What's up guys? When it comes to which A.I. to use for which situation, I'm not afraid to admit that I could use some further knowledge regarding which one is best suitable for which situation. I'm maily talking about Anastrazole, Exemestane, and Letrozole. Now, I've read so much conflicting information on these three A.I.'s, that it's driving me crazy! There are certain things that I read, like out of the three, Exemestane is better for heart and cardiovascular health, Letrozole is good if you start to notice any symptoms of gyno, and lots of conflicting information about the three. I usually use Anastrazole when an A.I. is needed, and like I said, I read that if I begin to notice any symptoms of gyno, I should switch to Letrozole, which thankfully I haven't had to do yet. But what I have done after noticing sore nipples while on Anastrazole, is switch to tamoxifen for a few days, and then go back to Anastrazole. Also, when I feel like I may need a stronger A.I., then sometimes I'll use Exemestane. What I'm trying to find out is which out of the three A.I.'s is the healthiest for the heart in particular, and would the best thing to do when beginning use of an A.I., be to start with either Anastrazole or Exemestane, and if you begin to notice any gyno symptoms, swith to Letrozole? There's so much conflicting information about these three A.I.'s, that it really starts to get confusing. So also, what steroid or steroid combination would call for which A.I.? Any helpful information regarding the use of Anastrazole, Exemestane, and Letrozole, and for which types of steroids, would be greatly appreciated! And, is Anastrazole the best all around A.I.? Thanks!
