Maxititer can you clear this up Igfr3 and peg MGF??

[Juice Freak]

I read that igfr3 and peg mgf taken at the same time will cause an effect inhibiting the formation of new myotubes. Have you read this anywhere??? I know that they don't compete for the same receptors just was always told not to do both at the same time due to inhibition on myotubes??? Can you shed some light on this brohan???
