Because estrogen is part of the negative feedback loop of the HPTA, Letrozole (and other anti-estrogens) are able to raise testosterone in male subjects. Letrozole was studied in men, and found to significantly increase LH levels to a 339 and 323% in the young and the elderly, respectively and Testosterone by 146 and 99%, respectively. (3) Letrozole was also able to produce a peak LH response to Gonadatropin Releasing Hormone equal to a 152 and 52% increase from baseline in either young or older men, respectively (3). In a similar study 0.02 mg of Letrozole increased testosterone by 45% after 2 days.

I've done a lot of experimenting with Letro lately and I have to tell you that I will never do a PCT again without it.
It was proven that Letro can raise natural testosterone levels by up to 150% and believe me it is true. It achieves this by causing a positive feedback-loop relating to LH production ect. It does kill your sex drive, but that is only the case on doses higher than 1mg per day.
