your a fan of taking niacin pre working out for increased growth hormone.. but is there ANY evidence increased growth hormone does anything positive? I´ve only read a study that showed HGH increased muscle mass but not strength.. so I´m guessing it was just bloating. Also there are plenty of athletes that have had pituary problems that resulted in agromegaly.. those guys must produce insane amounts of HGH 24/7, yet they aren't that muscular at all. In fact athletes with acromegaly seem extremely slow moving to me(bigfoot silva, nicolai valuev etc.).. which seems to support added body weight without added strength/speed.
