Just dont be dissapointed with the test bro. Nothing brings gains on like dbol and drol, NOTHING! But without the test most peeps end up loosing just about everything they gain. Now that is not everybody so dont get bent out of shape. You are eating to build and you are gonna do the test too. So you will keep a lot of it IMO. Will interesting to see how much.

You're getting off track here bro lol. You should stick with the program, the squats are the most beneficial excersize there is period, its the foundation of this workout and will make all your lifts jump through the roof. If its hurting your lower back your doin something wrong. Probably leaning forward to much. If anything they should be strengthening your lower back, why dont you record a set and throw it up here so we can see what you're doing wrong
