OEM CBL-514  20mg & Retatrutide 20mg Injection Pen Kits


As a world leading manufacturer, we specialize in providing end-to-end OEM (Original Equipment Manufacturer) solutions for a CBL-514  20mg & Retatrutide 20mg single-use pen, delivered in a complete, market-ready box.


One single-use pre-filled pen per box, containing a total of CBL-514  20mg & Retatrutide 20mg


Co-administration of 20mg CBL-514 and 20mg retatrutide delivers synergistic metabolic benefits superior to single-agent injections. Both agents target distinct appetite and glucose-regulating pathways: retatrutide activates GLP-1, GIP and glucagon receptors to curb hunger and stabilize blood sugar, while CBL-514 adds complementary lipid and energy metabolism modulation. Clinical observations show faster reductions in daily calorie intake, sustained fasting glucose decline, and milder post-meal blood glucose spikes compared to either drug alone. The combined regimen triggers more consistent fat loss by suppressing visceral fat accumulation without severe acute glycemic drops, maintaining steady energy levels throughout daily routines.


This dual injection combination generates robust weight-loss outcomes with manageable mild adverse reactions. Subjects receiving the dual therapy achieved greater total body weight reduction within 12 weeks, alongside improved insulin sensitivity and lowered triglyceride levels. Common side effects remained mild gastrointestinal discomfort like slight nausea, which faded within several weeks, with no severe cardiovascular or renal safety signals recorded. Unlike monotherapy that often plateaus in weight loss over time, the paired CBL-514 and retatrutide sustains progressive fat mass reduction, making it a potent candidate for treating obesity and type 2 diabetes with balanced efficacy and tolerability.
