If you have been on cycle and your estro levels are elevated running a SERM for PCT will increase test levels only until its stopped at which point test levels will plummet again because estrogen hasnt been managed.
High estro= dropping natural test levels
Low estro= rising natural test levels.
SERMS do not lower estrogen. They are technically estrogens with no effect at the receptor sites.
Great for stopping gyno.
Great for estrogen driven breast cancer
Good for kicking up test levels but they should ALWAYS be run with an AI. This way when your PCT is done estro will be low and test will be high.
If you run a SERM only youll have elevated test and elevated estro because, estro was already high plus rising test levels will further increase estro levels.
So....you stop the SERM and test plummets. PCT FAIL.
PCT-
AI only plus other test boosting compounds.
AI plus SERM.
NEVER- Serm only.
