Product Overview
Both GHK-Cu vials of the Dragon Pharma line are listed here: the 10 mg fill and the 50 mg fill. Each holds the same copper tripeptide as a lyophilised powder, a GHK sequence bound one-to-one to a copper ion, and each is reconstituted with bacteriostatic water before it is used in any research setting.
The two sizes differ only in how much material they contain and, because of that, how convenient the arithmetic is. The 10 mg vial is dosed out in small amounts and suits a short experiment; the 50 mg vial carries five times the powder and suits longer protocols or work that uses larger quantities at once.
The warning that belongs at the top is about evidence rather than handling. Almost all published work on this complex comes from cell cultures and from topical application, no human half-life has ever been established, and the catalogue vials are research material rather than an approved medicinal product. Nothing below describes a validated human dose, because none exists in the sources.
The Two Vial Sizes
GHK-Cu 10 mg
The smaller fill. Because the vial holds only 10 mg, the dilution arithmetic has to be planned before the solvent is added: a small volume of water produces a concentrated solution that is hard to measure accurately, so most research notes use a larger volume instead and accept a weaker concentration.
GHK-Cu 50 mg
The larger fill, and the size most reconstitution guides are written around. A vendor guide for 50 mg suggests 2 to 5 ml of solvent, which lands between roughly 10 and 25 mg per ml depending on the volume chosen. The extra powder gives more room for error in the arithmetic.
| GHK-Cu 10 mg | Small fill; dilution must be planned before the solvent is added |
| GHK-Cu 50 mg | 2-5 ml of solvent gives roughly 10-25 mg per ml |
| Shared by both | Same copper tripeptide, same powder form, same cold chain |
What the Tripeptide Does
GHK is a three amino acid sequence that occurs naturally in human plasma and binds copper tightly; the complex is studied for collagen synthesis, wound contraction and a modulating effect on inflammation. Copper is the active part of that story, which is why the complex rather than the bare peptide is what appears in most laboratory work.
The practical consequence for anyone reading this card is a limitation, not a mechanism. Human pharmacokinetics have not been described, so there is no basis for an injection interval or a blood level target, and the quantities quoted in research models, typically 1 to 2 mg a day systemically, are model figures rather than a protocol.
Reconstitution Arithmetic
Both vials take the same solvent and the same technique, and the powder is delicate enough that the method matters as much as the numbers.
| Solvent | Bacteriostatic water, run down the wall of the vial rather than aimed at the powder |
| 50 mg vial | 2-5 ml gives roughly 10-25 mg per ml; more water means a weaker, easier-to-measure solution |
| 10 mg vial | The same volumes give one fifth of the concentration, so the vial is finished far sooner |
| Research amount | 1-2 mg a day systemically in model work; an experimental figure, not a human dose |
| Duration | No validated length of use exists in the material consulted |
Research Context and Combinations
In the catalogue this complex normally sits beside the other reparative peptides, and the combinations below are context rather than recommendations.
What to Expect
- No measurable marker. There is no published assay or blood level to track, so a protocol cannot be steered by numbers.
- Local or topical evidence. Most of what is described comes from skin and wound models, which says nothing about an injected dose.
- Powder quality matters. The lyophilisate should look uniform; clumping or discolouration after solvent is added is a reason to stop.
- Bacteriostatic water, not sterile water. The preservative is what keeps a multi-use vial usable for more than a day.
- Limitation. This is a laboratory material and no regulator has approved it for human use.
Side Effects and Precautions
Because human use is not documented, the list below is about handling and the theoretical risks of an uncharacterised peptide rather than a reported profile.
Handling and Cold Chain
Stability is the practical problem with this peptide, and it is the same for either fill size. Reparative peptides often compared with it include Epitalon and TB-500.
Which Vial Size to Choose
The 10 mg vial is the smaller commitment and the harder one to measure accurately, because small volumes of solvent turn it into a concentrated solution. Buyers who want a simple dilution and a longer shelf life after mixing take the 50 mg fill and use the vendor arithmetic of 2 to 5 ml that was written for exactly that size; buyers who only need a small quantity in one sitting take the 10 mg vial and accept that it is gone after a few reconstitutions.
Either way, add Bacteriostatic water to the same order and treat both vials as laboratory material rather than a cosmetic product. The evidence base behind the complex is thin, and no amount of careful arithmetic fills that gap.
