Does anyone know for sure what LR3 IGF-1's halflife is? Someone says 20 minutes.. other say 20 hours.
Regular IGF has a very short halflife, like 20 minutes or something. That's why the LR3 version is so much better. I've heard anywhere from 16-24 hours, but nothing definitive.
I do know I've had good results with only 1 inject a day.
