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.
In some cases, bodybuilders and athletes may choose to use Winstrol for a short time without using any other compounds. This can increase the risk of some side effects while decreasing the risk of others. For example, failing to use testosterone alongside your Winstrol may lead to some unwanted side effects associated with low testosterone, such as fatigue or a lowered libido. However, if you choose to forego testosterone, there’s no need to add an AI to your stack, which can make things simpler and save you money. You should be sure to weigh the benefits of using a Winstrol cycle with stacks and the risks of running a Winstrol-only cycle before you make a decision.
