Start with the product, not the promise. The exact medicine and the way it is made tell you more than a broad phrase like “peptide therapy.”
Peptides are short strings of the same units that make up proteins. Insulin is one example, and so is the hormone that some weight-loss shots are modeled on. As of September 2026, knowing something is a peptide says nothing about whether the product is approved, safe, or lawful.
Source ATwo of these drugs have FDA-approved versions on the US market as of September 2026: semaglutide (the drug behind Ozempic and Wegovy) and tirzepatide (the drug behind Mounjaro and Zepbound).
As of September 2026, an approval covers one exact product, in one form, for the conditions named on its label. Form means a pen, a vial, or a tablet. The approval does not stretch to every offer that uses the same ingredient.
Source BCompounding means a pharmacist, a doctor, or a larger registered compounding business mixes the medicine to order, instead of supplying a finished product from a drug company. FDA calls those larger businesses outsourcing facilities.
No compounded medicine is approved as of September 2026, which means FDA has done no pre-sale check of its safety, effect, or quality.
Source CAs of September 2026, a chemical sold as “research use only” is not a lawful treatment path when it is really offered for human injection.
Source DExpect to explain your goal, health history, current medicines, and past problems. The prescriber, meaning the doctor or nurse who writes the prescription, may ask more questions before deciding whether any treatment suits you.
Good care leaves space for your questions. An online questionnaire can start the conversation, but it cannot replace every part of one.
As of September 2026, state medical board policy on online visits says the prescriber must be licensed, or have similar permission, in the state where you are.
So ask which states the prescriber may treat people in, and make sure yours is one of them.
Source EFederal law sets no blanket requirement for lab tests before each prescription as of September 2026; state rules, and what the prescriber needs to know about you, still count.
Source FThe prescriber is expected to arrange the test, or send you to a lab or another doctor who can do it.
Ask what is needed now, what may be needed later, and what each piece could cost.
