Can you have high estrogen without getting gyno or tender nipples? The lethargic feeling and low libido are quite strong so I do believe that's what it is. Could the high estrogen keep me from feeling the effects of the test e? I have liquid aromasin on hand. What about .5 ml eod to start with? I haven't used it yet as side effects were minimal, but this decreased aggression and low libido are killing me.
