The studies I looked at noted that continuous, daily doses of caffeine inhibited creatine uptake completely. On the flip side, taking caffeine less frequently - and more importantly -
timed before an intermittent sprinting session, helped performance significantly. The effect was described as ergogenic so that should transfer over to strength conditioning quite well.
Effect of caffeine ingestion after creatine supplementation on intermittent high-intensity sprint performance
Note that during the six days of creatine loading, no caffeine was administered at all. Likely because of the previous study that showed continuous caffeine intake was a no-go.
So how does that effect you, AlienShogun? For all I know, maybe not a damn bit. It makes sense though considering how the body builds a tolerance to continued caffeine intake that it would pack more of a punch when taken strategically - and much less frequently. You're probably getting to a fitness level where supplementation considerations make a larger relative impact, too, unlike the noob or intermediate who just needs to eat and work out to see progress.
