The Beauty Stack XL is KPV, GHK-Cu supplied together as one item — the same pairing as the standard Beauty Stack, but with GHK-Cu 100mg instead of 50mg — for $263.80 (the vials separately come to $273.73). 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

  • KPV (10mg) — a tripeptide fragment of alpha-MSH studied in anti-inflammatory and skin-barrier research.
  • GHK-Cu (100mg) — the copper tripeptide that anchors skin, collagen and extracellular-matrix research, here at double the vial strength of the standard Beauty Stack.

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.

XL vs the standard Beauty Stack

Same pairing, higher GHK-Cu dose: the XL uses GHK-Cu 100mg instead of 50mg alongside the same KPV 10mg vial. Everything else about the stack — how the two compounds are studied together, storage, dispatch — is identical to the standard Beauty Stack; the only difference is how much GHK-Cu is in the second vial.

Why these compounds are studied together

KPV is studied for its anti-inflammatory activity and its interaction with skin-barrier pathways, independent of the melanocortin-receptor binding that drives its parent molecule's pigmentation effects. GHK-Cu sits on the remodelling side of the same research picture — collagen synthesis, elastin and wound-related gene expression. Paired together, they let researchers look at inflammation and remodelling in the same skin-research model without combining the compounds in one vial. A stack keeps each compound separate, 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

Both 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 Beauty 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. Each batch is independently tested for purity (HPLC) and identity (mass spec), with the Certificates of Analysis published. The stack is $263.80, against $273.73 for the two vials bought separately — a saving of $9.93; standard bulk pricing applies from three stacks. New to buying research peptides?

Common questions about the Beauty Stack XL

What is the Beauty Stack XL?
Two separate research peptides supplied together: KPV 10mg + GHK-Cu 100mg. Sold as one item by NextGen Peptides for laboratory and in-vitro research use only.

How is the Beauty Stack XL different from the standard Beauty Stack?
Same pairing, higher GHK-Cu dose: the XL uses GHK-Cu 100mg instead of 50mg alongside the same KPV 10mg vial, for researchers who want more GHK-Cu per stack.

Is the Beauty Stack XL 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.

How much does the Beauty Stack XL cost in Australia?
$263.80 for both vials. Bought separately they come to $273.73, so the stack saves $9.93. Bulk pricing applies from three stacks.

Is the Beauty 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.
