I ran cissus with it, it was approved by William (the big boss) and is also part of a formula recently introduced by Universal.(Animal Test) And X Factor doesn't cause dry aching joints. It is released when damage occurs, ex: Muscle fibers. AA release is the important start of the process of recovery. If you don't lift too much weight (like most of us do, I do too sometimes), and you focus on mind muscle connection, you will have virtually no pain.
And Cellar, as long as DOMS are there, you can keep the cissus
(Otherwise, send it to me
)
