I just ordered som letro from ar-r and I am currently taking liquidex and nolva. I want to switch to letro because the l-dex seems to be not doing the trick any more. Nips are a little sore and I have had gyno surgery before. Any suggestions on how to cross over and switch succesfully? I know both have to be in your system for a decent amount of time to work properly. Help please! :unsure:
