In 2002 the major league players and managers agreed to begin limited, anonymous testing for steroids. Two years later President George W. Bush took the unprecedented step of condemning steroids in his State of the Union address, saying the use of the "dangerous" drugs in baseball, among other sports, "sends the wrong message that there are shortcuts to accomplishments, and that performance is more important than character." That same year, standards grew tougher and major leaguers submitted to their first mandatory steroid tests. Under the penalties first introduced for doping in 2005, 12 players were suspended for 10 days each.
As this anabolic steroid is not very liver toxic, in-fact it is quite mild it can be used for extended periods of time; if you are not susceptible to DHT based side-effects you could reasonably supplement with Proviron the entire duration of your cycle. While it can be used for extended periods, as we will see dosing protocol can vary dramatically depending on the purpose for which it is used. If Proviron is being used simply as a quasi-anti-estrogen medication then a mere 25mg per day may be all you need but many will find 50mg to be needed if their cycle contains a high dosing of aromatizing steroids. For those who are supplementing for additional beneficial purposes higher doses may be needed; although 50mg will provide them solid effects a slightly higher bump may be needed. If you choose to use Proviron this is something you may need to play with as individual response will vary greatly. For the individual who supplements for the purpose of bridging, a rather common purpose of Proviron use, doses will necessarily be much higher, ranging from 100mg-150mg per day if the individual is going to obtain the desired effect and benefits.
One drawback to Brennan’s study is that, unlike Kouri’s, there was evidence of attempted deception. Several people had to be excluded from the non-users’ group because they were either definitely on steroids (they failed the urine test), or probably on steroids (in the researchers’ words, they had “implausibly high muscularity and low body fat despite denial of AAS use”). However, even if a couple of users slipped in, they probably didn’t skew the data too much. The sample size for nonusers was big enough (131 people) that a few bad apples wouldn’t spoil the whole bunch, and the researchers were excluding suspiciously jacked people anyways, so if a few users did slip in, they apparently weren’t swole enough to raise any red flags.
