Some do every day....some EOD, some E3D or even weekly ...
seems to be based on trial and error and what works for you. I am about to order for the first time.....and I think I like the E3D option initially. I will l post what happens.
I used to get mine at the feed store.I would take 1cc and sqiurt it in my mouth everyday about 15 minutes prior to working out.On the weekends I used to give it to my whole paintball team before a game and then 1 more cc before we started the finals.It always helped with energy and I am not sure about wieght lose because I was taking all kinds of stuff then.
