    considering HCG monotherapy

    Hi all, This will by my third, and probably last post about HCG. I have developed a pretty thorough understanding of it at this point.

    Looking for experiences on Test+FSH+HCG

    Thanks for the response Nelson. Big fan of your forum. There's a lot of great information here for newbies like me. I will lower the clomid to 25 ED and see if that's affected my test production then lower it to 12.5 ED if I haven't seen a decrease in serum test. If clomid turns out not to be...
