In Colombia it is available in presentations of <strong>5 mg and 10 mg<\/strong> in lyophilized vial.

The chemical modification with respect to natural GHRH gives it greater metabolic stability, allowing a longer biological effect.<\/p>\n\n\n\n<p>It was approved by the FDA in 2010 under the trade name Egrifta for the treatment of HIV-associated lipodystrophy in patients on antiretroviral therapy. Due to its mechanism and pharmacological profile, it is still under investigation in other contexts related to the GH\/IGF-1 axis.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"mecanismo\">Mechanism of action<\/h2>\n\n\n\n<p>Tesamorelin acts on the <strong>GHRH receptors<\/strong> in the anterior pituitary, stimulating the natural release of growth hormone (GH). In turn, GH acts on the liver promoting the production of IGF-1, a key factor in many metabolic, anabolic and tissue repair processes.<\/p>\n\n\n\n<p>The most studied characteristics are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Pulsatile GH stimulation<\/strong>The natural release pattern is maintained, as opposed to the direct administration of exogenous GH.<\/li>\n<li><strong>Increased IGF-1<\/strong>downstream effect documented in published clinical studies.<\/li>\n<li><strong>Modulation of lipid metabolism<\/strong>Clinical research has documented visceral fat reduction in specific subjects.<\/li>\n<li><strong>Resistance to degradation<\/strong>better stability with respect to endogenous GHRH.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"presentaciones\">Presentations available in Colombia<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table>\n<thead><tr><th>Presentation<\/th><th>Format<\/th><th>Typical research use<\/th><\/tr><\/thead>\n<tbody>\n<tr><td><a href=\"https:\/\/peptilife.co\/en\/product\/tesamorelin-5mg\/\">Tesamorelin 5 mg<\/a><\/td><td>Lyophilized vial<\/td><td>Standard research<\/td><\/tr>\n<tr><td><a href=\"https:\/\/peptilife.co\/en\/product\/tesamorelin-10mg\/\">Tesamorelin 10 mg<\/a><\/td><td>Lyophilized vial<\/td><td>Extended protocols<\/td><\/tr>\n<\/tbody>\n<\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"donde-comprar\">Where to buy Tesamorelin in Colombia?<\/h2>\n\n\n\n<p>For Tesamorelin the quality of the supplier is especially important because of the sensitivity of the peptide.

In Colombia, Tesamorelin is distributed exclusively for scientific research purposes. Although it has FDA approval for a specific indication (HIV lipodystrophy), it is not approved by Invima as a prescription drug.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is the difference between Tesamorelin and CJC-1295?<\/h3>\n\n\n\n<p>Both are GHRH analogs but Tesamorelin has FDA approval and a well-documented clinical profile. CJC-1295 is more studied in a research setting and exists in versions with and without DAC (which alters the half-life).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How long does shipping take in Colombia?<\/h3>\n\n\n\n<p>Between 24 and 72 business hours for major cities such as Bogota, Medellin, Cali, Barranquilla, Cartagena. Up to 5-7 business days for remote areas.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How long does it last when reconstituted?<\/h3>\n\n\n\n<p>Once reconstituted with bacteriostatic water and stored refrigerated at 2-8\u00b0C, it lasts up to 45 days.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"conclusion\">In a nutshell<\/h2>\n\n\n\n<p>Tesamorelin is one of the most clinically documented GHRH analogues. For research on the GH\/IGF-1 axis it remains one of the most relevant molecules due to its combination of metabolic stability and well-characterized pharmacokinetic profile.<\/p>\n\n\n\n<p>Check the available options: <a href=\"https:\/\/peptilife.co\/en\/product\/tesamorelin-5mg\/\"><strong>Tesamorelin 5 mg<\/strong><\/a> y <a href=\"https:\/\/peptilife.co\/en\/product\/tesamorelin-10mg\/\"><strong>Tesamorelin 10 mg<\/strong><\/a>.
