Do i need blood samples if i want to take hormone blockers again?

Hormone blockers?: What are hormone blockers? If they're purchased at the store or the internet they're worthless junk that doesn't do what they say and can harm you. Have you been on anabolic steroids? Don't waste your money and your health. If they're something you received by prescription from your doctor, then yes you do need to be tested before restarting any such medication.
