From what I understand yes, you are correct. The androgen receptors in the mandibular region are pretty dormant without the use of AAS. As we use these muscles constantly, they will grow like any other muscle when stimulated. Even the guys in fitness mags are on drugs, just usually primo and anavar. Sure, there are some that really are natural, but they're far and few between.
Yep, I take a ton of vitamin C and hardly am ever sick. I think all the stress I have going on from some crazy courses this semester coupled with financial aid fucking with me finally dragged me down. I might be sick once a year otherwise - and that's usually from food poisoning haha. I just can't say no to chicken, even if it might smell a bit off.
