Here's some info on creatine. The part I'm interested in is "creatine in the muscle may also increase the rate of regeneration of phosphocreatine".
Creatine in the form of phosphocreatine (creatine phosphate) is an important store of energy in muscle cells. During intense exercise lasting around half a minute, phosphocreatine breaks down to creatine and phosphate, providing you with the primary source of energy, adenosine triphosphate (ATP). Output power drops as your cells deplete phosphocreatine, because the body cannot regenerate ATP fast enough to meet the demands of the exercise.
A bigger store of phosphocreatine in muscle reduces the depletion. Extra creatine in the muscle may also increase the rate of regeneration of phosphocreatine following repeated bursts of activity in training or in many sport competitions.
So, does Var help manufacture phosphocreatine? And if you add creatine to your Var cycle could it help the synthesis become more efficient (effective)?
