Identify the type of product on offer

The word peptide does not, by itself, establish whether a product is safe or lawful.
The Food and Drug Administration, called FDA, reviews medicines.
FDA has approved drug products containing semaglutide, sold as Ozempic and Wegovy, and products containing tirzepatide, sold as Mounjaro and Zepbound.
Ask for the medicine's full name and its form: a shot, a tablet or something else.
Made to order means a different path
Compounding means preparing medicine for a patient instead of supplying a finished factory product.
Before a compounded medicine reaches patients, FDA has not checked its safety, quality or how well it works.
A medicine made to order may be an option when an approved medicine cannot meet your medical need. The pharmacy must still follow the compounding rules.
For example, an allergy to a dye may call for a medicine without that dye; someone else may be unable to swallow the approved tablet.
Ask which need the change addresses for you, then ask what rule permits the pharmacy to prepare it. The compounding page below explains the ingredient and prescription checks.
Watch for 'for research use only' on an offer
FDA sent warning letters to sellers who promoted products for use in people even though the labels said 'for research use only'. Some labels instead said 'not for human consumption'. FDA called the products unapproved drugs sold in violation of federal law.
If an offer uses that wording, pause before buying it for treatment. Ask who will review your health problem and which pharmacy will fill a prescription.
