A. Not likely. Athletes and body builders typically use synthetic testosterone made in a laboratory know as "designer testosterone". It is designed to push testosterone to very high levels which usually results in a corresponding rise in estrogen - it stresses the body and is therefore unhealthy. The testosterone we use is bioidentical to the testosterone produced naturally by your body - it comes form plant sources. We take your testosterone to natural levels that you had at age 25 to 30. It is safe and effective.
