Not sure if you can get beast or sd anywhere but you can get helladrol at mrsupps.com and it will give you some of the same gains but not near as much as beast. But it wont have as many sides as beast on the other hand.
Helladrol is a great supp but im definitely looking for something on the stronger end like beast. I've run beast and it was awesome, lgi sd-15 gave the same results as well
Beastdrol or any other SD is now a class 3 controlled substance since it has been banned. I'm not saying you can't find it if you search hard enough, but it will be few and far between
