Established Retatrutide stacks
Lean-Mass Preservation During Aggressive Weight Loss
Goal: Preserve skeletal muscle during rapid weight reduction
Given the scale of weight loss seen with retatrutide, researchers have modeled pairing with GH secretagogues (Ipamorelin, Sermorelin) to study lean-mass preservation during aggressive caloric deficit. This is a research hypothesis, not a clinical recommendation.
How to think about stacking
- Mechanism diversity beats redundancy. Pairing compounds that hit different pathways usually outperforms stacking two compounds with similar mechanisms.
- Track one variable at a time. Starting two peptides simultaneously makes it impossible to attribute effects. Research protocols typically introduce stacks sequentially.
- Side-effect interactions. Some peptides compound each other's side effects (e.g., GLP-1 agonists with other GI-active compounds). Review side-effect profiles before stacking.
