GLP-1, explained

Three questions that come up before anyone gets to a price. Answered from the same data the rest of the site runs on — 12 medications with their trial figures and verified prices, and 150 FDA warning letters — rather than from general knowledge, so the text moves when the data does.

• What a GLP-1 is, and what each one costs

  GLP-1 is a hormone your gut releases when you eat. The drugs named after it are copies that last longer, and the reason they work for weight is the same reason they were built for diabetes.

• GLP-1 vs GLP-3

  There is no GLP-3. No drug, no receptor by that name in this class, nothing approved or in trials under it. The search is real and rising fast, so it is worth saying plainly what people are usually reaching for.

• Is compounded semaglutide safe?

  Compounded semaglutide is not an FDA-approved product and has never been reviewed for safety, efficacy or quality. That is a statement about its legal status rather than a finding that it is dangerous, and the difference between those two things is the whole answer.

• The case for and against a GLP-1

  The honest version of this list is shorter than most and has numbers in it. What follows is drawn from the labels, the named trials and the prices verified on this site — not from a balance of opinions.
