Did you already make a thread about this?
Diet
First things first. Up the protein to 250. If you cannot get it in, stop the fucking trizepatide.
Second, tomorrow, increase your carbs to 250. Try to keep those fats where they are or even lower by experimenting with substituting foods.
Cardio
Third, Bump Up the intensity on the cardio. What is your heart rate? If you do not know your heart rate, figure out how to do some cardio where you can track heart rate and maybe even calories burned.
Bodybuilding with Weights
You are weight training, so what does
leg day look like? Just look at your log and tell us weight, sets, reps.
Also, are you progressing every workout - adding reps, sets, or weight or something every time? At 16% body fat you should not be losing any strength in the gym, especially while also on 600mg of steroids.
Keep it Steady for A Week
If your weight remains stalled out for the next seven days, then it will be time to make some adjustments, but just try out the above for now.
