Tirzepatide + B12 + Glycine: The Metabolic Master Formula

This custom-compounded formulation brings together Tirzepatide, a dual GLP-1/GIP receptor agonist, with Methylcobalamin (B12) and Glycine, a foundational amino acid. The result is a powerful, multi-system peptide protocol designed to enhance fat loss, glucose control, energy production, and cellular repair.

​

Why Combine Tirzepatide with B12 and Glycine?

While Tirzepatide alone offers potent weight loss and glucose management effects, its combination with B12 and Glycine addresses the energy, recovery, and neurocognitive depletion often experienced during caloric restriction and metabolic modulation.

​

Tirzepatide: Dual Incretin Precision

Originally FDA-approved for type 2 diabetes, Tirzepatide mimics both GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide) receptors. This dual action enhances:

• Insulin sensitivity & pancreatic β-cell responsiveness

• Satiety & appetite suppression

• Sustained fat oxidation & visceral fat reduction

• Glycemic control with minimal hypoglycemia risk

In clinical trials, Tirzepatide has outperformed GLP-1-only analogs (e.g., Semaglutide) for weight loss and HbA1c reduction, while supporting cardiovascular markers.

​

In a 72-week randomized trial (SURMOUNT-5) of individuals with obesity without diabetes, Tirzepatide achieved a 20.2% mean body weight reduction, compared to 13.7% with Semaglutide

​

Methylcobalamin (Vitamin B12): Energy & Nervous System Support

Tirzepatide regimens can sometimes reduce appetite to a degree that leads to nutrient shortfall or fatigue. B12 counterbalances this by:

• Supporting red blood cell formation and oxygen transport

• Enhancing energy metabolism at the mitochondrial level

• Aiding in mood, cognition, and neurological resilience

We use Methylcobalamin, the active coenzyme form of B12, for superior bioavailability and CNS delivery.
