you might be expecting too much out of a SARM here
sarm's are mild and will add very lean muscle mass slowly.. PPAR like GW will increase endurance and burn some fat. but they aren't going to turn you into a super hero sorry
s4 is definitely the best option when it comes to adding strength, followed by lgd... mk2866 is also great for strength... mind you they are not gong to provide steroid type strength but definitely will provide noticeable increases...
