Products in this category

  • GHK-Cu 50MG — a naturally-occurring copper-binding peptide studied in skin, collagen and cellular research.
  • GHK-Cu 100MG — the same compound at double concentration, for reaching a target concentration in a smaller reconstitution volume.
  • KPV — studied for its anti-inflammatory research profile.
  • Beauty Stack — KPV + GHK-Cu 50MG combined, priced below buying both separately.
  • Beauty Stack XL — KPV + GHK-Cu 100MG, the higher-concentration pairing.
  • Skin & Recovery Stack — GHK-Cu 50MG + BPC-157, pairing skin/cellular and tissue-repair research.
  • GLOW Blend and KLOW — multi-compound blends built around this category.

GHK-Cu 50MG vs 100MG

Both vials contain the same compound — the only difference is concentration. A 100MG vial reconstituted in the same water volume as a 50MG vial yields double the concentration per mL, letting a researcher reach a target dose in a smaller injection or pipette volume. Read the full GHK-Cu dosing guide for the concentration math.

Quality you can verify

Every skin and cellular research peptide we hold is independently tested for purity (RP-HPLC) and identity (LC-MS), with the Certificate of Analysis published in our CoA Library before you order. Read more on our testing & quality page.

Stock, dispatch & pricing

GHK-Cu, KPV and every stack built from them are held in Australian stock in Melbourne and dispatch same or next business day. Automatic bulk pricing applies from 3 units, with bigger savings at 5 and 10. New to reconstitution? Our peptide reconstitution calculator walks you through dosing math for any vial size.

Frequently asked questions

What are skin and cellular research peptides?
A class of peptides studied for their role in skin, collagen and cellular research. GHK-Cu and KPV are the two core compounds in this category. Supplied strictly for laboratory and in-vitro research use only.

What's the difference between GHK-Cu 50MG and 100MG?
Both are the same compound at different vial concentrations — 100MG is double the concentration of 50MG in the same reconstitution volume.

What is the Beauty Stack?
A combined KPV + GHK-Cu product, priced below buying both compounds separately. The Beauty Stack XL uses the 100MG GHK-Cu vial.

Are these peptides tested and CoA-backed?
Yes — every batch is independently tested for purity and identity, with the CoA published in our CoA Library before you order.
