Just a reminder for anyone thinking of asking. Over the counter drugs such as 6-OXO, T-Bomb 2, Off-Cycle, etc.. are not a substitute fo a proper PCT featuring clomid, nolvadex, and arimidex. For all PCT please refer to Pheedno's PCT sticky. Do not use OTC drugs for your PCT.
Tribulus is an exception when included in PCT. It ofcourse can be used along with clomid,nolvadex, etc, but not as PCT alone.
