Journal Article · Clinical Trial Protocol
Glucose and weight improved relative to placebo, with gastrointestinal events most frequent. The population, follow-up, and investigational formulation limit application beyond this trial.
This trial studied a controlled investigational formulation and selected adults with type 2 diabetes. It does not establish every long-term outcome or the identity and safety of retail research products.

Patient-derived tissue outside the body remains laboratory evidence. This does not establish cardiac benefit, arrhythmia risk, or clinical safety in people.

Why included: The compound is a named subject of the publication title.
Read the original study PMID 40613938 · PubMedOpen study summaryRetatrutide altered an experimental alcohol cue. That result does not establish reduced drinking or treatment of alcohol-use disorder in people, and the repeated semaglutide findings should not be assigned to retatrutide.
A rat discrimination task does not establish reduced drinking or treatment of alcohol use disorder in humans. The three drugs should not be treated as interchangeable.
Semaglutide, tirzepatide, and retatrutide attenuate the interoceptive effects of alcohol in male and female rats.

Why included: The compound is a named subject of the publication title.
Read the original study PMID 40699363 · PubMedOpen study summaryThe analysis used a subset of the parent trial with available scans. Weight loss included lean mass loss; this is not an independent trial or proof that muscle is preserved.
This shares the parent diabetes-trial population. Only 103 participants completed treatment and both DXA scans, limiting interpretation; it does not demonstrate muscle preservation or retail-product safety.

Read the original study PMID 41056349 · PubMedOpen study summaryProtein and lipid changes occurred together, while cell experiments suggested a glucagon-receptor mechanism. The clinical correlations do not alone prove that this mechanism caused the lipid changes.
These are secondary analyses of existing trials, not additional independent trials. Associations and cell experiments cannot prove clinical cardiovascular benefit.

Read the original study PMID 40094000 · PubMedOpen study summaryQuestionnaire changes concern perceptions and behaviors reported during an existing trial. Correlation with weight loss does not show which change caused the other.
Self-reported secondary endpoints come from an existing trial and do not independently establish the mechanism of weight loss.

Read the original study PMID 40464942 · PubMedOpen study summaryMost participants had normal baseline urine albumin, so absolute changes were modest. Changes in estimated filtration or urine markers do not establish prevention of kidney failure.
Most participants had normal baseline albumin excretion. These secondary analyses are not independent kidney-outcome trials.

Why included: The compound is a named subject of the publication title.
Read the original study PMID 40630318 · PubMedOpen study summaryLiver fat fell more in the retatrutide groups than with placebo. These are imaging outcomes from the parent trial's participants, not a separate confirmation of clinical liver benefit. Less liver fat does not by itself demonstrate less scarring or fewer liver-related complications.
This is a substudy of the obesity trial, not an independent replication. Liver-fat imaging does not establish effects on fibrosis, clinical liver outcomes, or long-term safety.

Why included: The compound is a named subject of the publication title.
Read the original study PMID 38858523 · PubMedOpen study summaryWeight changes were group averages, not predictions for an individual. Gastrointestinal adverse events were common and generally mild to moderate. Dose-related heart-rate increases peaked at 24 weeks and then declined; weight change alone does not describe the safety findings.
This selected 2023 trial concerns a controlled investigational formulation and population. It does not validate a retail research vial or establish its safety.

Why included: The compound is a named subject of the publication title.
Read the original study PMID 35985340 · PubMedOpen study summaryTwenty-nine participants discontinued early, and gastrointestinal problems were common. The short, small study was designed for early development rather than definitive efficacy or long-term safety.
