Muscletech products work. Just not like they say they do. They take ingredients that are well known to have a positive effect on building muscle/burning fat (depends on which product we are talking about) and over hype them, give them fancy names, and create ridiculous ads that make their products appear to be the best thing since sliced bread, and then they go on to charge you out the a$$ for something you could get for a fraction of the price if bought elsewhere. Like said before, Leukic is essentially just the amino acid Leucine, except with a fancy name. Your best bet is to avoid Muscletech products unless you have a fetish for blowing money. Head over to nutraplanet.com and look under the bulk powders section and look at buying some bulk Leucine, its the same thing, except for the fancy name and ridiculous advertising.
