In December 2025 Eli Lilly published the first phase 3 data (TRIUMPH-4), followed in May 2026 by TRIUMPH-1. &#8220;GLP-3&#8221; is neither a receptor nor an official substance name but a community shorthand for exactly this third generation of incretin agonists. For laboratories this means: the molecule is characterised as well as hardly any other research peptide \u2013 which makes it all the more important that the material used is verified batch by batch via HPLC and mass spectrometry.<\/p>\n<h2>What is retatrutide \u2013 and why does everyone say &#8220;GLP-3&#8221;?<\/h2>\n<p>Retatrutide (development code LY3437943) is a synthetic peptide that activates three receptors at once: the GLP-1 receptor (like semaglutide), the GIP receptor (as tirzepatide does in addition) and the glucagon receptor. This third component sets it apart from every incretin drug approved so far. Because semaglutide (&#8220;GLP-1&#8221;) and tirzepatide (called &#8220;GLP-2&#8221; in the community) are now followed by a substance with a third receptor target, the short form <strong>GLP-3<\/strong> has established itself as a search term and everyday label.<\/p>\n<p>Scientifically this is imprecise: GLP-2 is a distinct, real gut hormone, and a &#8220;GLP-3 receptor&#8221; does not exist. Anyone who wants to stay accurate speaks of a <em>GIP\/GLP-1\/glucagon triple agonist<\/em>. We have broken down the terminology in detail in our <a href=\"https:\/\/peptelia.com\/en\/library\/glp-nomenclature\/\">GLP nomenclature overview<\/a>.<\/p>\n<h2>TRIUMPH-4 (December 2025): the first phase 3 trial<\/h2>\n<p>The first completed phase 3 trial of the TRIUMPH programme was TRIUMPH-4 (NCT05931367). It enrolled 445 people with obesity and knee osteoarthritis, with a mean BMI of 40.4 kg\/m\u00b2. The trial was placebo-controlled; details of the study design are given in the primary source.<\/p>\n<ul>\n<li><strong>Research question:<\/strong> body weight and knee pain (WOMAC pain scale) were examined as endpoints; results are given in the original publication and the manufacturer&#8217;s press release.<\/li>\n<li><strong>Study design:<\/strong> randomised and placebo-controlled over 68 weeks.<\/li>\n<li><strong>Context:<\/strong> safety and tolerability data from human trials are given in the primary source and are not reproduced here.<\/li>\n<\/ul>\n<h2>TRIUMPH-1 (May 2026): the large obesity trial<\/h2>\n<p>On 21 May 2026 the data from TRIUMPH-1 followed \u2013 the largest trial in the programme to date, with 2,339 participants over 80 weeks. For design and results see the original publication and the manufacturer&#8217;s press release; dose and efficacy figures are not reproduced here.<\/p>\n<p>Results from TRIUMPH-2 and TRIUMPH-3 (type 2 diabetes, cardiovascular endpoints) are still pending; to date there is no marketing authorisation.<\/p>\n<h2>What the trials do not say<\/h2>\n<p>Two points are regularly overlooked in forums. First: all figures come from controlled trials with clinical titration, supervision and selection criteria \u2013 they describe a medicinal product in development, not a research peptide from a vial. Second: retatrutide is not approved in the EU. As a research substance it may only be sourced and used for in-vitro and documented laboratory purposes \u2013 not for use in humans. This distinction is not a formality but the legal framework we explain in <a href=\"https:\/\/peptelia.com\/peptide-legal-deutschland\/\">Are peptides legal in Germany?<\/a> (in German).<\/p>\n<h2>What laboratories should check when sourcing retatrutide<\/h2>\n<p>Precisely because the molecule is studied so intensively, it appears in many shops \u2013 with very different documentation. Four checkpoints before a batch goes into a protocol:<\/p>\n<ol>\n<li><strong>Batch-specific COA.<\/strong> The certificate of analysis must carry the lot number of the vial, show an HPLC chromatogram and confirm identity by mass spectrometry. A purity percentage on a letterhead is not evidence. How to check a COA in five minutes is explained in the <a href=\"https:\/\/peptelia.com\/en\/your-coa-guide\/\">COA guide<\/a>.<\/li>\n<li><strong>Net peptide content instead of HPLC purity.<\/strong> 99 % HPLC purity does not mean 99 % peptide in the vial \u2013 counterions (TFA) and residual water have to be deducted. For concentration calculations the net content is what counts; the calculation methods are in our article on <a href=\"https:\/\/peptelia.com\/en\/retatrutide-dosing-research-protocol\/\">calculating retatrutide concentrations in research protocols<\/a>.<\/li>\n<li><strong>Suitable nominal amount.<\/strong> Anyone planning a series of experiments should choose the nominal amount so that no batch changes in the middle of the series. Pept\u00e9lia stocks retatrutide GLP-3 in <strong>5, 10, 15 and 20 mg<\/strong>, each as packs of 1, 3, 5 and 10 from the same batch. The <a href=\"https:\/\/peptelia.com\/en\/retatrutide-price-comparison\/\">price and quantity overview<\/a> compares the price per milligram across all sizes.<\/li>\n<li><strong>Storage and reconstitution.<\/strong> Lyophilised: cool, dry and dark; reconstituted only with bacteriostatic water and without shaking. Pept\u00e9lia includes BAC water with every order.
