Aromatase Inhibitors like Letrozole ect.

I've been researching aromatase inhibitors, especially letrozole, and I'm trying to figure out which AI is generally considered the best to pair with GH, but I've come across a lot of conflicting information. Is letrozole the best option, or would you choose something like anastrozole or exemestane instead? Any insights or research you've found would be greatly appreciated.

Thanks in advance! ❤️
