FAQ
- What is the most effective GLP-1 combination therapy in trials right now?
- Retatrutide, a triple GIP/GLP-1/glucagon agonist from Eli Lilly, produced mean weight reductions approaching 24% at the highest dose in phase 2, the strongest single-molecule result reported to date.
- Why do GLP-1 drugs plateau and combinations help?
- Body weight is defended by redundant pathways including leptin, amylin, and energy-expenditure circuits. Combining mechanisms attacks the system from multiple angles, overcoming the compensatory biology that limits monotherapy.
- How should multi-agonist peptides be stored and reconstituted?
- Allow lyophilized powder to reach room temperature before adding diluent, use sterile water for initial dissolution of long hydrophobic sequences, aliquot under inert gas, and store at -20 °C to protect oxidation-prone residues.
