Plasma creatinine, but not creatinine clearance, increased in the supplement group, but there were no changes in serum creatine kinase activity or liver function
Beta-hydroxy-beta-methylbutyrate, or HMB, is a downstream metabolite of the branched-chain amino acid leucine. Many studies have shown that leucine is … continue reading
The foundational ingredient of Hydroxycut Hardcore X has been shown to elevate resting metabolic rate and increase intensity levels, which, research suggests, provides the type of metabolic help that individuals need to burn through more calories.
The supplements chosen for the study have an impressive record of effectiveness for bodybuilding purposes.
Specifically, PEG is believed to enhance the gastrointestinal absorption of creatine by increasing permeability coefficients in the GI tract and across the sarcolemma.
Spirulina—you know, that gooey green stuff you see folks blending at natural food stores—may actually be good for you. Personally, … continue reading
Mention the word calcium, and just about everyone thinks about bones or teeth. It’s true that the majority of calcium is stored in bones, but the small amount that circulates in the blood—about 1 percent—is vital.

Taking the protein before and after training blocked the response of both active and total testosterone to the exercise, much the way that it happens in younger men
The supplements contain such compounds as arginine or glycine propionyl-L-carnitine, which help the body produce NO, which in turn dilates blood vessels.
