A good cutting stack with SARMs would be Cardarine GW-501516 (12,5 mgs ED), Andarine S4 (50 mgs per day) and Nutrobal MK-677 (25 mgs per day). As for the abs, just like mentioned above, 8-9% will already make the abs visible. However, much will depend on the training you give to your abs, and how varied it is. Also, keep your diet on point, even when using these SARMs for fat loss.
