The Arnie Gym Stack XL is BPC-157, TB-500, the larger 40mg vial of MOTS-c and CJC-1295/Ipamorelin Blend supplied together as one item — four separately manufactured, separately tested research peptides for $649.34 (the vials separately come to $682.99). 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
- BPC-157 (10mg) — a pentadecapeptide studied in gut-lining, tendon-healing and tissue-repair research.
- TB-500 (10mg) — a Thymosin Beta-4 fragment studied in cell-migration, angiogenesis and muscle-recovery research.
- MOTS-c (40mg) — a mitochondrial-derived peptide studied in metabolic and exercise-physiology signalling research, in the larger 40mg vial.
- CJC-1295/Ipamorelin Blend (10mg) — a growth-hormone-releasing-hormone analogue paired with a selective GH secretagogue, studied in growth-hormone axis 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
This builds on the Gym Stack XL (the Wolverine pairing of BPC-157 and TB-500, plus the larger MOTS-c vial) by adding CJC-1295/Ipamorelin Blend. BPC-157 anchors local tissue-repair models, TB-500 the cell-migration and angiogenesis strand, MOTS-c the mitochondrial and metabolic-signalling angle, and CJC-1295/Ipamorelin brings the growth-hormone axis strand — a four-compound combination often examined together in training-recovery and growth-hormone-axis research. 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.
Evidence base
No study has tested this specific combination together. Each compound has its own separately published evidence, at its own evidence tier — read the research base for BPC-157, TB-500, MOTS-c and CJC-1295 / Ipamorelin on their individual pages before assuming the stack as a whole is supported by the same literature.
Storage & handling
All four 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 Arnie Gym Stack XL 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. Our peptides are independently tested for purity (HPLC) and identity (mass spec), with the Certificates of Analysis published. The stack is $649.34, against $682.99 for the four vials bought separately — a saving of $33.65; standard bulk pricing applies from three stacks. Don't need the larger MOTS-c dose?

Common questions about the Arnie Gym Stack XL
What is the Arnie Gym Stack XL?
Four separate research peptides supplied together: BPC-157 10mg + TB-500 10mg + MOTS-c 40mg + CJC-1295/Ipamorelin 10mg. Sold as one item by NextGen Peptides for laboratory and in-vitro research use only.
How is the Arnie Gym Stack XL different from the regular Arnie Gym Stack?
Same BPC-157, TB-500 and CJC-1295/Ipamorelin. The MOTS-c vial is the larger 40mg size instead of 10mg.
Is the Arnie Gym Stack XL one vial or four?
Four. 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?
BPC-157 and TB-500 are the Wolverine pairing for local tissue-repair and cell-migration research, MOTS-c brings the mitochondrial and metabolic-signalling angle, and CJC-1295/Ipamorelin Blend is studied for its growth-hormone axis signalling activity. These are fields of study, not claims about effects in humans.
How much does the Arnie Gym Stack XL cost in Australia?
$649.34 for all four vials. Bought separately they come to $682.99, so the stack saves $33.65. Bulk pricing applies from three stacks.
Is the Arnie Gym Stack XL 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.
