Free test is the only kind that matters. Yes, the fadogia will maintain healthy LH levels in-between cycles, I just don't know if a blood test will tell you how much of a difference it would make. If your LH is naturally way low -- like 0.4 and the fadogia triples it, to 1.2, it's still going to be low -- in which case did the BRIDGE do nothing? No, it did a lot, but you'd need before and after numbers. However, if you did areasonable cycle, then a proper PCT and then went on BRIDGE I would assume everything would come back looking really good.
