I'm curious what it is about IGF -1 that causes the vascularity. I'm into my IGF -1 run for maybe 2 months now? Something like that. And I've gotten pretty vascular. I wouldn't say I've leaned out all that much, in fact, I don't think my abs look much different (I haven't been trying to get leaner, so this isn't really an issue). This is making me think the vascularity is not related to fat loss... Anyone got an explanation for it?
