UK Launch · The Ped Shop Exclusive
A new name in research peptides, landing in the UK
SerenQ Pharmaceuticals builds research peptides into sealed, pre-filled injection pens rather than lyophilised vials. No reconstitution, no bacteriostatic water, no guesswork with a syringe barrel. Dial the units you need, read them off the window, done.
SerenQ has appointed The Ped Shop as its exclusive UK stockist. Every pen sold here comes direct from the manufacturer, in sealed retail cartons, with a unique serial number and QR authenticity code on the label.

Composition & Dosing Guide
The GHK-Cu pen holds 3ml of solution across 300 units, so one unit on the dial equals 0.01ml. That works out at 16.67mg/ml GHK-Cu. As a worked example, 12 units is 0.12ml, containing 2.00mg GHK-Cu. Figures are the pen’s stated contents divided across its 300 units. For research purposes only. Not for human consumption.
Third Party Testing
Results pending
Every SerenQ batch is sent for independent analysis before it goes on general sale. Purity and identity testing for this batch is currently with Analiza, and the certificate will be published on this page the moment it lands.

StatusAwaiting report
Check back here for the full certificate, or ask us and we will send it over as soon as it is released.
Serialised & QR Verified
Every SerenQ product carries a unique serial number and a QR code printed on the label. Scan it with any phone camera and you can independently confirm the pen is genuine SerenQ stock and check its batch details before you open the carton.
One code per pen. Each one can only be registered once, so a duplicate scan is an immediate red flag.

About GHK-Cu
GHK-Cu is a copper peptide: three amino acids, glycine, histidine and lysine, bound to a copper ion. Unlike most research peptides it is not a laboratory invention. It occurs naturally in human plasma, saliva and urine, and its concentration falls steadily with age, dropping by roughly two thirds between your twenties and your sixties. That decline is what put it on the research map in the first place.
The copper is the interesting part. GHK acts as a carrier, holding the ion in a form that cells can actually take up, which is why the free tripeptide and the copper complex behave so differently in the literature. Published work has examined fibroblast activity and the synthesis of collagen, elastin and glycosaminoglycans, modulation of matrix metalloproteinases, antioxidant behaviour, and wound repair in animal models. It also appears widely in gene expression studies, where it has been reported to shift the activity of a large number of human genes.
Where the evidence sits: most of the GHK-Cu literature is in vitro work or topical application studies from the cosmetic sector. Injectable use is not clinically established, and it holds no medicines licence in the UK or anywhere else. It is supplied here strictly as a laboratory research chemical.
The pen format
This is where SerenQ does things differently. Instead of a lyophilised powder that has to be reconstituted, GHK-Cu arrives as a solution already loaded into a graduated injection pen with a dial and a dose window.
- 50mg of GHK-Cu per pen, in solution and ready to use
- 1 unit = 167mcg. 12 units on the dial gives 2mg
- 300 units in total, which works out at 25 full 2mg draws per pen
- Dial and dose window let you set the exact amount and read it back before dispensing
- 4 screw on pen tips supplied, individually sealed, 32G 0.23 x 4mm
- Protective cap, clip and a rigid retail carton for storage and transport
- Batch number, expiry and serial printed directly on the pen barrel, not just the box
Handling and storage
- Store refrigerated at 2 to 8°C. Do not freeze
- Keep in the outer carton, away from direct light
- The solution carries a distinct blue tint. That is the copper complex and is entirely normal
- Short periods at room temperature during transit are expected and normal
- Use a fresh sealed tip for each dispense and dispose of tips in a sharps container
- Expiry 12/2027 on sealed, correctly stored stock
- Keep out of reach of children and animals
What is in the box
- 1 × SerenQ GHK-Cu 50mg pre-filled injection pen
- 4 × sealed pen tips, 32G 0.23 x 4mm
- Serialised, QR coded retail carton
