The sequence is derived from native GIP and carries a lipidated side chain that the literature associates with albumin binding and an extended half-life. As the first widely published representative of the triple agonist class, Retatrutide serves in basic research as a reference compound for studying simultaneously activated incretin and glucagon signalling pathways.<\/p>\n<ul>\n<li>Nominal amount: 15 mg<\/li>\n<li>Batch-specific certificate of analysis (COA)<\/li>\n<li>Documented assignment of product and batch<\/li>\n<li>Analytical data on the stated identity and purity according to the COA<\/li>\n<\/ul>\n<p>The decisive reference is always the COA of the batch actually shipped, not a general purity figure quoted on a product page.<\/p>\n<figure class=\"wp-block-video peptelia-video\" style=\"margin:2em 0;\"><video controls preload=\"metadata\" playsinline style=\"width:100%;max-width:100%;height:auto;aspect-ratio:16\/9;border-radius:8px;\" title=\"Retatrutide GLP-3 \u2013 product video\"><source src=\"https:\/\/peptelia.com\/wp-content\/uploads\/2026\/10\/davinci__video1___image1_ein_video_nach_dem_vorbild_von_vi.mp4\" type=\"video\/mp4\">Your browser does not support HTML5 video.<\/video><\/figure>\n<h2>Product details<\/h2>\n<p>Short molecular profile:<\/p>\n<ul>\n<li>Class: synthetic, lipidated peptide based on GIP<\/li>\n<li>Mechanism described in the literature: agonism at the GIP, GLP-1 and glucagon receptors<\/li>\n<li>Typical research fields: receptor pharmacology, incretin and glucagon signalling pathways, energy metabolism in cell and animal models<\/li>\n<\/ul>\n<p>In research models, Retatrutide is examined with regard to the combined activation of GIP, GLP-1 and glucagon receptors and the cellular and metabolic signalling pathways associated with it. Published work addresses, among other topics, the receptor selectivity and balance of the molecule at the three target receptors, downstream signalling cascades in cell models, and comparative questions concerning mono-, dual- and triple agonists of the incretin class. Reproducible laboratory work rests on batch-specific identity and purity documentation together with appropriate storage of the material.<\/p>\n<h2>What does &#8220;GLP-3&#8221; mean?<\/h2>\n<p>&#8220;GLP-3&#8221; is not a hormone of its own but a widely used informal term for the third generation of incretin-based research peptides: GLP-1 mono-agonists (for example semaglutide) were followed by dual GIP\/GLP-1 agonists (for example tirzepatide), and then by Retatrutide as the triple agonist that additionally addresses the glucagon receptor. Searches for &#8220;GLP-3&#8221; or &#8220;GLP3 peptide&#8221; usually refer to Retatrutide as research material. Pept\u00e9lia stocks Retatrutide GLP-3 in 5, 10, 15 and 20 mg as well as in a capsule formulation, each with a batch-specific COA.<\/p>\n<h2>Retatrutide GLP-3 from Pept\u00e9lia<\/h2>\n<p>Retatrutide GLP-3 15 mg is available from Pept\u00e9lia as research reference material \u2013 the largest nominal amount, intended for more extensive experimental series.

Further nominal amounts are Retatrutide GLP-3 5 mg, Retatrutide GLP-3 10 mg and Retatrutide GLP-3 20 mg (the latter also in packs of 3, 5 or 10 vials); all variants are listed in the Retatrutide (GLP-3) category.<\/p>\n<h3>Ordering from Pept\u00e9lia<\/h3>\n<ul>\n<li>Select the pack size above: 1, 3, 5 or 10 vials \u2014 the larger the pack, the lower the price per vial<\/li>\n<li>Dispatched from Germany on the next business day<\/li>\n<li>Delivery times vary by destination<\/li>\n<li>Free shipping on orders over \u20ac100<\/li>\n<li>Bacteriostatic water for reconstitution included with every order<\/li>\n<li>Batch certificate of analysis viewable before purchase<\/li>\n<li>Discreet, unbranded packaging<\/li>\n<\/ul>\n<h2>Quality &amp; documentation<\/h2>\n<p>Every batch ships with a <strong>batch-specific certificate of analysis (COA)<\/strong>.
