I've used CL PURPLE WRAATH and i'm almost done with it. Cant say the true results off of it, but workouts are always good with it, and I'm usually a little vainier.
There usually isnt a day I have a really bad workout and they all go well, so its hard for me to gauge sometimes how well a product works.
All you can do is try them, if they work they work, if they dont they dont. Test it for yourself.
I do the same. Sometimes a product really interests me so I give it a shot.
But most the time I take nothing, and rely on plain old food, my multi, fish, flax and green tea. And I can promise you that I look better than 90% of the people at my gym, and some who prob pop 6 different bodybuilding supps as well. I've said it before, and i'll say it again. A supplement alone, WILL NOT determine the outcome of things. You could take them all, but if everything else sucks, they wont do any good.
I mentioned this in that supplement question thread about... I bought, X, Y, Z and how should I take them, yet he has just started working out.
Supplements are NOT an easy way, or way out. You still have to do stuff. Its like when I hear... Dude, the guys on roids I have no respect for. Hey, I dont do them, but they dont get like that JUST by shooting the juice. If it was that easy, we'd all be doing it.
Point being, make sure you aren't stacking 3 or 4 supps and then wussing out on everything else.
