Hey, so i have read that :

"There are two types of AI’s:

• Type 1 (irreversible steroidal inhibitors)
• Type 2 (non-steroidal inhibitors)

Type 1 inhibitors form a permanent and deactivating bond with the aromatase enzyme, so it never lets go even when the drug is discontinued or its active life expires. Type 2 inhibitors inhibit the synthesis of estrogen via reversible competition for the aromatase enzyme, which means that it binds reversibly. An example of an irreversible inhibitor would be Aromasin (exemestane). Examples of reversible inhibitors, or Type 2, would be Letrozole (Femara) or Anastrozole (Arimidex)."

I don't want to crash my Estrogen levels and I feel like Aromasin would do that.

We can also see that:

"Arimidex/Anastrozole Decreases IGF-1 18% while Aromasin/Exemestane Increases IGF-1 28%. Aromasin is also known to decrease estrogen between 90-95% while boosting Endogenous Testosterone by about 60%"

So I don't know what to choose anymore because I was going to take Arimidex but apparently it decrease IGF-1, but i'm taking IGF-1 LR3 anyway.

Btw, my current stack is:
6iu's of HGH ED
IGF-1 LR3 100mcg ED
(and i need to add an AI to my stack)

I just turned 17 two months ago, i'm 5'11 (1,80 cm), and i have already grown 2 cm in 1 month.
With that stack I want to hit 6'2 (188cm).
If you want to see where I got this stack you should check out this thread:

So for the sole purpose of slowing the fusion of my growth plates, what's better between Aromasin, Arimidex or Letrozole ?
