Perhaps this has been asked before and if so excuse me in advance.
So I stopped in my local GNC and bought as usual Amino Fuel (Twin Labs) which has worked well for me in the past 2 years or so... Since my body can't tolerate any pre-workout supps. (NO Explode, NO2 Black, NO Shotgun etc.) I'm thinking about taking L-argenine which is way cheaper too! But how heart healthy is it?? I already made some research on the product and I know it's an amino acid and that Amino Fuel alone has a considerate amount of it, but how safe is it taking 500 mg or 1000 mg of it?? Would I even benefit of it since my current goal is to cut??
I have never been diagnosed with cardio deseases or anything (I'm 23 male), but all the above NO products caused me tachycardia and sent me to the hospital once!
