Type one
FDA-approved medicine
Ozempic and Wegovy were FDA-approved semaglutide medicines as of September 2026. As of that date, approval belongs to a specific medicine and use, not to every item with a similar name.
Identify the kind of medicine
The first page of the book peptide clinic guide
Before comparing claims, find out which of three very different kinds of medicine or chemical is in front of you.
The first question
“They call it a peptide. Does that mean it is approved?”
As of September 2026, “peptide” tells you what a substance is made from, not whether it is an FDA-approved medicine, a lawfully made-to-order medicine, or an unapproved chemical.
Keep these apart
Three types, three different checks
The kind of medicine or chemical matters more than the glowing claims around it.
Type two
Compounded medicine
A medicine made to order could be legal as of September 2026, but it was not FDA-approved and did not receive an FDA check before sale.
Type three
Research-labelled chemical
An online chemical labelled “for research use only” was not a medicine as of September 2026, and ordering it to inject did not offer a legal route to treatment.
