The endocrinologist I used to use would emphasize how important having bloodtests done every three months. He said that it's not the dose, it's the serum levels that are important. That you are shooting blindly without tests. With the atmosphere of fear in the weight training world now, it is impossible to find doctors willing to be at risk. My first gym membership was at a big YMCA, and the front desk had a list of sport clinics where you could get guidance. I am so slow to want to inject anything not made by a pharmaceutical company.
