I'm going to run JW + Restore soon. I've run Powerfull and Cissus together. I definitely liked the joint relief I got, saw some strength increases, and felt an atypically confident attitude on the stack. But each time I've found that PF's effects tend to wane after around 20 days, so it's best used for when you need a relatively brief boost, rather than a 1-2 month type of cycle.
Based on everything I've read about JW + Restore, or even NHA, for example, it seems like people end up recomping to varying extents, even without aiming for that goal. The body composition effects and longer cycle length are big pluses for me.
