Which Jack3d Products do you use? How do you like them? I've seen them before but haven't tried them yet.
I use the regular Jack3d, not the Yok3d by USP Labs. They enabled me to push all of my weight training goals up through my plateau. My normal body weight was 155 (for 20 years) and now am at 225. Awesome for all forms of exercise (hence it's inclusion on most professional and collegiate sports banned substances lists), just more effective at weight training.
