I am 49 years old, I definitely notice a huge difference in my sleep, my eating disorders, easy weight loss, but most importantly, after pellet, my hormones are SO UNDER CONTROL. I fell better and younger. This might be Expensive for some. Be prepared. I do not take any of the supplements I purchased. So be wise as what to buy after consultation. It can go UPTO the low $2000. We are worth it all!

I also never drank the shakes they offer, I HAVE MY PREFER SHAKES, mine are a whole lot less carbs no sugar and high in protein. I did follow their diet though. Since Mid July, 2020 I have lost 30 lbs. God bless you!

Dr. Sun is very knowledgeable and a lovely person. I came to her after being with another hormone doctor who retired, and so i knew exactly what worked for me. She was able to continue to do what i had before but also work with some other things that came up.
