Why does approval status matter?
FDA-approved drugs are reviewed for safety, effectiveness, quality, manufacturing, and labeling for their approved uses. An unapproved product has not completed that review. Compounded drugs are also not FDA approved.
Compounding may be medically appropriate for an individual patient in limited circumstances, but it is not a shortcut that makes an experimental or unapproved product equivalent to an approved drug.
What does the FDA say about popular peptide substances?
The FDA maintains a list of bulk substances for compounding that may present significant safety risks. The agency notes limited safety information, immune-response concerns, impurity and characterization problems, and reported serious adverse events for several substances commonly promoted online.
Retatrutide and cagrilintide cannot be used in compounding under federal law, according to current FDA guidance. FDA has also warned telehealth companies about marketing unapproved drugs with false or misleading claims.
Who can decide what is appropriate for your body?
In Texas, diagnosis and treatment are regulated medical acts. Prescription drugs require a valid prescriber and legitimate patient relationship. A fitness coach cannot replace that evaluation by asking a few questions on a sales call.
Eight questions to ask before moving forward
- What is the exact drug and approval status?
- Who is the licensed prescriber, and where are they licensed?
- How is a legitimate patient relationship established?
- Which pharmacy dispenses the product, and can its license be verified?
- Why is a compounded product medically necessary for this patient?
- What known risks, contraindications, and uncertainties apply?
- What evidence supports the exact promised benefit?
- How are adverse events, follow-up, storage, and dosing errors handled?
Marketing red flags
- “Research use only” products promoted for personal injection or treatment
- Guaranteed fat loss, healing, anti-aging, or muscle gain
- No named prescriber or dispensing pharmacy
- Claims that a compounded product is the same as an FDA-approved drug
- Dosing recommendations from an unlicensed salesperson
- Pressure to pay before a legitimate clinical evaluation
