i agree 100%.
......but talking about the proven, time tested supplements like whey+casiene, creatine, glutamine, bcaa's, green tea extract, fish oil, caffiene,, vitamins, dextrose/waxy-maize(vitargo)...taking all of these, or any combination of them, can be very beneficial for a bodybuilder. but you already said that.
for myself, i have found that even whey protein isnt needed when im eating alot of solid protein meals leading up to my workout. but everybody is different. and i dont have problems putting on size, i have problems staying lean.. so for me a supplement like green tea ,fish oil, vitamins, caffiene, creatine, and glutamine are essentials..where for another a different combination might be better.
I will say in defense of the "hype" supplements that for people with alot of extra spending money whose main hobby is bodybuilding, and who dont want to take anything illegal......some of these supplements can be slightly, even moderately effective. but they are just that= supplements. where i disagree with these people is when you see soemone whose diet is shitty, and trains like a little girl, And thinks a 200 dollar shopping spree at gnc is going to off-set the fast that they have a shitty diet and dont train hard.
but for someone who is 100% dedicated and just likes to spend time and money on their bodies....getting a pre workout supplement like no-explode or horse power or nano vapor would be fine...and trying out different legal pro-test supplements wont hurt.
