Here is why I find this story far more egregious than hearing of an Italian 24-year old who was busted for EPO.
Guys who are the Masters professionals fit the demographic of someone who has some kind of a career, education, possibly family, and perhaps found cycling a bit late and instead of a tryst with a young waitress, endeavor to approach cycle racing as their mid-life crisis. This kind of vicarious re-birth, and an often deep savings/bank account, leads to a temporary suspension, or complete flushing, of ones sensibilities.
Not knowing anything other than my speculations above, I find DHEA to be suspect as well. Not a true "enhancing" substance, the thought it was bridging a cycle only serves as smoke for a bigger fire. Without anything else, I find this to be far more damaging to the sport, as it impacts the grassroots racing communities and sullies the regional racing scene, driving people away from the joy of competing.
This kind of mentality is best pointed in the direction of the local gym, where guys like this can "be all they can be" and pump weights, and each other.
