Eh, da un pò... anche io ero convinto che fosse una combinazione da evitare. Ma a quanto pare, escludendo quell'unico studio che dimostrava una diminuzione dell'effetto erogenico di creatina abbinata alla caffeina, nessuno sa con precisone se questa combinazione è deleteria.

Puoi trovare la caffeina insieme a svariate forme di creatina in qualche No2 booster.
Adesso mi viene in mente il NoExplode, ma ce ne sono sicuramente altri.

This study aimed to compare the effects of oral creatine (Cr) supplementation with creatine supplementation in combination with caffeine (Cr+C) on muscle phosphocreatine (PCr) level and performance in healthy male volunteers (n = 9). Before and after 6 days of placebo, Cr (0.5 g x kg-1 x day-1), or Cr (0.5 g x kg-1 x day-1) + C (5 mg x kg-1 x day-1) supplementation, 31P-nuclear magnetic resonance spectroscopy of the gastrocnemius muscle and a maximal intermittent exercise fatigue test of the knee extensors on an isokinetic dynamometer were performed. The exercise consisted of three consecutive maximal isometric contractions and three interval series of 90, 80, and 50 maximal voluntary contractions performed with a rest interval of 2 min between the series. Muscle ATP concentration remained constant over the three experimental conditions. Cr and Cr+C increased (P < 0.05) muscle PCr concentration by 4-6%. Dynamic torque production, however, was increased by 10-23% (P < 0.05) by Cr but was not changed by Cr+C. Torque improvement during Cr was most prominent immediately after the 2-min rest between the exercise bouts. The data show that Cr supplementation elevates muscle PCr concentration and markedly improves performance during intense intermittent exercise. This ergogenic effect, however, is completely eliminated by caffeine intake.

Certo è che la caffeina è acida e può intaccare la crea convertendola in creatinina. Meglio non rischiare secondo me.

Non vedo inoltre il motivo per inserire la caffeina in uno stimolatore dell'ossido nitrico
