GLP-1 Weight Loss Injections

GLP-1 (glucagon-like peptide-1) receptor agonist medications represent the most significant advance in medical weight management in a generation. Halley Body Slimming Clinic offers three classes of these injectables, all prescribed and supervised by a licensed physician.

Liraglutide — the original GLP-1 agonist marketed as Victoza and Saxenda — mimics a naturally occurring gut hormone that regulates appetite and blood sugar. Injected daily, it suppresses appetite, slows gastric emptying, and promotes satiety. Clinical trials demonstrated average weight loss of 5–8% of body weight over 56 weeks compared to placebo.

Semaglutide represents the next generation — a once-weekly GLP-1 agonist that achieves greater receptor binding duration. Sold globally as Ozempic (diabetes indication) and Wegovy (weight management), semaglutide trials have demonstrated average weight loss of 15% of body weight, making it substantially more effective than Liraglutide for most patients. The clinic offers semaglutide at SGD 1,250 per injection pen.
