To juice or not to juice...
The Natty Argument
The Advocate's Devil
Protein shakes will not magically add pounds of lean muscle to your frame if you do not lift heavy things; the most that they can do is reduce the pain and soreness associated with hard workouts, since the amino acids hit your bloodstream quickly and easily. But if you already eat a lot of lean protein by way of chicken, grass-fed beef, fish, pork, and so on, then protein shakes won't be of significant benefit for you beyond maybe reducing soreness.
Fish oil capsules will have little effect if your diet already includes large amounts of grass-fed beef and deep-sea fish. The major benefit of creatine is that it simply allows you to work out just a little bit longer, by allowing your muscles to keep working just a little harder. But that increase in work capacity is not particularly large; indeed, there are natty lifters out there who argue that creatine monohydrate simply does nothing for them.
All PEDs Are Not Created Equal
Drugs in Sports
And in Mr. Armstrong's case, of course, he lied about it an then secured Federal funding to the tune of something like $15 million, last time I checked, for the US Postal team. That wasn't just lying- that was defrauding of the public.
A Way Forward
In the drug-tested leagues, if you get caught, you are banned. For life. No ifs, ands, or buts. No excuses will be tolerated. In the open leagues, take whatever the hell you want. If you kill yourself, that's your problem.
What I suspect will happen is that money will rapidly move from the drug-free leagues, to the open ones, in very short order- because the open leagues will be the most interesting and exciting. But that's largely speculation on my part.
Perhaps it is time to recognise that reality, and act in accordance with reality, not with how we desperately want things to be.
