I have asked questions on teslac before and didnt get much response. I have two books with info on it Body Opus, and World Anabolic Review. Both books lean favorably to it use and compare its testosterone stimulating effect to the same as HCG,just not nearly as fast as HCG. Its also been said that it can lead to an irreversible and permanent suppression of estrogen. However these are old books and that is an old drug.
