I simply wouldn't trust any online pharmacy that wasn't backed by a well known brick and mortar. Way too many scams out there.
Have you tried altering your diet to control cholesterol? I know it doesn't work for everyone, but it did work me, and quite well. Went from over 300 to around 150 in less than a year with diet and exercise. Cheaper than meds.
Again, I realize it doesn't work for everyone!
