In a study that brings back memories of the one that “proved” that a four-minute mile was impossible, a professor is claiming that steroids can increase homerun production 50-100%.

The such a study could be taken seriously beggers belief. Among other things, if such a benefit from steroids were real, home run rate would have exploded across the league and this is clearly not the case. The people who have tested positive for steroid use, including many pitchers, have not had anywhere near the power explosion this guy is guessing at.

(Although it clearly would depend on the type of hitter. You could add 4% to the speed of the balls I hit and they might just reach the outfield. Adding 4% to Barry Bonds is a different story, clearly.)
