I'm a firm believer in "if it sounds too good to be true then it is". I also hate wasting my money so I thought I'd share this with you. Hope it helps clear up some things for some of you.
You will never find an industry so full of bs and impossible promises in your life as you will in a supplement store.
Once you get past the big gym words and cool sounding ingredients, most of the random supplements out there are just complete crap. Protein and carb powders aside, some of the results and "scientific explanations" they are advertising are to the point of ridiculous. "hgh" pills with no hgh, "vascularity" pills, mass gainer pills etc .
I think the main problem is that we are still quite unexplored in the areas of physical training and supplementation, and as a result there is no way to put laws down on things that dont work, because there is just no way to prove they dont.
Take some of the stuff you see on tv at 3am for example. You know deep inside that standing on those vibrating plates for 5 minutes a day isnt going to turn you into arnie, but theres no way to prove that, and as a result they are legally allowed to rave on and tell you it does work.
In a nutshell, I think everyone will be plagued with bull**** supplement pills, drinks and miracle machines until there are government accepted trues and falses in bodybuilding and supplementation. (which is probably never)
ps. not saying all supplements are complete crap, but most of them are.
