There is no physical evidence for usage of steroids by Roger Clemens

It is known by each baseball fan that Roger Clemens is accused in obstruction of justice. It is affirmed that he has lied before Congress about usage of steroids and HGH.
Rusty Hardin, the defense attorney for Roger Clemens, noticed that there was no any difference in physical appearance of Roger Clemens before, during and after his trainings with Brian McNamee. The attorney claimed that this factor proved that Roger Clemens hadn’t administered steroids and other related preparations.
Enhancement of muscle mass is often utilized by federal prosecutors as proof that a person takes steroids or/and other performance-enhancing drugs. But this tendency was not used during the case against Roger Clemens. No one could claim that muscles of Roger Clemens displayed that he had applied steroids and HGH. It is one of differences between the case against Roger Clemens and that against Barry Bonds.
As for the governmental case against Barry Bonds, feds called many individuals in the trial who were able to testify that anabolic steroids led to obvious changes in physical appearance of this person. They affirmed that intake of steroids caused increase of muscle mass, increased size of the head and shrinkage of testicles in Barry Bonds.
So, Rusty Hardin showed 4 photos of Roger Clemens. The pictures displayed physique of Roger Clemens, including the period of time when Clemens was working with the coach Brain McNamee. The attorney noticed that the pictures showed that there were no changes in physical appearance that could support that he took steroids and HGH.
Rusty Hardin noticed that the photos displayed only the process of ageing. The masseur Cheryl Redfern also claimed that she didn’t observe any changes in physique of Roger Clemens. Roger Clemens experienced neither back acne, nor abnormal development of breast tissue, nor essentially enhanced muscle mass.
Phil Garner a former Major League Baseball player also confirmed that there were not any substantial changes in physical appearance and performance of Roger Clemens during working with Brian McNamee.
Steve Durham, the Assistant US Attorney tried to discredit the argument about lack of changes in Roger Clemens’ physical appearance during the cross-examination of Garner. He confirmed that while certain steroids increased muscle size, others didn’t induce enhancing muscles. Thus, he claimed that the pictures could display nothing about steroid use.
Feds want to take advantages in both cases: in the case against Roger Clemens and in that against Barry Bonds. While they affirm that physical changes in Barry Bonds manifest that he has utilized steroids, lack of physical changes in Roger Clemens doesn’t prove that he hasn’t taken steroids.
