BACKGROUND AND OBJECTIVES: Because of extensive first-pass metabolism, oral bioavailability of sildenafil reaches only 40%. Formation of the primary metabolite, N -desmethylsildenafil, is mainly mediated by the cytochrome P450 enzyme CYP3A4. In this study we investigated the influence of grapefruit juice, containing inhibitors of intestinal CYP3A4, on the pharmacokinetics of sildenafil and N -desmethylsildenafil. METHODS: In a randomized crossover study, 24 healthy white male volunteers received single 50-mg doses of sildenafil. Two doses each of 250 ml grapefruit juice or water, respectively, were administered 1 hour before and together with the drug. Plasma concentrations of sildenafil and N -desmethylsildenafil were determined up to 24 hours post dose by use of liquid chromatography-tandem mass spectrometry (limit of quantification, 1 ng/ml). RESULTS: Grapefruit juice changed the area under the sildenafil plasma concentration-time curve from time zero to infinity [AUC(0-infinity) from 620 [1.53] ng/ml x h to 761 [1.58] ng/ml x h (geometric mean with geometric standard deviation), corresponding to a 23% increase (90% confidence interval, 13%-33%). N-Desmethyl sildenafil AUC(0-infinity) increased by 24% (90% confidence interval, 17%-32%). Maximum plasma concentrations (C(max)) of sildenafil and N -desmethylsildenafil were essentially unchanged. There was a trend toward a prolonged time to reach C(max) during the grapefruit juice period (from a median of 0.75 hour to a median of 1.13 hours), corresponding to an increase by 0.25 hour (90% confidence interval, 0-0.63 hour). Interindividual variability was pronounced in both periods. CONCLUSIONS: Grapefruit juice increases sildenafil bioavailability and tends to delay sildenafil absorption. Sildenafil pharmacokinetics may become less predictable with grapefruit juice. Although patients usually will not be endangered by concomitant use of grapefruit juice, it seems advisable to avoid this combination.

Hey AN guys - What is the caffeine dose like in this? I typically workout in the afternoon, and wondered when is the latest it should be taken?
Or on the other hand, are there any plans for a non-stim version?

But, I assure you it is not a wing... because I just spent another $259 on a round-trip tix to Venice CA to see the real big boys at Max Muscle. JJ Cutty brother!
I just turned 22 five months ago... I'm 206 @ 5%, and 5'10''.
Jay Cutty: 33 years old... 267 @ 2% BF, and 5'10''.
YES... THOSE NUMBERS KEEP MY HEAD ON STRAIGHT HUMBLE!
