Once the MLB labor dispute in the mid 1990's, numerous men and women believe that Major League Baseball has been in the "Steroids Era" ever since. Numerous high profile MLB players have been completely accused of steroid use along with a few, like Jose Canseco, also admitted it publicly, crediting the use of steroids for the whole profession of his. In reality, Conseco published a book known as "Juiced" which identified the use as well as effect of steroids in baseball.
Based on Canseco, up to eighty five % of MLB players currently taking part in today use performance enhancing drugs. Jose's book titled "Juiced: Wild Times, Rampant' Roids, Smash Hits and just how Baseball Got Big" names many well known players who have used steroids during their pro careers.
Another player, Ken Caminiti, came forward about the steroid use of his and detailed the harm the drug has done to his body. Caminiti admitted that his body had primarily stopped producing testosterone and that the testicles of his have become much smaller. As a matter of fact, his body just had 20 % of the normal level of testosterone. And although Ken Caminiti clearly knew the damage it did to his body, he still confessed he will have done it all once again if he'd another chance. Ken ultimately died as a result of his steroid use. (from Wikipedia)
Many beloved MLB players have stood accused of utilizing these performance boosting medications. Names as Barry Bonds, Sammy Sosa, Rafael Palmeiro and Jason Giambi have been tarnished by the claims. Their records as well as awards have all come under question since they were not achieved easily, but with chemical help banned by MLB commissioner Bud Selig.

A business referred to as BALCO, the Bay Area Laboratory Co-Operative is actually cited as a main source of best legal steroids to athletes in many sports. BALCO was an American based nutritional supplements company run by Victor Conte.

BALCO designed and marketed a steroid dubbed "The Clear", also called THG, or tetrahydrogestrinone, which was invented by a BALCO chemist named Patrick Arnold (from Washington Post)
In 2003, the company's role in a drug sports scandal was examined by 2 journalists; Lance Williams and Mark Fainaru-Wada. The scandal was defined as the BALCO Affair and centered on the division of the Clear to many high profile athletes in Europe and America over a period of several years by Conte, Greg Anderson, a weight trainer and Remi Korchemni, a coach.
The investigation was aided by a tip from US Olympic sprint coach Trevor Graham in 2003. Graham supplied a syringe containing traces of the substance known as "the Clear". An exam to identify the Clear was created and some 20 Olympic category athletes tested positive for the drug. Marion Jones, an Olympic track star, simply admitted to using steroids after years of public denial. She stated she used them to plan for the 2000 Olympics in Sydney and also the Olympics committee has now taken away all her medals. (from the Washington Post)
