OP you have some good Questions asked by Meg. He's right on with his post.
What I wanna tell you is that by what you ask it is apparent that you need much more knowledge of the safe use of AAS . Where did you get the idea to use Letro for am AI ?
You need to understand esters
As Meg said you should be injecting Sus EOD.
Read up on PCT and understand the profiles of Clomid And Nolva
Back to the books.
By the way what are your complete stats ?
