I never said an elevation in estrogen ramps up GNRH,FSH,LH. Its the opposite. A LACK of estrogen causes this because, the brain/body, seeking homeostasis,
will send leutinizing hormone to the balls so more test is made for the purpose of making more estro via aromatase.
It is true that blocking the receptors will do this effectively and pretty much all SERMs do this to some degree as most have a high affinity for the receptors in the brain that regulate this negative feedback loop. Most also have super strong affinities for the receptors in breast tissues which of course is why these drugs are made.
But again...if you just lower estrogen this will also happen. The reason in my opinion the AI choice is better for most is this...
Say you run 500mg test for 10 weeks. Test is high and estro is likely exceptionally high as well....ESPECIALLY with all the guys parroting that there is no need for an AI (thats another conversation entirely).
Anyways...if you employ clomid/tamox torem etc ONLY...it will basically trick the brain into thinking estro is low so test will rise. THe problem here is that upon cessation of treatment with the SERM ESTRO IS STILL HIGH! So....test plummets and a month post PCT your in bad shape again with test low and estro high.
THis condition can persist for years...I have seen personally this happen in several people I know unfortunately including myself.
It was this that started me on the path to create a homebrew AI which became FOrmeron.
I dont at all mind stimulating conversation with you as long as we dont argue about our brands respective products.
Im not stupid enough to believe Im always right though. Nobody is perfect
