Does any of this mean just taking drugs will make someone a stage ready bodybuilder? Of course not and I never said that they would even if that’s what the guy heard. Our hypothetical guy at least need some fat burners to get lean. Throw in some clen, thyroid and GH (or go nuts with DNP) and you can get ripped without having to even diet too hard. That won’t make up for poor muscle bellies, symmetry and all of that but you get my point. A guy with 600 mg/week of anabolics and some basic fat burners will outgain and out lean a guy busting his ass in the weight room and watching his diet.
As a free-form supplement, leucine gets absorbed into circulation much faster than when it's part of a whole protein. Even with a fast-digesting protein such as whey, it can take hours for the leucine to be liberated from the protein and enter circulation. Therefore, leucine concentrations in the blood never spike to high levels. An isolated leucine supplement, however, would be quickly absorbed into circulation, thus spiking blood leucine levels and drastically increasing intracellular leucine concentrations and activating anabolic pathways.
