Have used Long R3 IGF-1 IM immediately PWO bilateral shots. Lots of localized growth. Not much strength although my IGF-treated bodybarts seemed to respond much better than the rest of my body to my following androgen cycle.

Used 40mcg IM. Personally, I don't see the need for higher dosages, a lot of people are having good success at 20mcg ED IM.

Remember, if the IGF can't attach to the muscle in which it is injected, it will go attach somewhere else and a LOT of receptors are on the intestine. Can you say HUGE guts? Just go for the PWO shot man, you'll be glad you did.
