FDA peptide categories

What "FDA Category 1" actually means for the peptides you're asking about.

The peptide conversation online is noisier than it needs to be. The FDA sorts bulk substances into three categories that decide whether a pharmacy can compound them. Here's the plain version, and why "Category 1" is not the same as "FDA-approved."

The three tiers

CategoryWhat it meansCompoundable?
Category 1Sufficient safety information to compound under interim policy.Yes, with a patient-specific prescription and clinical oversight.
Category 2Significant safety risk identified.No, not compoundable.
Category 3Insufficient data to evaluate.No, not compoundable.
Category 1 ≠ FDA approval

Category 1 means a substance can be compounded under interim policy with clinical oversight. It does not mean the substance went through FDA drug approval. Compounded medications are not FDA-evaluated for safety, efficacy, or quality.

What's compoundable now

  • Sermorelin, 503A eligible (Category 1), available today under clinician supervision.
  • Gonadorelin, 503A eligible (Category 1), available as a hormone-support adjunct.
  • GLP-1 (semaglutide / tirzepatide), a separate 503A / shortage-exception pathway, distinct from Category 1. Confirm current eligibility with the pharmacy.

The federal requirements

  • A patient-specific prescription from a licensed clinician of record.
  • 503A or 503B sourcing, a licensed compounding pharmacy, not a research-chemical vendor.
  • USP 797 sterile-compounding standards.
  • FDA-registered API with a valid Certificate of Analysis (COA).
Questions, answered

The honest answers.


Most compounded peptides are not FDA-approved. Compounded medications are not evaluated or approved by the FDA for safety, efficacy, or quality. A few molecules have an approved branded form for a specific use; we label which is which plainly.
No. BPC-157 is one of seven peptides under FDA review (PCAC, July 23–24, 2026) and has not been reclassified. It is not available to compound today, being under review is not the same as being legal to compound or available.
