I actually know a bunch of guys that do regular cycles of gear that use Gakic off cycle. They claim if you know what you are doing, Gakic reduces muscle fatigue and does increase the amount of reps you do per set. This is a big deal for someone coming off a cycle because they will loose a good amount of mucle as they come off. Gakic helps build muscle endurance and helps you keep more mucsle and, more importantly, more muscle definition.
