I don't know for sure. Nobody does except for Bonds, Clemens, and anyone who may have witnessed their injections. Literally anything else is heresay.
Me, yes I think they used along with 75%+ of the league. Just like everyone in the 60's and 70s used ampethamines like they were candy, and even had a cockatail called "red juice" that was extremely common in the 70s and 80's.
Are amphetamines the same as steroids? No. but they still helped players perform better or they wouldn't have used them. They were also illegal.
What pisses me off the most about this, is that these writers have NEVER historically given 2 shits about players that used performance enhancing substances, but somehow steroids are seen as this miracle substance that turns terrible players into Hall of Fame talents and they "needed" the steroids to be good at baseball. It's such a ******** argument. Players of the past didn't "need" amphetamines to be great ballplayers, they just used them to enhance their own talents and perform at their peak for longer. Steroids did the same thing, just better.
The hypocrisy of the writers that don't vote for alleged steroid abusers is astounding. Unless they were in the room when the injection happened, they don't KNOW anything. But since they don't like Bonds and Clemens because they might have been *******s, they use the steroid thing as the excuse to keep them out of the Hall.
These are the same writers that covered baseball in the late 90's, with dwindling attendance, s***** national visibility and lower revenues due to the 1994 strike. Then the HR chases, the records being broken, huge surge in popularity and NOT ONE OF THEM said jack s*** about steroids at the time, because they were making their living off the renewed popularity of the sport. Any writer that didn't vote for alleged steroid abusers while making money off what they did, are dirt-bag hypocrites who's opinions aren't worth the paper they were printed on at the time.
Every single one of them should give up their vote and f*** off into the sunset.
