One study appeared to show that gw 50156 side effects included the growth of cancer cells but on further inspection, the results could be considered misleading. The study of gw1516 which was carried out on mice included 1000 times the recommended dose, taken over a prolonged period of time. As no individual would be taking such an inflated level of gw501516, there is debatable value attached to this particular study. Nevertheless, despite the criticism of this study, it was sufficient for GSK to drop the project so shouldn’t be dismissed completely.
Lets assume all who read this are going to supplement with Trenbolone responsibly and if you do the odds of a positive experience are far more in your favor. However, because it is impossible to predict if you have never supplemented with this hormone before you are highly advised to stick only with the Acetate version, often referred to as Tren-a. Trenbolone-Acetate is by many the preferred Trenbolone hormone but for the first time user it is the only logical choice The reason is simple; if you fall prey to the sever side effects of Tren you can simply discontinue use and have the hormone cleared from your system in a little more than 48 hours. If you choose a larger ester based form such as Trenbolone- Enanthate and fall prey to sever Tren side effects its a different story; it will take weeks for the hormone to clear after discontinuation.
