There is a story on cnnsi.com about MLB steroid testing and this paragraph was interesting.
Identify trans-dermal synthetic testosterone as a major problem. Who knows if Conte is close to being accurate at his 50 percent guesstimate of usage? It's a number pulled out of the air. But don't get hung up on percentages. The point is that for all sports these fast-acting creams, gels and patches have become a preferred method of testosterone delivery.
The major benefits to these drugs -- because dosage and duration need to be controlled to avoid detection -- seems to be more in the line of recovery and endurance than anabolic gains.
But also know this: Only an idiot would use synthetic testosterone without combining it with HGH. Why is that? A study done in Australia, according to Wadler,
showed that even low doses of testosterone provide greater performance-enhancing benefits when combined with HGH. "More bang for the buck," as Wadler said. Now remember that baseball players get what amounts to one announced HGH test a year (when they show up for spring training). So if you are a player who already has dismissed the moral obstacle and decided to cheat by using synthetic testosterone in low dosages, why would you not use an enhancer, HGH, that comes with a zero percent risk of getting caught?
