That's true but in the real world, I wouldn't look to Mast as an AI. I always consider my AI dose based on all compounds that amortize. The thing nice about Mast is that I can run 150mg/wk of Test (TRT dose) and run 100mg/wk of Mast and I have the Test value of 250mg/wk and I have only 150mg/wk of Test amortizing so I don't need to run an AI.
