About this treatment
Medical slimming pens deliver injectable GLP-1 or dual GLP-1/GIP agonists that slow gastric emptying and reduce appetite via central pathways. Under physician supervision, average total body-weight loss is 12–18% at 12 months for semaglutide and up to 20–22% for tirzepatide.
A responsible programme includes baseline labs (HbA1c, lipids, thyroid, renal, pregnancy status where relevant), dose titration over 8–16 weeks, monthly clinical review, and a lifestyle/nutrition plan to preserve lean mass. Therapy is medical — not cosmetic — and typically continues for 12+ months.
