The Metabolic Reset Stack: GLP-3R, Tesa+Ipa & MOTS-C Research Guide
Research guide to the Metabolic Reset Stack — GLP-3R (Retatrutide), Tesamorelin + Ipamorelin, and MOTS-C. Three systems, one protocol. For Research Use Only.

What Is the Metabolic Reset Stack?
The Metabolic Reset Stack is a three-peptide research protocol designed to address metabolic function across three distinct biological systems simultaneously.
The stack consists of:
• GLP-3R (Retatrutide) — Triple receptor agonist targeting GLP-1, GIP, and glucagon receptors
• Tesamorelin + Ipamorelin Blend — Growth hormone releasing hormone analog and GH secretagogue
• MOTS-C — Mitochondrial peptide targeting cellular energy production
Each peptide in the stack operates through a different mechanism, covering systems that the others cannot. This is what makes the combination a research protocol rather than simply three individual peptides.
⚠️ All peptides are for Research Use Only (RUO). Not for human consumption. Not medical advice. Not FDA evaluated. Must be 21+.
Why Retatrutide Alone Isn't the Full Picture
Retatrutide (GLP-3R) has generated significant research interest for its triple receptor activation — simultaneously targeting GLP-1, GIP, and glucagon receptors. Phase 3 clinical data from the TRIUMPH-4 trial demonstrated compelling results in metabolic research models.
However, Retatrutide’s mechanism does not address two critical metabolic systems:
1. The growth hormone axis — Retatrutide has no direct mechanism acting on GHRH signaling or GH secretagogue pathways
2. Mitochondrial function — Retatrutide does not address cellular energy production at the mitochondrial level
