A drug almost all Yankee players use to become good at baseball. Once their bodies start to break down from these drugs the Yankees try to void their contracts. But they like to keep other players who admit they were on steroids because they're still producing.
Person #1: Jason Giambi took steroids and the Yankees want to void his contract.
Person #2: So did Gary Sheffield.
Person #1: But he's still good so we'll let it slide.

Get the steroids mug.
A drug used by men to grow there muscles. This is mostly used in professional sports, but mostly Major League Baseball. A perfect example of steroids in Major League Baseball is the New York Yankees. Steroids let you do things in baseball like hit homeruns using only 50 or 60% of your power because you are in therepy.

Also see:
New York Yankees, Jason Giambi, Gary Sheffield, Alex Rodriguez
And theres another homerun by Alex Rodriguez, it looks like he used only half of his power in that swing yet he hits it over 400 feet, I wonder why that could be.

Synthetic forms of testosterone, anabolic/androgenic in nature, which, when researched, scrutinized, and applied correctly via the oral, injectable, or transdermal routes in combination with a well-planned and executed diet, consistently intense and strictly methodical gym work, and regular sleep patterns, will, to varying degrees and depending largely upon genetics, produce a physique possessing a state of musculature seldom witnessed outside the realm of hormonal enhancement.
Based upon the extreme and relatively sudden hypertrophy of my girlfriend's trapezius muscle, I'm willing to wager my wife's collection of rare porcelain dolphins that she's secretly undertaken a course of steroids.
