TweetHas any one felt side effects from small amounts of estrogen left in Dazed's Syno Prop? I've used it with good results and without gyno, but I don't feel 100% while using it. I'm not overly confident on syno like I am on test made from powder. I'm thinking it might be small amounts estrogen, fucking with my head. Because I experienced no gyno, I assumed it had no estrogen. I'm starting to have second thoughts.
