The Furnace Stack

The Furnace Stack is a metabolic reset protocol built for adults pursuing serious body recomposition. It pairs mitochondrial activation with a next-generation ERR-agonist to support cellular energy, metabolic flexibility, and the way your body uses fuel at rest and under load.

MitoShred is our metabolic support formula engineered to prime mitochondrial output and substrate utilization. SLU-PP-332 (250mcg tablets, 120 ct) is a novel ERR-agonist designed to support endurance signaling, fat oxidation pathways, and exercise-mimetic effects at the cellular level.

Both components are doctor-formulated under Dr. Amy Seinfeld, D.O., manufactured in our Florida GMP-Certified, SQF Level 2 facility, and third-party batch tested for purity and potency. Better ingredients. Smarter formulations. Real results.
