Not sure how you can blame someone else for what you pin/take/eat. In the end it's your choice.
You could blame a doctor.
You could blame many types of
actual professionals, really.
But in this situation, you know you are basically paying someone to use their experience in experimentation to further experiment on you.
If I go get my car tuned - I have the ability to say I want a safe tune or I want something that really pushes the boundaries. That's really the type of scenario we have here. A bunch of people paying to be tuned - and naturally, when we're talking about the top competitors, we're talking about people who can either perform better with lesser amounts OR are really pushing the boundaries.
Then you have the guys that are slightly genetically flawed who are trying to get themselves to the top. Hence, unsafe tunes.
