if it was a doctor he was probably talking about using 1-2iu for rejuvenation purposes. there's a big difference between using split dosing vs single dosing.
do explain
I feel like falling asleep after shooting 7iu+ in one pin. I split up 10iu's into 5iu subq in morning and 5iu IM PWO but I hear some many conflicting reports...this works fine for me at moment but I'm going to experiment this week with 5iu subq in morning and 10iu PWO (15iu total).
