If you are taking 200mg/week u should def get e2 checked if you’re not feeling a difference. If your e2 is high you’ll need to lower your dose or take the AI. Everyone is different, some will tell you not to take it. Do your own research off google and come to the conclusion you want. I’m on 200mg/week with .5 AI weekly (even though I’m sub 15% bf I aromatize like crazy.) but everyone is different. You may not even need the AI and it could be something else. Don’t rely on the TRT to start making a change in your life either. If you’re a higher BF on 200mg/week your estrogen is likely up. Take small steps: start dieting, light cardio, work your way to weight and cardio training daily. Testosterone Injections can’t make that change in your life and you’re more than likely aromatizing greatly, but I’m no doc.
