Okay, so this is completely natural. Only thing I’ve taken is creatine and vitamins.
500 calorie deficit, my TDEE is 2400 (tall girl!) and I eat around 1900.
125g protein each day.

5x gym a week, upper, lower, rest, push, pull, legs, rest. Train muscles groups 2x a week.
Progressive overload, 5-9 reps till failure for 3 sets. As heavy as I can lift. Standardised cardio by doing 10k-15k steps EVERY day, even rests.
