Compounded MOTS-c
MOTS-c was removed from the FDA's Category 2 bulk-substances list on April 15, 2026. The Pharmacy Compounding Advisory Committee (PCAC) reviewed compounding eligibility on 2026-07-23. Until that ruling is published and applied, 503A pharmacies cannot lawfully compound MOTS-c from bulk substances.
Pepticker primarily tracks research-use peptide pricing across registered research-chemical vendors. The 503A compounding-pharmacy channel is a different regulatory universe — it requires an individualized prescription, a licensed pharmacist, and a substance that is either FDA-approved or on the 503A bulk-substances list. The April 15, 2026 Category 2 removal disrupted that pipeline for the seven peptides on this directory, and PCAC is the body that decides whether it gets restored.
This page exists so that within 72 hours of a favorable PCAC ruling, a verified directory of US 503A pharmacies that actually compound MOTS-c can be published here. We do not pre-list pharmacies; the directory only goes live with verified, currently-active entries.
MOTS-c is a 16-residue mitochondrial-derived peptide encoded within the 12S rRNA gene. Published research describes effects on AMPK signaling, insulin sensitivity, and mitochondrial homeostasis in cell-culture and rodent models. A small number of early-phase human studies are underway in metabolic indications.
Live research-use vendor pricing for MOTS-c is tracked on the standard Pepticker PDP: MOTS-c price comparison.
MOTS-c was removed from FDA Category 2 on April 15, 2026 and is pending PCAC review on July 23-24, 2026. Compounding from bulk is not currently lawful at 503A pharmacies. Research-only purchase is presently the only legal route.
Favorable ruling pathway
A favorable PCAC vote returns MOTS-c to the 503A bulk-substances pipeline. State-licensed 503A compounding pharmacies that hold the appropriate non-sterile (or sterile-injectable, depending on dosage form) facility licensing would once again be able to dispense patient-specific prescriptions written by a licensed prescriber. In that scenario, this page will publish a verified directory of pharmacies that actually carry compounded MOTS-c, including state of license and any telehealth-clinic relationships. Listings will be sourced from state board of pharmacy records and direct verification — not vendor self-reporting.
Unfavorable ruling pathway
An unfavorable PCAC vote keeps MOTS-c off the 503A bulk-substances list. In that scenario the only legal channels in the United States remain (a) research-only purchase from registered research-chemical vendors and (b) any FDA-approved finished drug that happens to contain MOTS-c as an active ingredient (none currently exist for the peptides in this directory). This page would shift to a regulatory-history explainer rather than a pharmacy directory, and the research-use price comparison at /peptides/mots-c would remain the canonical Pepticker resource.
