Grapefruit is thought to aid in absorption of certain orals through inhibiting the action of enzymes, mainly CYP 450 I think, that break down the streoid in your body before it is fully utilized. Grapefruit messes with certain perscriptions alot, especially heart and blood pressure medication. When it comes to methylated drugs (dbol, anadrol, winny, etc.) grapefruit will have little if any effect. The methylation is enough to ensure adequate absorption. Prohormones often included or were taken with DHB, which is a grapefruit extract to enhace the absorption of non-methylated orals. Bottom line, grapefruit will have little to no impact with gear.
