Just to add my experience to this thread: I've been on Oratropin for the past 17 days of a 30-day cycle. This is in the middle of a 1g test/week 50mg proviron/day cycle (it's my third). I've leaned out significantly--people who see me everyday telling me I look downright skinny, even though I've gained five pounds during the 17 days and hit my highest ever max on deadlift today. The overall effect has been subtle, but noticeable. Less localized growth it seems and more overall size, but with less fat. I'm going to finish the Oratropin cycle, take a month off, then try the injectable version to compare. Any thoughts on which grade of IGF-1R3 to use as a comparison? Anyone at IBE labs wanna spot me the injectable stuff for a month if I agree to post a head-to-head comparison? j/k
