Highly confused and suspicious of pricing? What? You need to learn about this dude Socrates. I think he'll help you understand. Sometimes, things are not as they appear - especially questions.
In any event, I did "dig deeper" by extensively researching the history of this topic on this forum and verified, after multiple searches, that the claims of the gang in this forum regarding Primoblan "crashing" estrogen are not more than 3 years old. No one 10 years ago or 5 years ago was claiming this.
We also have a good scientific contribution that indicates ALL DHT derived androgens reduce estrogen, which I consider plausible, but not to the degree being claimed here.
Outside of using AI to summarize (correctly) why some random aromatase inhibitor researched by Schering in the 1990s is not a metabolite of Primoblan, I have not used it. And this should be evident by my writing style.
