Is this poduct any good?
Someone recommended this to me for muscle gain.
Also after taking this product do I need to take anything to keep my natural testosterone up?
I heard that some products will make your body stop producing it.
Also, do I need to worry about my liver? I have heard that sometimes it is a good idea to take something to cleant he liver as well depending on the product.
I have never taken anything other than creatine and protein so any help would be appreciated.
