Best MOTS-c Providers in 2026 — Ranked & Reviewed
MOTS-c is a mitochondrial-derived peptide studied in mice as a metabolic regulator and “exercise mimetic.” We want to be direct about this one: no human randomized trial has ever tested MOTS-c as a weight-loss treatment, and it has no FDA approval for any use — see our full evidence review for the details. On top of the evidence gap, no compounding pharmacy can currently sell it lawfully either. See below for the current status.

Why there’s no ranking here yet
On July 23, 2026, the FDA's Pharmacy Compounding Advisory Committee (PCAC) voted to recommend adding MOTS-c to the Section 503A Bulk Drug Substances List. That vote is a recommendation only; the FDA and HHS still need to formally act on it before any compounding pharmacy can lawfully sell MOTS-c. Even once that happens, the underlying evidence gap for weight loss specifically won't have changed — see our full evidence review. We audited our catalog and could not confirm a provider currently selling MOTS-c in full compliance, so we're not ranking any until that changes.
We’d rather show nothing than list a provider who can’t legally sell this yet. We’re tracking the FDA’s decision and will rank compliant providers here the moment one exists.
How we rank & what counts as “legit”
Every provider in this ranking is scored against our published six-factor rubric[1] — value, effectiveness, user experience, trust & safety, accessibility, and support.
Brand-name Wegovy, Zepbound, Ozempic, and Mounjaro are separately FDA-approved under their own NDA numbers[4][5]. Published Phase 3 efficacy for semaglutide 2.4 mg (~14.9% mean weight loss over 68 weeks) comes from the STEP 1 trial[6], and for tirzepatide (~20.9% at the 15 mg dose over 72 weeks) from SURMOUNT-1[7]; the SURMOUNT-5 head-to-head published in 2025 compared the two directly[8].
Insurance coverage for anti-obesity medications varies widely by state Medicaid program and commercial plan[9][10]. Compounded and brand-name GLP-1s are generally FSA/HSA eligible with a prescription under IRS Publication 502[11].
