Riddle me this: OP, what would you have done if your bottle of EPI happened to mysteriously vanish from the face of the earth say 5 weeks into the cylce when your GOOD and SHUT DOWN and you have no post cycle therapy (pct) on hand to bring your endogenous test levels back to balance? You would have had to wait at least two days + whatever time it took you to find out how to use your SERM... your hormonal system would be seriously FUCKED that's what would happen. People like you are why we saw the near god like 4ad, 1ad, 1-test, etc banned back in 2004. Do your research before playing with grown man supplements next time.
