For decades, professional bodybuilders have sworn by genetics as the factor most responsible for success. Others, however, have rightly noted that performance-enhancing drugs have substantially contributed to professional physique development in the past decades.

Still, genetics are the overriding regulator of size, density, hardness and other muscular qualities, even if you use steroids and other performance-enhancing products, including supplements. In fact, you could say that there's been a shift in our understanding of the body. No longer are we in a simple macronutrient mode in which we simply feed the body a generalized diet or give it a single training method. We're now in the era of genetics.

This was recently confirmed by the development of new genetic-testing kits that have hit the market, promising individualized "genetic supplementation." Beware these! Although legitimate genetic testing is being done, nothing is yet available to consumers. The science simply isn't that developed yet.

Recent research at the University of Sydney confirms that many interacting genes are involved in athletic performance, ...
... and that the presence of one single gene isn't meaningful or predictive of present athletic performance or future performance expectations.

So here's your FUSION FACTOID: Your genetics are important, but they're not the only game in town. The bottom line, at least for now, is that the science isn't yet sufficiently developed to offer meaningful and reliable home scientific genetic tests. In other words, if you're thinking about getting a genetic test - especially if it's online or through the mail - don't. Save your money and buy some protein instead. Those genes will make good use of it!
