There is nothing wrong with doing the slin at both times with 10iu's. I find taking slin with LR3 (together) to be uneccesary, the LR3 doesn't bind to proteins so the half life is long and your natural insulin isn't inhibited to any great degree, but your Blood sugar will drop excessively when taking both together so i'd up the carb intake if your gonna run both at the same time PWO. I really find the LR3 works fine on it's own..it's not like GH--that's a different story?Originally Posted by joevette
