I'm on it, have been for 2 years. My doc is cool he helps with my cycles and is generous with the test. Get all my blood work done and he has a machine that documents my progress. It sends electrodes through my hands and feet and tells me how much body fat and dry lean mass I have put on every 6 weeks. Honestly its the best thing I ever did because he monitors all my levels and helps with keeping the proper doses of ugl gear in the correct range. Plus unlimited Human Chorionic Gonadotropin (HCG), anastrolzole, cyp aren't bad benefits either. Oh and the sermorelin straight from the pharmacy as well. Keeps me in check and makes sure my cycles are in the proper range. Thats why I'm on it.
