Are peptides legal in Michigan?

Gray area

Peptides sit in a gray zone in Michigan: FDA-approved peptide drugs are legal with a prescription and a licensed Michigan pharmacy may compound patient-specific preparations, but research-use-only peptides are unlawful for human use and BPC-157 is not an eligible compounding substance.

Legal status overview

Peptides sit in a gray zone in Michigan. FDA-approved peptide medicines such as Ozempic® (semaglutide) and Mounjaro® (tirzepatide) are legal when prescribed by a licensed physician, and a Michigan-licensed 503A or 503B pharmacy may prepare compounds, though those compounds are not FDA-approved, not a generic, and not evaluated by the FDA. The Michigan Board of Pharmacy, within LARA, licenses and inspects compounding pharmacies and requires proof of USP-compliant sterile compounding for injectable peptides. Peptides sold as research chemicals for human use are unapproved drugs and are unlawful, and BPC-157 remains outside the eligible compounding lists.

Key points

  • FDA-approved peptide drugs such as Ozempic® (semaglutide) and Mounjaro® (tirzepatide) are legal in Michigan when prescribed by a licensed physician. [5]
  • The Michigan Board of Pharmacy, part of LARA, licenses and inspects compounding pharmacies and requires in-state and out-of-state sterile compounders to document current accreditation and USP-compliant inspection reports. [2]
  • Compounded peptides are legal only when prescribed by a licensed physician and prepared by a Michigan-licensed 503A or 503B pharmacy, and those compounds are not FDA-approved, not a generic, and not evaluated by the FDA. [6]
  • Research peptides are not legal for human consumption in Michigan, and selling such products with implied human use violates both federal and state law. [5]
  • Large-scale, essentially-a-copy GLP-1 compounding ended after the FDA declared the shortages resolved, with tirzepatide off the shortage list in October 2024 and semaglutide in February 2025, leaving only documented patient-specific compounding. [4]
  • BPC-157 was removed from the FDA Category 2 bulk-substances list in April 2026 but was not added to Category 1, so it is not an eligible bulk substance for Section 503A compounding. [7]
  • The Board of Pharmacy holds statutory authority to inspect pharmacy practice and to discipline licensees who harm public health and safety. [1]
  • Michigan adopted the 2023 revisions of USP Chapters 795 and 797, including a two-step inspection process for in-state pharmacies that compound sterile products. [2]

Compound-by-compound status

BPC-157
Restricted
Unapproved new drug. Removed from FDA Category 2 in April 2026 but not placed in Category 1, so it is not eligible for Section 503A compounding. Not FDA-approved, not a generic, and not evaluated by the FDA.
GLP-1 class (semaglutide, tirzepatide)
Legal
Branded FDA-approved products such as Ozempic® (semaglutide) and Mounjaro® (tirzepatide) are legal with a prescription. Compounded GLP-1 preparations are now limited to documented patient-specific need and are not FDA-approved, not a generic, and not evaluated by the FDA.
TB-500 (thymosin beta-4)
Illegal
Unapproved new drug with no FDA-approved human indication. Selling or using it for human consumption, including as a research chemical, is unlawful under state and federal law.
Growth hormone / somatropin
Legal
A prescription drug legal only for FDA-approved indications under a valid prescription and prepared or dispensed by a licensed pharmacy. Federal law separately restricts human growth hormone distribution outside approved uses.

Frequently asked questions

Are peptides legal in Michigan?

FDA-approved peptide drugs are legal with a prescription, and licensed Michigan pharmacies may compound patient-specific preparations. Peptides sold as research chemicals for human use are unlawful. This is information, not medical advice.

Can I get compounded semaglutide or tirzepatide in Michigan?

Only through a Michigan-licensed 503A or 503B pharmacy for a documented patient-specific need, because the FDA has ended the shortage-based compounding allowance. Compounded versions are not FDA-approved, not a generic, and not evaluated by the FDA.

Is BPC-157 legal to use in Michigan?

BPC-157 is an unapproved drug and is not on the FDA list of substances eligible for compounding, so it is not cleared for clinical use despite its April 2026 removal from Category 2.

What does the Michigan Board of Pharmacy require for sterile peptide compounding?

Pharmacies that compound or ship sterile products into Michigan must document current accreditation and a recent USP-compliant inspection, and in-state sterile compounders face a two-step inspection process.

Are research-use-only peptides allowed for personal use?

No. Products labeled research-use-only are unapproved drugs, and marketing or using them for human consumption violates state and federal law.
