TB-500 is a peptide fragment hormone that is primarily used in the treatment of various muscle injuries or pain caused by inflammation. There is very little official human data available for this product; however, it has been a longtime hormone used in racehorses. TB-500, although synthetic, serves to act as a synthetic form (loosely) of Thymosin Beta-4 (TB-4). TB-500 is not TB-4; although very commonly confused as TB-4, it is designed to provide the benefits of the naturally occurring thymus produced hormone.
The thymus gland as well as in various localized cells in the human body produces thymosin Beta-4 (TB-4). TB-4 is found in cytoplasm in high levels of concentration as well as in wound fluid. TB 500 is designed to promote the actionable area – the part of TB-4 that promotes healing. More importantly, manufacturing TB-500, despite not being TB-4 is possible while the latter is extremely difficult. The primary purpose of Thymosin Beta 4 lies in its ability to promote the upregulation of cells in the body. Upregulation increases the cell’s sensitivity to action, specifically in proteins such as actin. This action helps to regulate inflammation in injured areas of the body as well as provide new blood vessel pathways. Of interesting note – TB-500 possesses a very low molecular weight allowing it to carry a high level of mobility in the body. Simply put, Thymosin Beta 4 can travel long distances through the body, virtually to all locations. TB-500 does not have to be administered to the injured area but will find its way to all injured areas regardless of administrated location.
In the world of performance enhancement, TB-500 is not meant to be used to bulk, cut, lose fat or increase strength. This is a peptide hormone that is designed to promote healing, specifically the healing of wounded or injured areas of the body. TB-500 can be used to treat muscle tears or strain, tendon inflammation and even skin injuries. This peptide will not cause instant healing of an injured area. If a muscle is torn it is torn, but use of TB-500 will in many cases speed up the healing process. For nagging injuries, those that don’t keep the individual out of the gym but slow his progress, it may provide the edge he needs to continue his training without it being diminished. The effects of TB-500 have also been linked to hair growth, specifically the reversal of hair loss caused by male-pattern baldness. However, how significant this effect is and how much truth it holds scientifically is still highly questionable as no official data exist. The only data on hair growth is anecdotal.
