It all depends on your blood work... What your total testosterone level is. If it is not between 20-60 ng/dl... And is above that range, you might want to discuss it with your doc. Similarly, if your T level is between 0-15 ng/dl you might consider adding a testosterone supplement in the form of cream, if you feel tired, lethargic, low enegy, or have a very low libido.
I'm postop and take neither an andro-blocker, nor a testosterone supplement. But my blood work also backs this up as well. Get your blood tested and talk to your doc.
