We want to get your levels to the upper 25% (quartile) of physiological normal. That would be approximately 750-1100 depending on the lab. We do this with physiological doses of testosterone, not pharmacological doses. And as you are more than just a number on a lab sheet, we also want your levels of function and well-being to increase as well. That optimal level that we shoot for is probably the "normal" level for a guy in his 30s. That's where we want you to be.
