I have a question about 7-keto. In an article on t-mag's site, Patrick Arnold says 7-keto belongs to the 5-AD family. He also says that 5-AD has estrogenic properties. I've also read though that 7-keto does not convert to either sex hormone. Can anyone clear this up for me? Is 7-keto going to give me testicle shrinkage or gynecomastia (breasts)? Thanks.
