The starting point
What does peptide therapy mean?
Calling something a peptide describes the substance, without telling you which treatment is meant.
What does the word tell me?
Picture a short string of protein building blocks. That string is a peptide; insulin is a familiar example.
Does the word mean it works?
No. Have the clinician identify the proposed product and explain why they suggest it. The word peptide cannot settle either question.
Which medicines have approval?
U.S. medicine reviews fall to FDA (Food and Drug Administration).
For semaglutide, the brand names are Ozempic and Wegovy; tirzepatide’s are Mounjaro and Zepbound. Both medicines had approval from FDA for particular uses by September 26, 2026.
Wegovy includes weight-management uses; Ozempic includes blood-sugar control for adults with type 2 diabetes.
A product receives approval for stated uses; that approval does not extend to the whole peptide group.
Is a pharmacy-made version the same thing?
With compounding, a medicine is mixed for an order instead of supplied as an approved, ready-made drug.
Compounded drugs had no approval from FDA as of September 26, 2026. Before these drugs reach the market, FDA checks neither their quality nor their safety or effectiveness.
What about a research label?
A label reading “research use only” is not proof of medical approval.
As of September 26, 2026, no approved U.S. drug product existed for BPC-157 or retatrutide.
Ask whether the proposed product is a medicine meant for patient care, and how that status can be checked.
What can I ask about results?
Ask what studies show about this exact medicine for your health problem. Ask whether the studies used a shot, a pill, or another way of taking it. Then ask whether those results apply to the medicine you would receive.
