Doctor red flag?

I've been on an impossible weight loss "journey" being on semaglutide for 1.5 years and now Tirzipatide for the last 4 months and still barely seeing results. I'm eating less, moving more, eating healthy according to the PCOS experts. I'm almost always in a calorie deficit. I went to a Horomone and Weight Loss specialist 4 months ago who diagnosed the PCOS and put me on Tirz plus Cortisol, Vitimin D, and DHEA supplements. I've made radical lifestyle changes since and added Metformin and Phentermine a month ago. I got a second opinion from an OBGYN last week since I'm still not seeing great results. She asked about the DHEA supplements and said those could be counteracting some of the positive things Ive been doing. She ordered comprehensive horomone bloodwork. It turns out, my DHEA is through the roof high. Why would a Horomone and Weight Loss Specialist put me on DHEA supplements when that seems like a major driver for certain types of PCOS? Could going off the DHEA supplements finally help treat my insulin resistance? After lots of my own research, I asked the Hormone Specialist how DHEA was helping and she said it can help balance the imbalance. Is that nuts? is she a quack? Her clinic is all out of pocket so I'm hoping to switch to this OBGYN who is in network but I did appreciate that the Horomone Doctor diagnosed the PCOS in the first place and she's who I get the stupidly expensive Tirzipatide from. Thanks for any insights you have!
