Hey bro,
If its ok... let's get a new thread started for you on this subject. There's too much info, and I'm sure many will want to chime in. I'm definitely interested, and am happy to share my similar experience.
For what it's worth... having an unusually high natty IGF—from what I've seen thus far, including myself—doesn't necessarily equate to super-high IGF on exogenous GH. There's something going on that I'm interested in uncovering. There may be some answers from Type-II and his book (which I'm reading now).
