Getting started
Michigan peptide therapy, translated.
The phrase sounds like one branch of medicine. It is really a loose label that can cover very different products. Knowing which kind is in front of you clears up most of the confusion.
One word. Three lanes.
Peptide
A description, not a promise
Peptides are brief runs of amino acids, the raw material every protein uses. Insulin is one; the hormone in a weight-loss shot is another. Some are medicines. Some are lab chemicals. The word by itself says nothing about approval, quality or fit for a person.
That is why a search for peptide therapy can turn up weight-loss shots, medicines a pharmacy mixes to order, and bottles marked “for research” that are sold outside medical care. So skip “Is it a peptide?” and ask “Which product, exactly, am I looking at?”
The three lanes
Same search. Different rules.
- Approved medicine. You can find FDA-approved versions of semaglutide (Ozempic, Wegovy) and of tirzepatide (Mounjaro, Zepbound), as of September 2026.
- Compounded medicine. A pharmacist or doctor prepares it for a patient rather than dispensing a finished drug-company product.
- Research-only chemical. Something sold online for human use under a “for research use only” label is not, as of September 2026, a lawful way to get treatment.
Prescription
A decision tied to a real person
A prescription follows an assessment by someone who is allowed to prescribe. On this guide, “clinician” means the medical person who treats you, be it a doctor, a nurse or a physician assistant. The useful signs are simple: that person has a name, asks enough to understand the situation, explains what happens next, and sends the prescription to a named pharmacy.
A product menu can make care look like shopping. Care begins with a health question, not with choosing a vial from a shelf.
