No jokeing grapefruits have an enzyme that get you shredded! they are one of the top 10 anabolic foods. Herring is #1. herring is the most anabolic food it packs a shitload of natural creatine! Grapefruits are underestimated. they are in the Top 10 as well so is yogurt,broccoli,spinach. If you eat alot of these foods they do really help you get shredded and add alot of natural strength.
