Well, clomid won't work to elevate test levels beyond what they would normally be while off cycle. It only works when test levels are low. Clomid increases FSH (follicle-stimulating hormone), which stimulates produciton of sperm, and LH (luteinizing hormone), which stimulatesrelease of testosterone. However, you still have a negative feedback loop to worry about and that's what regulates hormone levels usually so that when various hormone levels get too high, a negative feedback loop slows down production of that hormone either directly or indirectly. That's why clomid won't work unless test levels are low to begin with. There's some info for ya.
