Fat Burner

Torch visceral fat & tone muscle

Fat Burner is a physician-prescribed peptide protocol combining AOD-9604, CB4211, and Tesamorelin; three compounds that address fat metabolism through distinct biological mechanisms. AOD-9604 stimulates lipolysis and inhibits fat cell formation, CB4211 enhances insulin sensitivity and fatty acid metabolism, and Tesamorelin targets visceral fat through growth hormone-mediated pathways.


Unlike most peptide protocols administered in the evening, Fat Burner is taken each morning on an empty stomach to align with the body's fasted metabolic state and maximize fat oxidation.

Fat Burner
  • Targets visceral fat (belly fat) and increases metabolism
  • Stimulates lipolysis (fat cell breakdown)
  • Enhances insulin sensitivity and fatty acid metabolism
  • Supports deeper sleep
  • Helps with bone density
  • Supports lipid metabolism
  • Promotes a balanced inflammatory response
  • Supports heart health
  • Increases calories burned by boosting metabolism
  • Supports bone and cartilage repair
  • AOD-9604
  • CB4211
  • Tesamorelin
  • 20IU SubQ
  • Monday-Friday (a.m. - best on empty stomach)
  • 5 or 10 weeks

Fat Burner is administered as a subcutaneous (SubQ) injection, with a 30G/31G syringe at the prescribed dosage.

How Fat Burner Works

Fat Burner approaches fat metabolism from three simultaneous angles; AOD-9604 triggers the breakdown of existing fat cells and prevents new ones from forming, CB4211 enhances the body's insulin sensitivity to improve how it metabolizes fat, and Tesamorelin targets visceral adipose tissue through growth hormone stimulation. Each compound contributes a specific and non-redundant mechanism, making the formulation more comprehensive than any single fat-targeting compound could achieve alone.

AOD-9604 is a synthetic fragment of the human growth hormone molecule, specifically the region responsible for HGH's fat-metabolizing properties. It stimulates lipolysis—the breakdown of stored fat cells into free fatty acids the body can use as fuel—and simultaneously inhibits lipogenesis, the process by which the body forms new fat cells. Critically, AOD-9604 produces these effects without influencing blood sugar levels or insulin response, addressing a key limitation of full human growth hormone therapy and making it suitable for a wider range of patients.

CB4211 is an analog of MOTS-C, a mitochondrial-derived peptide, engineered with enhanced properties compared to the natural compound. Its mechanism centers on insulin sensitivity: CB4211 potentiates the body's insulin response by extending insulin receptor activation, which improves fatty acid metabolism and supports glucose homeostasis. In practical terms, it helps the body process fatty acids more efficiently and reduces the release of free fatty acids from fat cells; within Fat Burner Blend, CB4211 supports the metabolic conditions under which the fat mobilized by AOD-9604 can be processed effectively.

Tesamorelin is a stabilized GHRH analog that stimulates growth hormone release with a demonstrated specificity for visceral adipose tissue. Visceral fat accumulates deep in the abdominal cavity, is metabolically disruptive, and resists conventional diet and exercise interventions; Tesamorelin addresses it directly through GH-mediated fat metabolism, complementing the lipolytic and metabolic mechanisms of the other compounds in the protocol.

Fat Burner is administered as a subcutaneous injection five mornings per week on an empty stomach. Fasted-state administration maximizes the fat-oxidizing conditions under which lipolytic compounds perform most effectively. Your RegenMD provider establishes your dosing protocol based on your metabolic profile and goals, and monitors your response across the five or ten-week program.

Frequently Asked Questions

Fat Burner Blend is a three-compound peptide protocol using AOD-9604, CB4211, and Tesamorelin to target fat metabolism from multiple biological angles simultaneously. AOD-9604 drives lipolysis and inhibits fat cell formation, CB4211 enhances insulin sensitivity and fatty acid metabolism, and Tesamorelin addresses visceral fat accumulation through growth hormone stimulation. The protocol is administered five mornings per week on an empty stomach over a five or ten-week program.

AOD-9604 is derived from the specific segment of the human growth hormone molecule responsible for its fat-metabolizing function, isolated from the regions that influence insulin and glucose. By targeting only the lipolytic mechanism of HGH, it stimulates fat cell breakdown and inhibits new fat formation while leaving blood sugar regulation entirely unaffected. This selectivity distinguishes it from full growth hormone therapy and makes targeted fat reduction accessible without the metabolic trade-offs associated with broader HGH protocols.

CB4211 is an analog of the mitochondrial-derived peptide MOTS-C, engineered for improved metabolic activity. Its role centers on insulin sensitivity: it potentiates the body's insulin response by extending insulin receptor activation, which improves fatty acid metabolism and supports stable glucose levels. Within Fat Burner Blend, CB4211 addresses metabolic efficiency; where AOD-9604 breaks down fat cells and Tesamorelin targets visceral deposits, CB4211 helps improve the insulin-driven processes that determine how efficiently the body handles that mobilized fat.

Fasted-state administration enhances the effectiveness of lipolytic compounds by aligning with the body's natural fat-burning conditions. When fasting, insulin levels are low and the body is already drawing on stored fat for energy; introducing lipolytic peptides at this moment amplifies an existing metabolic process rather than competing with food-driven insulin activity. Morning dosing also coincides with naturally elevated cortisol levels that support fat mobilization, making both the timing and fasted requirement deliberate components of the protocol.

Both protocols include Tesamorelin and target body composition, but their emphasis and broader mechanisms differ.

Define Stack is formulated around growth hormone optimization through Sermorelin, IGF-1, and Tesamorelin; visceral fat reduction is one outcome among several that include lean tissue preservation, anti-aging, and recovery.

Fat Burner Blend is more specifically focused on fat metabolism, pairing AOD-9604's direct lipolytic action and CB4211's insulin-sensitizing effect with Tesamorelin's visceral fat targeting. Patients whose primary objective is fat reduction rather than broader hormonal recomposition may find Fat Burner Blend better suited to their goals.
