I currently am using Humalin-r (was unable to get humalog at start of cycle) twice a day on workout days. 4 iu's 1/2 an hour after morning cardio and 6iu's PWO. On days I dont weight train I just use 4 iu's after morning cardio. I have been doing this for about 9 days and I must say I love the results. I am bigger, harder and much fuller. Today i recieved my Humalog and I was wondering is it okay to use the Humalog PWO only and still keep the humalin-r for morning injections? The only problem with humalin-r PWO is I have to stay up so late to make sure I am outside of the peak time frame. With Humalog I could crash out after 4 hrs after my injection. I just want to make sure using two differnet types of insulin during a cycle does not create some very bad sides. thanks.
