; this drug is registered in many countries to suppress premature labour between 24 and 33 weeks of gestation. It has fewer side-effects than drugs previously used for this purpose (ritodrine, salbutamol and terbutaline).
Can a supplement proven to fight blue moods also help stimulate weight loss? “Yes it can!” say experts who are now prescribing a natural compound called 5-HTP. According to top integrative health expert Tasneem Bhatia, MD, author of What Doctors Eat ($15.99, Amazon), “5-HTP is converted directly to serotonin, and serotonin makes you feel good, feel happy, feel full — and when you feel that way, you’re going to eat less.” In fact, Dr. Bhatia adds that while most appetite suppressants only target physical hunger, this one also “works to reduce ‘emotional hunger’ and stress-related urges to eat.” Dr. Oz said he left impressed after consulting with a panel of 5-HTP experts, including American Board of Obesity Medicine alum Denise E. Bruner, MD. He said the supplements may even be “a secret weapon for hunger!”
All of this becomes heavily ironic when you consider that the chemical in question – a hormone called oxytocin – is often billed as the “hormone of love”, and even marketed as “Liquid Trust”. As a new study shows, the reality is much more complicated. Describing oxytocin as the “hormone of love” is like describing a computer as a “writing tool” – it does other things too, some of which aren’t pleasant.

Eventually I found Dr Kristaps Paddock, a naturopathic doctor and 5-HTP expert from Maryland in the US. He said one benefit 5-HTP has over SSRIs is that it kicks in quickly for those with anxiety and depression. "Serotonin has a short metabolic half-life, so it metabolises very, very fast. It goes into the body and out at a great speed, unlike SSRIs, which take a while to take effect so a sufferer wouldn't be feeling good during that time, and in fact may be feeling more suicidal. SSRIs also then have to be weaned off slowly, whereas you can stop taking 5-HTP instantly." Another bonus, of course, is that it's natural rather than synthetic. "If you're seriously considering the supplement, you have to weigh the positives and negatives against each other. The toxicity with 5-HTP is lower than that of SSRIs, since it's natural. Also because it's metabolised much quicker, it'd get out of your system more quickly if there were any problems. On the other hand, the research basis for 5-HTP is dramatically lower, so it's important to think of that."

I found this to be an excellent supplement for myself, which overcomes the rate limiting step when the body converts tryptophan to 5-HTP. I am sleeping much better and handling life's normal stresses better. If you haven't already, become familiar with how/why the body converts L-Tryptophan > 5-HTP > Serotonin > Melatonin. Very interesting! Thank you Bulk Nutrients for making this available.
Drug interaction: Impact on effects of alcohol and other drugs: According to several studies in animals, oxytocin inhibits the development of tolerance to various addictive drugs (opiates, cocaine, alcohol), and reduces withdrawal symptoms.[68] MDMA (ecstasy) may increase feelings of love, empathy, and connection to others by stimulating oxytocin activity primarily via activation of serotonin 5-HT1A receptors, if initial studies in animals apply to humans.[69] The anxiolytic Buspar (buspirone) may produce some of its effects via 5-HT1A receptor-induced oxytocin stimulation as well.[70][71]

Thymosin Beta 4 is a potent peptide that comes from a family of 16 related molecules that are localized in circulating cells and tissues within the body. These molecules also have a high conservation of sequence. TB 500 conjoins with actin and prevents actin polymerization. It is noted as being the actin-sequestering molecule within eukaryotic cells. It also boosts extracellular matrix-degrading enzyme production.
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.

5-HTP works in the brain and central nervous system by increasing the production of the chemical serotonin. Serotonin can affect sleep, appetite, temperature, sexual behavior, and pain sensation. Since 5-HTP increases the synthesis of serotonin, it is used for several diseases where serotonin is believed to play an important role including depression, insomnia, obesity, and many other conditions.
