As a bulking agent, the effects of Masteron will prove to be rather weak. It is possible the hormone could provide gains in mass similar to Primobolan (which wouldn't be that strong either) if the total dose was sufficiently high. However, the relative gain in size will be moderate with many anabolic steroids being far more suited for this period of steroidal supplementation. Masteron does not aromatize and is not estrogenic; in fact, it shows anti-estrogenic traits in the body and binds to aromatase instead of other substrates. This is why it has been effective in the treatment of breast cancer.
The second most common usage of GW501516 and any other GW substance is the fact that it can help you to burn fat. Even though it does help you to burn fat, you will still find that it is non-catabolic and this means that you can still keep hold of your muscle mass. This is especially the case when you run it alongside Ostarine and S4 and you really only need to take 10-20mg every day in order to start seeing some serious results. When you run any GW substance, such as GW501516, you should do it in 8 week cycles as with any other steroid supplement. You will need to make sure that you cycle it properly if you want to see the biggest and best results however, because this will help you to avoid any side effects as well as showing you how you can learn the effects on your own body.
