A step in the right direction. So you've piqued my interest.
My comments, FWIW:
If you saw a doctor and have a diagnosed hormone imbalance, what is his/her recommended course of treatment? I doubt it includes OTC hormone supplements. Maybe it does. But you need to tell us what your doctor said before we can give advice.
You need to get your diet in check. I get that you want to start keto, but why? Just for fat loss? You are young. I know that when I was your age (I'm 34 now), there is no way I could pull off a keto diet. Do you make all of your own meals? Do you go out with friends? You need to figure out a nutrition plan that can fit your lifestyle. Maybe keto can, but I doubt it.
So figure out your nutrition. I'm by no means an expert. But, what's your TDEE? I'd start there. Then figure out the daily cals/macros that you want to hit for your goal (cutting) and stick with a nutrition plan for at least 2-3 months . If you're not getting good results, tweak your cals/macros. Also, if you get your nutrition on point, you don't need to focus on intra supplements right now.
Simplify your training. Again, I'm not an expert. But every program you mention (DC, PHAT, Meadows programs, etc.) is for intermediate/advanced lifters. Be real with yourself. You are not at that level. You can make much better (and faster) progress with a more basic routine.
Stop focusing on supplements. Nutrition and training first. Except for the Morphogen Alphagen ... but only because I know the owner of Morphogen
