I've tried thyro-drive to help lose my winter weight. I'm in my mid 40's, and it was taking longer than usual. I added Goddess, and L-Carnitine to the mix and my weight came off quickly with my diet/exercise regimen. I placed a second order, the day before the 4th of July tee giveaway :( for Thyro and GDA. The products are great, but the customer service is what made me return. My questions were answered promptly, and they add a hand written note in the orders. That leads me to believe they care about their customers!
