WEIGHT MANAGEMENT & BODY COMPOSITION

Weight management research extends well beyond a single number on the scale, encompassing appetite regulation, energy balance, metabolic signalling, fat metabolism and body-composition pathways. This collection brings together compounds representing several areas of ongoing scientific investigation. Retatrutide and Tirzepatide are studied within metabolic and appetite-regulation research, while AOD-9604 is associated with research into fat metabolism. MOTS-c provides a cellular-energy and mitochondrial perspective, and 5-Amino-1MQ represents emerging research into metabolic pathways. Explore the science behind the complex biological systems that influence body composition and energy metabolism, and discover how researchers are investigating new approaches to understanding these pathways. This collection is intended for research and educational purposes only and does not constitute medical advice or a recommendation for weight-loss treatment.

Every product in this stack goes into your cart as its own item, in whichever size and format you choose. Once all 4 of them are in the cart the 20% discount is applied automatically — you don't need a code. Remove one and the discount comes off until it's back.

Each vial arrives as lyophilized (freeze-dried) powder and must be reconstituted with bacteriostatic water before use in a research setting. Add the water slowly down the inside wall of the vial, then swirl gently until clear — never shake. Once reconstituted, keep it refrigerated and use within 28 days.

Sealed lyophilized vials are stable at ambient temperatures for 30 days and indefinitely at −20°C. After reconstitution, refrigerate at 2–8°C in the original vial and use within 28 days. Keep the vial out of direct light and avoid repeated temperature swings and agitation.

Quality and purity tests are performed on random batches, covering identity (mass spec), purity (HPLC) and endotoxin results — for every product in this stack.

Orders placed before 3:00 PM ET on a business day are typically shipped the same day, in plain, discreet packaging; transit is estimated at 2–4 business days.
