It all depends on how good your stuff is, theres alot of crapp going around. You could probably back off on the dose some maybe 60-80mcg i dont think more is better. Your not going to see big results while using or even months after, it may lean you out some while using and give you some pumps but actuall muscle growth takes a long time months and months. But what you should do is run a bulker couple weeks after the IGF cycle and EAT/TRAIN HEAVY so you could really push those muscles into new growth and feed them with alot of protien. Also you may want to try pinning that muscle right before training, the pumps are insane. Or do the PW injections, i dont think there is a big diffrence.
