BTW thanks for the comment jminis, glad to see someone else is still reading besides sticks.
I'm following this regularly as well.
I'm doing something similar myself, using IGF-1 to bridge.
So far, I've only gone as high as 40mcg per day. I'd love to try higher, but it's worked awesome for me. I retain some water on IGF-1, not as much as aromatizables, but a moderate amount. I seem to gain size and shape very well on IGF-1. I owe a lot to it. I believe it's solely responsible for giving me a bodybuilder look, (as opposed to an ordinary dedicated lifter). Even now, 2 weeks after finishing a bottle of IGF-1, the muscles look bellied and fuller than the end of my cycle.
Also, I've only used it post-cycle. I'm on a budget, and to me it makes more sense to use my the resources I've got to solidify my gains. But damn I would love to try this during a cycle.
I've gained 3 or 4 pounds after finishing my cycle, while dropping water weight. My strength only increased on a few lifts and remained the same on all the rest. This time, the second time I've used IGF-1, has been my best PCT ever.
If I had the money, I would go on like this forever, using IGF-1 for bridging.
I'd also like to try IGF-1 with Humalog some time. Maybe next PCT.....
