What it is

Retatrutide is a peptide in the incretin & amylin analogs class (GIP, GLP-1 and glucagon receptor triple agonist). Europe PMC indexes 197 publications naming it or a listed alias in a title or abstract, including 7 randomized controlled trials and 9 clinical trials of any design, as of . The strongest evidence tier in that literature is human clinical trials.

This page reports what those studies state, sentence by sentence, with each statement tied to its source and labeled by the kind of evidence it is. It does not recommend use, and it does not translate study doses into anything personal.

What the evidence level means

Publication counts show what is indexed, not how strong the evidence is. The ledger below separates human clinical records from preclinical, analytical, and in-vitro work.

What the evidence shows

One row per primary study in this record's ledger. Fields are read from each paper's indexing and abstract. "Analytical method" marks papers about detecting or measuring the compound rather than about its effects.

Reconstitution mathematics

Lyophilised peptide is supplied as a mass in a vial and dissolved in a stated volume of diluent. Two figures follow from that and nothing else:

  • Concentration = mass in vial ÷ diluent volume. A 5 mg vial in 2 mL is 2.5 mg/mL, or 2,500 mcg/mL.
  • Volume for a given mass = that mass ÷ concentration. 250 mcg at 2,500 mcg/mL is 0.1 mL. On a U-100 insulin syringe, where 1 mL is 100 units, that is 10 units.

Study doses on this page are quoted as published, in the units the authors used. Converting between mcg, mg and IU, or between a mass and a syringe volume, is arithmetic; deciding a mass is not, and this page does not do it. The reconstitution calculator performs the conversion with the formula shown.

Reading a certificate of analysis

A certificate of analysis is a laboratory report on one batch. Reading it means checking four things in order.

  1. Identity. Mass spectrometry should report an observed molecular mass matching the peptide's theoretical mass within the instrument's stated tolerance. A certificate with no mass spectrometry, or one that lists only the expected value, has not confirmed identity.
  2. Purity. HPLC purity is the area of the main peak as a share of all peaks, at a stated wavelength. It says nothing about what the other peaks are, and it is not a measure of quantity.
  3. Quantity. Net peptide content, by amino acid analysis or UV, is the fraction of the vial's mass that is peptide rather than counter-ions and water. A 5 mg vial at 80% net content holds 4 mg of peptide, and every concentration figure above changes accordingly.
  4. Provenance. The batch number on the certificate should match the vial, the laboratory should be named and independent of the seller, and the test date should be recent.

This page rates no supplier and links to none. It describes how to read the document.

Equipment described in studies

Published human studies of injectable peptides report the same small set of materials: single-use insulin syringes with fixed needles, most often U-100 with 29 to 31 gauge needles; bacteriostatic water or sterile water for injection as diluent, with the choice stated in the methods; alcohol swabs; and refrigerated storage of reconstituted solution. Animal studies more often report intraperitoneal or intragastric administration and state the vehicle used. Where a study in this record's ledger names its materials or vehicle, that sentence appears under storage or routes above; where it does not, nothing is assumed here.

Same class in the registry: Cagrilintide, Semaglutide, Survodutide, Tirzepatide. Each row shows what that compound's own record states; nothing is inferred across rows. Head-to-head evidence, where any exists, is on the comparison pages: Retatrutide vs Tirzepatide, Semaglutide vs Retatrutide.

Open questions and limitations

What is genuinely unknown, stated plainly. A missing field is not evidence that the outcome is safe, effective, or established.

  • No study in this record's ledger reports weight-normalized doses for Retatrutide.
  • No study in this record's ledger reports dose-escalation schedules for Retatrutide.
  • No study in this record's ledger reports interactions with other agents for Retatrutide.

Questions people ask

Has Retatrutide been tested in humans?

Yes. Europe PMC indexes 9 clinical trials and 7 randomized controlled trials naming Retatrutide or a listed alias in the title or abstract. The evidence table above lists the ones in this record's ledger with their design and sample size; check the study name, since an alias can refer to a different formulation of the same molecule.

What kind of evidence exists for Retatrutide?

The strongest tier is human clinical trial: human clinical trials. Every claim on this page carries its own tier, because a compound with one human trial and forty animal studies is described by both facts, not the better one.

Is Retatrutide an approved medicine?

ChEMBL records CHEMBL5095485 at maximum clinical phase 3, with no approval recorded. Approval status differs by jurisdiction and is pending human review on this record.

Which species has Retatrutide been studied in?

Studies in this record's ledger report work in: Humans, Mice, Rats. Findings in one species do not transfer to another, and weight-normalized doses in particular do not scale linearly between them.
