Mike, School's not out yet Bro, I never said nolvadex and airmidex had anything to do with progesterone aromitization, I simply stated what I know from what I read and heard. And I'm not here ditchin on you about clinical studies. You say we can "make logical deductions on how these drugs would effect other systems within the body - with and without the added steroid compounds" but again that did not answer my question. You simply restated what I know... in clinical terms. I said show me a study that demonstrates what and how we use the different compounds together and or in what combinations, not tell me how they work within the body. If you want to give us a chemistry lesson then go ahead and explain it so EVERYONE can understand in simple terms. I'm sure virtually everyone would benefit from your pharmacological expertise. Follow me?
