GHK-Cu in brief
GHK-Cu comes in 2 strengths from 50mg to 100mg per vial, each a sealed box of ten, from $32.20 to $52.00 a box. Per mg the spread is narrow: CU100 (100mg x 10 vials) works out at $0.052 per mg against $0.064 per mg for CU50 (50mg x 10 vials), 19 percent less for the same mg, because the vial, the fill and the testing cost about the same whatever the vial holds.
Every strength is on the shelf today and leaves in 1 to 2 business days after payment clears; CU50 and CU100 are running low.
What GHK-Cu is
GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine. The peptide alone has mass 340.4; the complex the sheet describes, C14H22CuN6O4, has average mass 401.9 and is a blue to blue-violet powder, the colour coming from the copper bound between the histidine imidazole and the backbone amines. A white cake on this line is the wrong thing.
Identity on its certificate is the tripeptide by mass; a complete 1:1 complex is about 15.8 percent copper by weight, and the desk can be asked for a given batch’s copper content. The peptide is very hygroscopic and the complex is blue. It is also co-formulated with BPC-157 and TB-500 in GLOW70, GLOW50, KLOW80 and the Lemon Bottle blend, and with KPV and BPC-157 in GKP70.
Registry and identity
- FDA's GSRS lists the 1:1 complex this line is specified as under the name prezatide copper, also copper tripeptide-1: UNII 6BJQ43T1I9, CAS 89030-95-5, DrugBank DB14683, PubChem CID 10111685, formula C14H22CuN6O4, average mass 401.9. FDA GSRS, PubChem
- The INN prezatide copper acetate (WHO Proposed INN List 67, also USAN, code PC-1020) is a different stoichiometry, two GHK chains per copper as the acetate, CAS 130120-57-9, C32H54CuN12O12, 862.4; copper is about 15.8 percent of the 1:1 complex by weight and about 7.4 percent of the 2:1 acetate. FDA GSRS, PubChem
- Without its metal the tripeptide is prezatide, INCI name tripeptide-1 (UNII 39TG2H631E, CAS 49557-75-7, ChEBI 75430, DrugBank DB11296), and GHK acetate has a number of its own, CAS 72957-37-0. FDA GSRS 39TG2H631E, FDA GSRS 8AA809EUS9
- Copper has two stable isotopes, 63Cu at 69.15 percent and 65Cu at 30.85 percent; worked from them with NIST isotope masses, the complex's protonated ion is m/z 402.107 with 63Cu and 404.105 with 65Cu, and the tripeptide without its copper m/z 341.193. NIST, PubChem 10111685, PubChem 73587
A listing in these registers identifies a substance; it is not an approval of this line.
GHK-Cu beside TB-500 and BPC-157
GHK-Cu works out at $0.052 per mg at 100mg (CU100), its lowest by the single box. Its neighbours, on price alone: TB-500 at $1.034 per mg at 10mg (TB10), 4,963.5 g/mol, set side by side in GHK-Cu vs TB-500; BPC-157 at $0.553 per mg at 10mg (BC10), 1,419.6 g/mol, set side by side in BPC-157 vs GHK-Cu.
Reading a GHK-Cu certificate of analysis (COA)
- A blue-violet powder is correct.
- Identity is the tripeptide by mass; ask the desk for the copper content of a batch.

Questions about GHK-Cu
What are GHK-Cu’s sequence, formula, molecular weight and CAS number?
Gly-His-Lys, the tripeptide glycyl-L-histidyl-L-lysine, bound 1:1 to copper(II): C14H22CuN6O4, molecular weight (average mass) 401.9, CAS 89030-95-5, which FDA’s GSRS lists as prezatide copper (UNII 6BJQ43T1I9). The copper-free tripeptide, prezatide, is filed apart under CAS 49557-75-7 at 340.4: those two figures belong to the bare peptide, and 401.9 and 89030-95-5 to GHK-Cu, the copper complex.
How much of GHK-Cu is copper by weight, and does any other line carry a metal?
About 15.8 percent: copper’s 63.5 in the complex’s 401.9. GHK-Cu’s formula is the bare tripeptide’s, C14H24N6O4, with copper in place of two hydrogens, which is why the complex weighs 61.5 more than 340.4. The same copper is in the five blends that carry GHK-Cu: GLOW70, GLOW50, KLOW80, GKP70 and the Lemon Bottle blend. Of the single compounds, one other carries a metal: Vitamin B12, cyanocobalamin, C63H88CoN14O14P at 1,355.4, whose corrin ring holds a single cobalt, about 4.3 percent of its mass, and which Lipo-C with B12 carries too. No other line’s formula holds a metal.
How much does GHK-Cu cost?
From $32.20 a sealed box of 10 vials, up to $52.00 for the largest strength sold singly, which works out at $0.052 per mg at its best-priced size. To a US address, freight is included from $1,000 of goods; below that it is the carrier’s rate for the carton or a flat $35.00, and to another country the desk quotes it; either way the figure is on the proforma before you pay. Every strength and its price per vial is in this page’s price table.
Which GHK-Cu size is cheapest per mg?
CU100, 100mg x 10 vials, at $0.052 per mg, which is 19 percent less per mg than CU50, at $0.064 per mg. Larger vials cost less per mg across this range, so match the vial to the size of the work first, then compare per mg.
Can I buy a single vial of GHK-Cu?
No. One sealed box of ten vials is the smallest quantity of a regular line; for GHK-Cu that is CU50, 50mg x 10 vials, at $32.20. A first order must reach $100 of goods, so CU50 alone takes four boxes ($128.80) or one box beside other lines. A box is sealed at fill with its batch number on it, and splitting one would break the link between the vials and their certificate.
Which GHK-Cu strengths are in stock today?
CU50 at $32.20 a box (running low), CU100 at $52.00 a box (running low). Every strength is on the shelf.
How is GHK-Cu stored?
At minus 20 degrees Celsius, dark and dry. Lyophilised powder tolerates a short spell at ambient temperature in transit, which is why boxes ship without ice. Storage and handling.
What is in a box of GHK-Cu?
Ten sealed vials of one strength, each labelled with the product code, the strength and the batch number; the trade also calls a box a 10-vial kit. GHK-Cu is supplied as a powder in a sealed glass vial and in no other presentation. Boxes are not split.
Is a certificate of analysis (COA) provided for GHK-Cu?
Yes. For GHK-Cu the batch certificate reports its purity, net content and identity by mass spectrometry. The other lines on this page are the specification it is made to, and the desk answers for them on a particular batch. The certificate is sent with the shipment, and again on request, and any batch number can be verified on the certificate page.
Is this for human use?
No. Everything here is supplied for laboratory research only, to trade accounts, and is not for human or animal consumption. The research-use page sets out who can buy and what is not sold.
