No changes were seen in physical appearance of Roger Clemens before, during and after working with McNamee

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 claimed that Roger Clemens’ muscularity didn’t change greatly before, during and after his working with Brian McNamee. He confirmed that this aspect proved that Roger Clemens hadn’t used steroids and other related products.
Increase of muscle mass is usually utilized by federal prosecutors as proof that a person uses steroids or/and other performance-enhancing drugs. But this tendency was not used during the case against Roger Clemens. No one could affirm that muscles of Roger Clemens manifested that he had used 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, federal prosecutors called numerous individuals in the trial who were able to testify that anabolic steroids caused significant changes in physical appearance of this sportsperson. They confirmed that intake of steroids led to increase of muscle mass, increased size of the head and testicular shrinkage in Barry Bonds.
Thus, Rusty Hardin showed 4 photos of Roger Clemens. The photos manifested physical appearance of Roger Clemens, including the time when Clemens was working with Brian McNamee. Hardin pointed out that the pictures displayed that there were no changes in physical appearance that could manifest that he applied steroids and HGH.
The attorney Rusty Hardin noticed that the pictures manifested only the process of ageing. The masseur Cheryl Redfern also confirmed that she didn’t observe any changes in physique of Roger Clemens. Roger Clemens had neither back acne, nor abnormal development of breast tissue, nor dramatically enhanced muscles.
Phil Garner, a former baseball player, also affirmed that there were not any substantial changes in physical appearance and performance of Roger Clemens during working with the coach Brian McNamee.
Steve Durham, the Assistant US Attorney tried to discredit the affirmation about lack of physical changes in Roger Clemens during the cross-examination of the former baseball player Phil Garner. He claimed that while some steroids increased muscle mass, others didn’t promote enhancing muscles. Thus, he affirmed that the photos could display nothing about steroid use.
Federal prosecutors desire to take advantages in both cases: in the case against Roger Clemens and in that against Barry Bonds. While they affirm that changes in physical appearance of Barry Bonds manifest that he has used steroids, lack of physical changes in Roger Clemens doesn’t prove that he hasn’t administered steroids.
