A few things here.
First, just because he got caught taking severely under-dosed GH doesn't automatically discredit everything the man does. A lot of what he says and does is great and I think many people could benefit from it. High protein, low carb, sunlight, rest, natural lifestyle etc.
Secondly he didn't do anything every single bodybuilder in history hasn't done. They have all put their name on a product and it sold based on peoples ignorance and at the time they were making that cheese not a one came up and said what they were taking. Hell, some still deny taking anything 20 years later.
Lastly, I keep hearing about Muscletech supplements. Say what you want but Muscletech was some of the first supplements to come to market that actually did any damn thing at all! 99% of the bodybuilding supplements on the market at that time were pure shit. (weider protein chalk powder that you couldn't mix with a fucking ninja blender and amino acid tablets that would choke my ex who had no gag reflex) Did they make you look like the guys on the mag covers? Of course not. But they did work. I gained quite a bit of solid muscle on the stack. The original Hydroxycut is still one the best things ever invented in the supplement industry.
