Thanks for your suggestions!
I'm not stupid, I know what I'm going to meet!
Unfortunately a real SERM I can not find it very easily ... asking to make me do a prescription from the doctor seems impossible.
I read so much before starting to use a SARM, LGD.
I also read that it does not need a SERM at the end of the cycle, since (by reading some of the feedbacks), this was not needed, as it was not suppressive as it was suspected.
I know it's an unconscious risk, not stupid (otherwise I would not read anything about it).
I could also stop here, at 4 weeks, and do not go any further (8 weeks), not to complicate things.
