TweetId start off the 3iu and go up to 4iu split twice ed if you don't have bad sides with the 3iu. Ive heard ppl doing it five days ew with wk ends off and still getting good results, and theres others saying 7 days ew for 5-6 months is the best if you can afford to do it. Id ask Big Mike hes doing it. I think you do it sub-q with a slin needle or with a 5/8" needle almost all the way deep, but make sure to rotate inject areas.
