Yeah, I grabbed a bottle of Cissus RX around when it first hit the market because I had pulled or torn a muscle in my shoulder (can't remember what the doc said it was) and started to get severe tendonitis in my right elbow from over compensating for the shoulder. I used up the bottle on max dosage, and what do you know, by the time I was done with it, the pain and stiffness and loss of mobility was almost back to pre-injury status, AND that was with lifting (lighter, more reps and TUT) the whole time. I don't think I let up on it the whole time, though I'd have to check my notebook from the time to be sure. I added some rotator cuff strengthening movements as well. Anyway, long story short, I was all better for a while, did a cycle of emax over the summer and all was good, then got a diff company's cissus and used that in the fall (it was pretty harsh on my stomach, so I will only come back to USP if I need any more!) for a few weeks for some lingering upper body soreness from post cycle. So, I haven't been on Cissus since late September, I believe, and I haven't had any serious problems with my shoulder or elbow since then. The weights have increased steadily in small increments since then with no recurrence of the injuries, in fact, my left shoulder started to crap out on me while doing 1,4/SD in late November yet the right one has been going steady! Cissus RX is the real deal and when I have a steady income again I will definitely grab some bottles to keep around for 'emergencies'.
Oh, and like what Mr. Taylor above says, when you're off the regular aches and pains return. Both times I used Cissus I had a marked reduction in DOMS and such, but it was still there, though not really all that PAINFUL if you take my meaning. But again, the joints and tendons that I messed up on my right arm and shoulder seem to do better than my left arm now, and I've noticed that when I am doing heavy benches my right arm is taking more of the weight than my left! Go figure, I am right-handed, but still, around March of last year I couldn't even do bench because my right arm was just trashed.
