RoxanneB - From the different people on the forum, it sounds like each center (and possibly even each counselor) is different. My first time around I did have a counselor that pushed everything. I was on Phentatrim, Corti-Trim, MRC6, MSM, 7 keto DHEA, DIM, Natural Balance hormone cream, B6, B12, Guggul, Internal Cleanser, EFAs, Daily Vitamins, and Co Q10. This was in addition to the HNS (high nutrient supplements which is their protein drink)! I don't take that many now.
My recommendation is to be firm that they need to explain and prioritize the supplements for you so you can cross the bottom ones off of the list if you need/want to. There are some supplements that sound like they are great if you run into problems (like glucose for hunger/cravings) but you won't know if you will have those problems so you may want to wait and see on those.
It is a great program and you won't be disappointed. They have many supplements - the trick is figuring out which ones work for you. Good luck and keep us posted!! If you decide to join, we have an ongoing thread for each month that people doing the program post to. Hope to see you there!
