I began with 1mg in week 1, then 2mg weekly, split. Biggest side effect is a higher heart rate, about +10bpm at 2mg. I'd like 3mg at week 5 but I'm not sure I will. Loss is small and appetite is heavily suppressed on this dose, but I hit my protein and train 3 days weekly. I'd like to do more, yet the elevated heart rate and low overnight HRV have wrecked my recovery, so my tracking app pulls me off the gym on rough days, and there've been plenty by recovery score. Even so, today is day 21, 9 pounds gone, and my body scan shows 3 pounds of muscle gained.
