GHK-Cu 50mg ships as a 50mg lyophilized vial at $52, held in stock in the United States and dispatched the same day on orders placed before 4PM ET. Purity is 98% or higher. Bundle pricing lowers the per-vial price at two, three and five units, so five vials land at $44 each, applied in the cart with no code.
What researchers look for in a GHK-Cu supplier
GHK-Cu is listed by nearly every supplier and the quality spread is large, because a copper complex can be underloaded, overloaded or only partly complexed and still look like the same blue powder. What separates suppliers is whether the vial is on a shelf today, whether the price is published, and whether the parcel moves the day you order.
Stock that is on a shelf, not on a forecast. We hold GHK-Cu in the United States and the listing carries a live count that comes down when you order. There is no drop ship leg on your parcel and no back order queue presented as a lead time.
Published pricing with no quote step. One vial is $52. Two are $49 each, three are $46 each, five are $44 each. The bundle discount applies in the cart automatically, so there is no code to find and no quote step in between.
Dispatch measured in hours, not days. A 4PM ET cutoff sends the vial out the same day, seven days a week, weekends included. Tracking reaches you on the way out the door. Standard Shipping costs $12 and lands in 2 to 5 business days, free over $150.
A specification you can plan against. Every vial is 50mg of lyophilized GHK-Cu at 98% or higher purity, CAS 49557-75-7, molecular weight 403.92 Da. Material below that purity standard is not listed, and the specification does not drift between batches, so a protocol written against one vial holds for the next.

What GHK-Cu is, in research terms
GHK-Cu pairs a three residue peptide, glycine then histidine then lysine, with one copper(II) ion that is coordinated rather than loosely mixed. The metal occupies a square planar site built from the terminal amine, the deprotonated amide nitrogen and the histidine imidazole, which is what makes the material a discrete chemical species. The formula is C14H24CuN6O4, the molecular weight is 403.92 Da, and the CAS number is 49557-75-7. Each vial holds 50mg of lyophilized powder at 98% or higher purity.
At the bench the complex earns its place by making a three way control possible. The uncomplexed tripeptide, a plain copper salt and GHK-Cu itself can be run at matched molar concentrations in adjacent wells, which tells a peptide effect apart from a metal effect and from a coordination effect in one experiment. Few reagents allow that split. The powder dissolves in water, holds up as a dry solid, and reaches a defined micromolar working concentration in culture medium without a cosolvent.
The published preclinical literature works mainly in primary human dermal fibroblasts, keratinocyte cultures, collagen lattice contraction models and full thickness skin equivalent constructs, with rodent and rabbit wound models supplying the in vivo record. Assay classes run from UV visible and circular dichroism characterization of the copper site, through quantitative PCR, immunoblot and ELISA matrix protein panels, to scratch closure and migration assays. Our write up of that work is here: GHK-Cu Research: Copper Peptide, Fibroblast and Collagen.

GHK-Cu earns a multi-vial order because its defining control is three armed: the uncomplexed tripeptide, a plain copper salt, and the complex itself at matched molar concentrations. Each arm is its own material draw, and a fibroblast series repeated across passages is several more. Order two and every vial drops 5%, three and it drops 10%, five and it drops 15%, floored to whole dollars by the cart. At five the order passes $150, where US shipping costs nothing, and the set comes from one handling batch.
US stock, international shipping and same-day dispatch
Orders placed before 4PM ET are dispatched the same day, seven days a week. That includes Saturday and Sunday, which is where a weekday only supplier quietly costs you two days. Tracking is emailed the same day the parcel leaves, not once it is scanned somewhere downstream. Nothing waits on a Monday pick run or on an outside warehouse to open.
US Standard Shipping is $12 and arrives in 2 to 5 business days, free on orders over $150. Expedited 2-3 Day is $39 and Overnight is $95. Standard International is $40 flat and arrives in 10 to 20 business days, free on orders of $500 and above. Express International is $100 flat and arrives in 5 to 10 business days.
Storage and handling
Keep the sealed lyophilized vial at 2 to 8C, dry and protected from light, with the seal intact until it goes into use. Let a cold vial reach room temperature before the stopper is pierced so condensation does not form. Once reconstituted with bacteriostatic water, the vial goes back to 2 to 8C, upright and dark. Full handling detail is in storage and handling page, and reconstitution calculator does the concentration arithmetic for any reconstitution volume.
Checkout, payment and support
Checkout takes Visa and Mastercard directly on the site and finishes in one pass. There is no crypto detour, no wallet to fund, and no invoice emailed back for a bank transfer. Card details are entered once, the order confirms immediately, and the receipt arrives by email.
Support replies within one business day and a person reads it. If a vial arrives damaged or the order is wrong, send a photo and we replace it or refund it. No claim form, nothing to ship back first.

Frequently asked questions
What is GHK-Cu?
GHK-Cu is a copper(II) complex of the tripeptide glycyl-histidyl-lysine, whose residues run glycine, histidine, lysine. The copper is coordinated, not merely mixed in: the terminal amine, the deprotonated amide nitrogen and the histidine imidazole close around it in a square planar arrangement, which makes the complex a single defined chemical species. Its formula is C14H24CuN6O4, its molecular weight 403.92 Da, and its CAS number 49557-75-7. Core Research Peptides stocks it as a 50mg lyophilized powder at 98% or higher purity, for laboratory research use only.
Why buy GHK-Cu from Core Research Peptides?
Stock is held in the United States and the listing shows a live count, so an order ships from a shelf rather than from a forecast. Pricing is published in full: $52 for one vial, $49 each at two, $46 each at three and $44 each at five, applied automatically in the cart. Orders placed before 4PM ET dispatch the same day, seven days a week, with tracking emailed that day. Support replies within one business day.
What purity is your GHK-Cu?
Purity is 98% or higher. That is the standard the whole catalog is held to, and material below it is not listed. Each vial holds 50mg of lyophilized GHK-Cu powder, CAS 49557-75-7, molecular weight 403.92 Da. The specification is consistent between batches.
How fast do you ship GHK-Cu, and what does shipping cost?
Anything ordered before 4PM ET goes out that same day, with the tracking number emailed that day. The cutoff runs seven days a week, weekends included. Domestic rates are $12 for Standard Shipping, which arrives in 2 to 5 business days and is free once an order clears $150. Expedited 2-3 Day costs $39. Overnight costs $95. Every rate is shown at checkout before payment.
Do you ship GHK-Cu internationally?
Yes. Two international rates are offered, both flat. Standard International costs $40, takes 10 to 20 business days, and is free once an order reaches $500. Express International costs $100 and takes 5 to 10 business days. The 4PM ET cutoff applies to international orders exactly as it does to domestic ones. Duties and customs handling fall to the buyer.
Do you offer bundle pricing on GHK-Cu?
Yes, and it applies automatically. Two vials are 5% off the per-vial price at $49 each, three are 10% off at $46 each, and five are 15% off at $44 each, each figure floored to a whole dollar. Five vials come to $220, which saves $40 and clears the $150 free shipping threshold. A coupon code stacks on top of bundle pricing.
How should GHK-Cu be stored?
The dry powder holds best sealed at 2 to 8C, away from light, with the crimp seal untouched until the vial is put to work. Bring a refrigerated vial up to room temperature in its carton first, or condensation will settle on the cold glass. Reconstituted material returns to 2 to 8C and stays upright and dark between draws.
