retatrutide research uk At the highest investigational dose (12 mg weekly): Mean weight reduction reached 24.2% at 48 weeks Weight loss continued progressively without plateau Dose-dependent efficacy was observed across cohorts Additional metabolic improvements included: Significant reductions in BMI Reduced waist circumference Lower fasting plasma glucose Meaningful HbA1c improvements Blood pressure reductions A pooled meta-analysis of randomised controlled trials confirmed statistically significant improvements in: Body weight (14.33% vs placebo) BMI (5.38 difference) Waist circumference (10.51 cm) Fasting glucose HbA1c (0.91%) Systolic and diastolic blood pressure Importantly, these improvements were achieved through combined appetite suppression and increased energy expenditure a dual mechanism not fully realised in earlier incretin therapies

Incretin based therapies such as GLP-1 receptor agonists have revolutionised management of type 2 diabetes by enhancing insulin secretion, slowing gastric emptying and reducing appetite (Dungan & DeSantis, 2025)
A meta-analysis of 10 trials totaling 71,351 patients extended these findings, showing GLP-1 receptor agonists reduced the composite kidney outcome by 17% across trials
Always solve for mg/mL first, then derive injection volume from that concentration
I dont trust weight-loss supplements, he says
