Compound Profile
Tirzepatide
Dual GIP/GLP-1 receptor agonist (prescription drug)
Tirzepatide is a dual GIP/GLP 1 receptor agonist, FDA approved as Mounjaro and Zepbound, showing the largest average weight loss effect of any approved obesity drug to date (up to ~22.
Use extra caution — Common side effects are nausea, diarrhea, vomiting, and constipation, dose dependent and most common during titration. Details

Prescription drug: approved-product and compounding rules are separate
Tirzepatide is used in FDA-approved prescription products including Mounjaro and Zepbound. FDA determined the tirzepatide injection shortage was resolved in December 2024, so shortage-based enforcement discretion for routine essentially-copy compounding has ended; 503A and 503B still operate under different statutory conditions.
- 503A patient-specific compounding is subject to conditions including restrictions on regularly or inordinate amounts making products that are essentially copies of commercially available drugs.
- FDA states tirzepatide is not currently on the 503B bulks list and is not on the drug-shortage list; FDA’s April 30, 2026 proposal to exclude it from the 503B bulks list is a proposal, not a final blanket rule.
- Compounded tirzepatide is not FDA-approved and does not automatically inherit the approved products’ quality or clinical evidence.
Regulatory status
2026 federal and state regulatory context
FDA approved and commercially available by prescription. As with semaglutide, the FDA has determined tirzepatide is no longer in shortage, curtailing 503B bulk compounding; compounded access now generally requires individualized physician documented clinical necessity. Not sold as a research peptide.
Regulatory changelog
- 2026: FDA shortage determination resolved for tirzepatide, winding down the compounded supply era; 503B bulk compounding no longer generally available absent individualized clinical justification.

Safety & Cautions
Common side effects are nausea, diarrhea, vomiting, and constipation, dose dependent and most common during titration. Less common but notable: gallbladder disease, rare pancreatitis, injection site reactions, and aspiration risk under anesthesia.
High caution
Caution level: High. Multiple caution categories apply, or the record uses avoid/contraindication language.
- Interaction-AwareMedication or interaction context is explicitly noted.
- Hormonal Activity ContextHormone-adjacent wording is present and should be interpreted carefully.
- Pregnancy/Breastfeeding CautionPregnancy or breastfeeding caution language is present.
Evidence-based safety
Caution when combined
Severity and certainty are shown separately. A high-priority caution can still be theoretical: these pairings are screened from shared contraindication mechanisms and are not automatically documented clinical interactions. Provenance identifies the source fields that produced each flag; it does not upgrade the certainty of the pairwise claim.

Treat this profile as unresolved until source review is complete.
Human clinical evidence: Not the primary signal
Mechanistic / preclinical: Mechanism mapped — Dual GIP And GLP 1 Receptor Agonism · Glucose Dependent Insulin Secretion · Central Appetite Regulation
Research maturity: Theoretical / mechanistic research — Mechanistic or unresolved evidence is kept separate from established human outcomes.
Safety boundary: Safety note available — Common side effects are nausea, diarrhea, vomiting, and constipation, dose dependent and most common during titration.
Confidence estimate based on the design quality and consistency of published clinical trials.
Tirzepatide has an evidence rating that is still under review.
How evidence grades work
Each grade reflects the strength and consistency of published human evidence — not marketing claims. Grades are based on study count, design quality, effect size, consistency, and recency.
- Strong
- Multiple RCTs, consistent direction, adequate effect size
- Moderate
- Some RCTs or consistent observational data in humans
- Preliminary / Mixed
- Animal or in-vitro only, or conflicting human data
- Traditional / Theoretical
- Traditional use only; no controlled human trials

Compound profile context
How to interpret Tirzepatide
Tirzepatide compound profile with evidence context, key research topics, source notes, safety context, and references presented in an evidence-first… Use this compound profile to understand mechanism, evidence quality, and practical safety context before comparing products or building a stack. A biochemical pathway connection can be useful for discovery, but it is not the same as proven benefit in humans.
When reviewing Tirzepatide, separate the active molecule from the product category around it. Dose form, absorption, extract standardization, medication interactions, and individual sensitivity can change the real-world risk-benefit picture.
For supplement planning, avoid combining multiple compounds with overlapping sedating, stimulating, serotonergic, blood-pressure, anticoagulant, or liver-metabolism effects unless a qualified clinician has reviewed the context.
