There is no excuse to suffer from estrogen related issues while on testosterone. If you can afford testosterone you can surely afford estrogen to keep you safe. Thousands of guys use testosterone and never invest in an anti-estrogen and because they don't experience side effects or experience them later they refuse to invest in them. Stop being cheap. These are mistakes that young people who should not be using these products make. I'm seeing more grown men make this bad choice. It's just crazy not to protect yourself. Top products are, Arimidex, cabaser, femara, clomid, HCG and Aromasin. No excuse to not use with testosterone. No one to blame but yourself. If you can't get this from your doctor or however, don't use the test until you do. It won't kill you but it defeats TRT purpose.
