Can always have three leagues: no testosterone exposure, testosterone exposure and open. Or, None and open. By testosterone I mean any of the related compounds that have similar biological effects. This should reduce the effects as described in the article. I’m trying to discuss the features of skeleton and muscle mass only. It’s a struggle choosing jargon and hopefully limiting it to biochemistry works. Edit: perhaps ranking leagues by size, height, weight and/or percent body fat will partition them more safely. This might be required to address those with steroid insensitivity.
