I have read the write up. However, I'm not really clear on something. Is this product a stimulant? Or is it a CNS stimulant? For some people, mainly ecto's and skinnyfat ecto's, stimulants are extremely detrimental to building muscle. For others, they can take stims and it has little to no negative effects on building muscle. Anyway, I just wanted to make sure it was not a stim or more importantly a CNS stimulant.
