I take Citrulline Malate made by prima force. You can get it at a decent price online. I take 8 grams a day. Taste sour but bearable.
Citrulline Malate is a precursor to l-arginine and seems to work way better then l-arginine alone. I think read some where your liver takes out a l-arginine supp. But not CM. Along with a very nice N.O. boost, it increases ATP production in the body. Basically creatine and pulls ammonia out of your body. It can also give a little growth hormone boost.
Forget cialis go with Citrulline Malate…more natural. It’s an amino acid.
