Maximum clinical dose is 15mg/week. The dr. told me to start 2.5mg then 2 or 4 weeks later move to 5mg, then 2 or 4 week later go to 7.5 mg. I kept going, 10mg then 12.5mg a week until I hit goal. That's below max clinical dose. 1 to 2 mg isn't going to do anything. Even now during. A semi bulk I am still on 4 mg/week. I tried 5mg/week but had trouble hitting my 3000 calorie a day goal.
Tirz helped me maintain a 1200 calorie a day diet for 12 months. 200+gms of protein a day. Went from 43% to 20% to 12% bf.
