Listen to what Mr. Protein said.
Total test levels are viewed by most to be less important than "free" test levels. Free levels are what is available in the blood. Only about 2 percent of testosterone is unbound (bio-available) and
therefore free to enter cells in order to effect its biological actions by binding to androgen receptors. Also, most would say that 300 ng/dl (10.4 nmol/L) and 400 ng/dl (13.9nmol/L) would be considered LOW and merit possible treatment.
Most Dr.'s prescribe crappy Androgel but your best bet is injectable Test. Dr's usually prescribe 200mg every 2 weeks. Below is an exerpt from the Nw England Journal of Medicine (July 4, 1996 Volume 335, Number 1):
"To understand the work of Bhasin et al., it is important to relate the amount of testosterone that enters the blood after the intramuscular administration of testosterone enanthate with the rate at which the hormone is produced in normal men. (3) In men with hypogonadism, serum testosterone concentrations increased to 1400 ng per deciliter (48.5 nmol per liter) two days after the intramuscular administration of 100 mg of testosterone enanthate and declined to 800 ng per deciliter (27.7 nmol per liter) one week after treatment. (3) From these data and the rate of metabolic clearance of testosterone in men, (4) the amount of testosterone that enters the blood after an injection of testosterone enanthate can be estimated. Thus, an injection of 100 mg of testosterone enanthate results in a dose of testosterone almost double that produced by the testes of normal men (75 vs. 42 mg per week)."
