Semaglutide & Tirzepatide – The UK's Most Effective Weight Loss Injections
Ozempic®, Wegovy® and Mounjaro® have transformed weight loss in the UK — but their price tags and prescription requirements put them out of reach for many. Semaglutide (the active ingredient in Ozempic® and Wegovy®) and Tirzepatide (the active ingredient in Mounjaro®) are the same powerful compounds, now more accessible than ever.
Slim Shots provides clear, science-backed information on both compounds — how they work, what the clinical data shows, and what results people typically experience.
Retatrutide – The Next Generation of Weight Loss Injections
While Semaglutide and Tirzepatide have dominated headlines, the next generation is already here. Retatrutide is a triple GLP-1/GIP/glucagon receptor agonist — the most advanced weight loss injection available today. Phase 2 clinical data shows average weight reductions exceeding 24% of body weight, surpassing both Semaglutide and Tirzepatide.
Retatrutide is not yet available as a branded medicine — making it one of the most exciting developments in injectable weight loss science right now.
Melanotan 2 – UK's Most Popular Tanning Injection
Alongside weight loss compounds, Slim Shots covers Melanotan 2 (MT2) — the UK's most popular tanning injection. MT2 stimulates melanocortin receptors to increase melanin production, producing a deep, natural-looking tan with minimal sun exposure. Most users see visible results within 5–10 days.
Whether you're looking to build a base tan before a holiday or maintain a year-round glow without sunbeds, Melanotan 2 delivers fast, reliable results.
