I don't post on forums much, but I read a lot. Being as though I've had experience with them I figured I'd give my 2 cents. I've used Bluesky Nolva, Aromasin, and IGF-1 LR3. Aromasin I had to dose higher than pharma grade, but it worked. Nolva was pretty spot on and I got excellent pumps from the IGF-1 LR3. Sometimes the pumps in the shoulders were almost unbearable (in a great way). That was my first trial run with IGF-1 LR3 and was very happy. I gained approx 6 pounds without changing my diet. I've since ordered a few more vials of both IGF-1 LR3 and Des to run together, but I haven't started it yet. I also felt slightly hypoglycemic (sp?) if I didn't eat carbs almost immediately after injection.
