Hey user, I'm seeing a lot of misinformation in this thread about "killing your liver" and irrelevant debate about military. So i'll actually answer your question, since no one else wants to.
I've attached the complete nutritional info for their product "D-Bal".These geniuses have decided to sell regular fitness products, in this case BCAAs, re-labeled as "legal steroids", in the hopes that jabronis will buy their overpriced trash thinking they'll make sweet gains.
The reality is that you're paying $90 a bottle (yes you read that right) for what is essentially astronomically overpriced BCAAs, so no there is no damage that can be done in taking these products.
The only damage this product will do is to your wallet, as the money can be better spent on food. I promise you user, proper nutrition, and not just eating alright here and there, but real painstaking proper diet is the core of bodybuilding, not supplements.
Moreover, the fact that you're asking a Mongolian sheep herding forum about pseudo-steroids, rather than researching it yourself proves that you're not ready to ride a bicycle anytime soon.
I know its harder to do it the natural way and it might not be what you want to hear, but without building a proper foundation in nutrition, you can take all the real gear in the world and you'll still end up looking like shit.
Godspeed user.
