The Fat Burn Stack is Retatrutide, MOTS-c supplied together as one item — two separately manufactured, separately tested research peptides for $289.00 (the vials separately come to $305.80). This page covers what is in the stack, why the pairing is studied, and how to source it with documentation from Australian stock. It is supplied strictly for laboratory and in-vitro research use.
What is in the stack
- Retatrutide (10mg) — a triple-receptor GIP/GLP-1/glucagon agonist peptide, the most-studied compound in current metabolic and body-weight research.
- MOTS-c (10mg) — a mitochondrial-derived peptide studied in cellular-energy, exercise and metabolic research.
These describe fields of scientific study — they are not claims about effects in humans. The stack name is a product name, not a description of what the compounds do in a person. NextGen Peptides supplies every compound strictly for laboratory and in-vitro research use.
Why these compounds are studied together
Retatrutide sits in the receptor-agonist strand of metabolic research (appetite, blood-sugar and body-composition models), while MOTS-c comes at metabolism from the mitochondrial side — cellular energy and exercise-response research. The two are examined together because they approach the same field from different mechanisms. Unlike a single-vial blend, a stack keeps each compound in its own vial, so quantities can be varied independently and each vial carries its own Certificate of Analysis. See our peptide stacking guide for stacks versus blends, or build your own combination in the Stack Builder.
Storage & handling
All two vials are supplied as lyophilised (freeze-dried) powder. Store at −20°C. Each vial is reconstituted separately with bacteriostatic water — they are never combined — then refrigerated at 2–8°C and kept out of light. See storing and reconstituting research peptides, our bacteriostatic water guide, and the reconstitution calculator for each vial's concentration.
Sourcing the Fat Burn Stack in Australia
Every vial is held in Australian stock, so orders placed before the daily cut-off are dispatched same or next business day — no overseas freight, no customs wait. Each batch is independently tested for purity (HPLC) and identity (mass spec), with the Certificates of Analysis published. The stack is $289.00, against $305.80 for the two vials bought separately — a saving of $16.80; standard bulk pricing applies from three stacks. New to buying research peptides?

Common questions about the Fat Burn Stack
What is the Fat Burn Stack?
Two separate research peptides supplied together: Retatrutide 10mg + MOTS-c 10mg. Sold as one item by NextGen Peptides for laboratory and in-vitro research use only.
Is the Fat Burn Stack one vial or two?
Two. Each compound arrives in its own labelled vial with its own batch number and Certificate of Analysis, and is reconstituted and stored separately.
Why are these compounds studied together?
Retatrutide sits in the receptor-agonist strand of metabolic research (appetite, blood-sugar and body-composition models), while MOTS-c comes at metabolism from the mitochondrial side — cellular energy and exercise-response research. The two are examined together because they approach the same field from different mechanisms. These are fields of study, not claims about effects in humans.
How much does the Fat Burn Stack cost in Australia?
$289.00 for all two vials. Bought separately they come to $305.80, so the stack saves $16.80. Bulk pricing applies from three stacks.
Is the Fat Burn Stack held in Australian stock?
Yes. Every vial is held in Australian stock and dispatched same or next business day for orders placed before the daily cut-off.
