I agree, the whole primary care system is sometimes worthless. I get way more information from my "integrative" anti aging doctor who handles my hormones than I do my primary care. Now, I pay him $300 (no insurance) for a 60 min appointment every six months, but then again, you get what you pay for.
I have tried the Super Beets as well. They don't affect my BP all that much, but can lead to some good erections! So, yes, I keep some of that powder around.
