The authors, Mark Fainaru-Wada and Lance Williams, describe in sometimes day-to-day, drug-by-drug detail how often and how deeply Bonds engaged in the persistent doping. For instance, the authors write that by 2001, when Bonds broke Mark McGwire's single-season home-run record (70) by belting 73, Bonds was using two designer steroids referred to as the Cream and the Clear, as well as insulin, human growth hormone, testosterone decanoate (a fast-acting steroid known as Mexican beans) and trenbolone, a steroid created to improve the muscle quality of cattle.
BALCO tracked Bonds' usage with doping calendars and folders -- detailing drugs, quantities, intervals and Bonds' testosterone levels -- that wound up in the hands of federal agents upon their Sept. 3, 2003 raid of the Burlingame, Calif., business.
Depending on the substance, Bonds used the drugs in virtually every conceivable form: injecting himself with a syringe or being injected by his trainer, Greg Anderson, swallowing pills, placing drops of liquid under his tongue, and, in the case of BALCO's notorious testosterone-based cream, applying it topically.
According to the book, Bonds gulped as many as 20 pills at a time and was so deeply reliant on his regimen that he ordered Anderson to start "cycles" -- a prescribed period of steroid use lasting about three weeks -- even when he was not due to begin one. Steroid users typically stop usage for a week or two periodically to allow the body to continue to produce natural testosterone; otherwise, such production diminishes or ceases with the continued introduction of synthetic forms of the muscle-building hormone.
