Saggy skin

I am very new to biohacking and I am soon to buy Reta. I am 23m 230lbs. My issue was binge drinking then I quit drinking and started binge eating. Before all of this I was 185ish and was very toned. I have a belly now and my ol lady says my boobs are bigger than hers lmao. I am pretty active, I work out atleast 2 times (weight train) a week and on top of that practice/race motocross 2-3 times a week. Which the motocross is mostly endurance and sweat. My issue here is strictly eating! I can’t put the bed time cookies down!

My huge worry here is loose skin. Will there be much to worry about along as I take it slow, ie. 1mg a week?
