Following a low does cycle of Test E 400mg/ week for 9 weeks, when would one notice estrogen levels starting to decrease? I know its recommended to start PCT 14 days after the last Test E inj. Fourteen (14) days after the last Test E inj., what levels would one see on a blood test for test and estrogen? I would assume that the test levels would be dropping and unless PCT was started, would continue to drop. Not sure on the estrogen though. The reason I ask is, I have developed an allergy to my current AI and dont have another to replace it. My last Test E inj. was 3 days ago. Problem is, I am still holding a lot of water and I fear that my nipples might start to act up if my estrogen levels get too high. Any info regarding the above would be appreciated. Thanks.
