I broke my neck this year at C6-C7 facets. Started taking TB-500 immediately following the accident. I don’t sit still well and was back in the gym almost immediately, simply to not go stir crazy and pump the blood anyway I could. 8 weeks later I was hitting bodyweight overhead squats for reps with the jerk, 0 pain and completely stable spine. I’m in my late 30s. I eat well, sleep well, and drink a lot of water. I doubt I would have been as well off, had I not taken the TB.
The product can be of unknown quality and subject to contamination and stability concerns with use of multi-dose vials. There is no experience with the product other than through unregulated channels. There are health risks from the substance itself and its route of administration – documented in medical literature, case reports as well as reports from NSW PIC.
She recruited 31 men* and asked them to sniff either an oxytocin nasal spray or another spray with the same ingredients minus oxytocin – a placebo. A few weeks later, the sprays were swapped so that the men who took oxytocin now took the placebo, and vice versa. At the time, neither the scientists nor the volunteers knew which was which – that was only revealed after the experiment was over.
Melanotan II is a synthetic analogue of the α-melanocyte stimulating hormone (α-MSH). α-MSH is a melanocortin I receptor agonist which has a role in human pigmentation by stimulating production of eumelanin. As melanotan II is a non-specific melanocortin receptor agonist, it has been reported to cause toxicity effects involving the many physiological systems affected by the receptors.
Both the production of oxytocin and response to oxytocin are modulated by circulating levels of sex steroids. The burst of oxytocin released at birth seems to be triggered in part by cervical and vaginal stimulation by the fetus, but also because of abruptly declining concentrations of progesterone. Another well-studied effect of steroid hormones is the marked increase in synthesis of uterine (myometrial) oxytocin receptors late in gestation, resulting from increasing concentrations of circulating estrogen.

5-HTP can affect a brain chemical called serotonin. Dextromethorphan (Robitussin DM, others) can also affect serotonin. Taking 5-HTP along with dextromethorphan (Robitussin DM, others) might cause too much serotonin in the brain and can result in serious side effects including heart problems, shivering, and anxiety. Do not take 5-HTP if you are taking dextromethorphan (Robitussin DM, and others).
Stimulation of milk ejection (milk letdown): Milk is initially secreted into small sacs within the mammary gland called alveoli, from which it must be ejected for consumption or harvesting. Mammary alveoli are surrounded by smooth muscle (myoepithelial) cells which are a prominant target cell for oxytocin. Oxytocin stimulates contraction of myoepithelial cells, causing milk to be ejected into the ducts and cisterns.
Neurovascular units within the central nervous system consist of endothelial cells, pericytes, neurons and glial cells, as well as growth factors and extracellular matrix proteins that are close to the endothelium.72,73 Neurovascular units provide niches for neural stem/progenitor cells in the adult brain and, within these units, newly-generated immature neurons are closely associated with the remodeling vasculature. The generation of new vasculature facilitates several coupled neurorestorative processes including neurogenesis and synaptogenesis, which improve functional recovery.74-76 The vascular production of stromal-derived factor 1 and angiopoietin 1 is involved in neurogenesis and promotes behavioral recovery after stroke.77 The disruption of this neurovascular coordination has been observed in a variety of brain conditions including infection, stroke and trauma.78 The injured brain promotes angiogenesis and neurogenesis,13,32,69,79-84 that may contribute to spontaneous functional recovery from injuries such as stroke and TBI. Neurorestorative agents that increase angiogenesis and neurogenesis have been shown to improve functional outcome following brain injury.19,33 Vascular endothelial cells within the neurovascular niche affect neurogenesis directly via contact with neural progenitor cells, while soluble factors from the vascular system that are released into the CNS enhance neurogenesis via paracrine signaling.85 Here, we demonstrate that Tβ4 treatment promotes both angiogenesis and neurogenesis in rats after TBI, suggesting that the neurovascular remodeling at least partially contributes to Tβ4-mediated improvement in functional recovery. A better understanding of molecular mechanisms in the neurovascular niches will be important for developing novel angiogenic and neurogenic therapies for brain injuries.

Oral 5-HTP results in an increase in urinary 5-HIAA, a serotonin metabolite, indicating that 5-HTP is peripherally metabolized to serotonin, which is then metabolized. This might cause a false positive test in tests looking for carcinoid syndrome.[28][29] Due to the conversion of 5-HTP into serotonin by the liver, there could be a risk of heart valve disease from serotonin's effect on the heart, as based on preclinical findings.[30][31] However, 5-HTP has not been associated with cardiac toxicity in humans.[22][32][33][34]
