I live in a small town, and tried to find stuff... drove to a larger city... checked at Walgreens.... I got tired of looking, and just didn't want to try and consume all the requirements... so i just went to tespo... and ordered bariatric & hair & nails. I"ve been very happy with them, and know that I'm getting the right amount. It probably is more expensive, but i have so many other things going on in my life with job, family... it makes my life simple.
