What's with these websites where you can order prescription meds? Are they legal

They are legal, even though they are seriously pushing the envelope. You won't get in trouble. They allow you to buy meds without going to a doctor, just like you can do in most of the world, simply by going to a pharmacy. If you do this, you need to take more responsibility for your own health. Read the literature. Understand the contraindications. If you don't understand anything you have read, then do see a doctor. Do take care to use these services responsibly. Thank you.
