IDS makes a product called "DHB Anabolic Amplifier" with a fair amount of DHB which is an active component in grapefruits that aid in absorption.
[Bergamottin (BG) and 6',7'-dihydroxybergamottin (DHB) are the most abundant furanocoumarins present in grapefruit juice and have been proposed as major intestinal CYP3A4 inhibitors contributing to grapefruit juice-drug interactions. The relative contribution of BG versus DHB to the interaction potential is unclear, in part due to inconsistencies in the literature regarding inhibitory potency.] - General Clinical Research Center (M.F.P., A.B.C., P.B.W.), Division of Pharmacotherapy (M.F.P., P.B.W.), and Department of Medicine (P.B.W.), University of North Carolina, Chapel Hill, North Carolina
Many have reported that it does seem to enhance the effects of anabolics and some report that it does nothing. I'd personally just go with Tropicana while taking ur pills effected by this enzyme!
