How can you say that it doesn't work to help lower E2 when there's several people that say that it does ? (Through BLOODWORK no less) Primo doesn't aromatize to estrogen, but can functionally lower estrogenic activity for many users, maybe it doesn't work for you, that's not to say it doesn't work for somebody else, everybody responds differently to certain things for you to outright say that it doesn't is just stupidity at its finest, you're always on here having some kind of confrontation with somebody, I think you have a closed mind. Why don't you you STFU
