suggestions and opinions please. any1 who can help me with a comparison? I've done a little research on the bd as well as on their respective websites. aside from the major $$ diff I also note tht HF37 has more amino acids? or cd I be just as well off to purchase the less expensive HE and buy my own addl amino acids? suggestions for AAs wd be welcome too. or do some of you who have either exp both or swear by either think that you get what you pay for? thanks girlfriends!
