It's really not surprising your doctor(s) don't have a straight answer to give you, since Test. levels are somewhat of an art as opposed to an exact science. And, since you're throwing in a 4 month cycle every year, that's going to skew your results even more. Your age is also a factor in the entire equation. Anyway, I think the only way you're going to figure out exactly what's going on is to not do a cycle for a year or so and see where your Test. levels are at. It's quite possible you have naturally low Test. production and/or have some done some permanent "damage" to your hpta system due to your previous cycles...Good luck...
