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.

Third Party Testing
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.
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.

HGH Fragment 176-191 is the last 16 amino acids of the growth hormone molecule, isolated on the basis that the fat metabolising activity of GH appears to sit in that region of the chain while the growth promoting activity sits elsewhere.
The premise is straightforward: if the lipolytic and the anabolic effects of growth hormone can be separated by using only part of the molecule, then the fragment should influence fat metabolism without raising IGF-1, without the glucose effects that follow GH administration, and without the growth signalling. Animal work in the 1990s and early 2000s supported that separation reasonably well.
Human evidence is where it becomes complicated. AOD-9604, a modified version of this same fragment, was taken into human trials by an Australian company and failed to produce meaningful weight loss against placebo in a phase IIb study. That result is the single most important piece of evidence about this fragment, and it is not a favourable one. It is worth knowing before choosing it over a GLP-1.
The pen format
Fragment protocols in the literature are frequent, small and timed around fasted periods, which makes a dial far more practical than reconstituting and drawing. 15mg gives 30 full 500mcg draws.
- 15.00mg of HGH Frag 176-191 per pen, in solution and ready to use
- 1 unit = 50mcg. 10 units on the dial gives 500mcg
- 300 units in total, which works out at 30 full 500mcg 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
- 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 HGH Fragment 176-191 15mg pre-filled injection pen
- 4 × sealed pen tips, 32G 0.23 x 4mm
- Serialised, QR coded retail carton
Choosing between the Fragment, AOD-9604 and a GLP-1
AOD-9604 is this same fragment with a tyrosine added to stabilise it, and it is the version that actually went through human trials. If you want the better characterised of the two, it is AOD. If you want more material for the money, the fragment pen carries three times the peptide of a 5mg AOD vial.
The harder comparison is against a GLP-1. Tirzepatide and retatrutide have large human trials behind them showing substantial weight loss; the fragment has an animal literature and a failed phase IIb. Anyone choosing the fragment for fat loss should do so knowing that the evidence gap between the two is not marginal, it is the whole thing.
Guides that go deeper:
- AOD-9604: the fat loss fragment of GH
- Fat loss compounds: three routes, one that works
- Semaglutide vs tirzepatide vs retatrutide

Quality pen great packaging. Reasonable price and very quick delivery. My go 2 store for all my products
View on Trustpilot⭐⭐⭐⭐⭐ Excellent service and fast delivery! This was my first time ordering from this company, and I was so pleased with the experience that I ordered from them again. Both times, the delivery was very quick, and the supplements were excellent quality. I’m really happy with the service and products and would happily recommend them. I will definitely order from them again!
View on TrustpilotLoving it so easy to do it is what it says it is so I’m very happy
View on TrustpilotPen work as it should, would be better if you could do 5mg in on dose
View on TrustpilotExcellent service, brilliant results "Customer service was first class. My wife has been using tirzepatide SerenQ and it's been brilliant. She's lost weight, and her mental clarity and physical appearance have improved. It's been amazing to have my happy wife back. Thank you!"
View on TrustpilotThe packaging was excellent and the pen is generally easy to use. However, I feel the injection button mechanism could be improved, as it feels slightly flimsy when pressing down to release the solution. The dial/turning function also feels like it could be made more durable and sturdy. It would be great to see more needle heads included as standard, or alternatively have the option to purchase additional needles directly through your website for convenience. Overall, a good product with some small areas that could be improved to enhance the user experience.
View on TrustpilotI’ll start by saying it works , the delivery was quick and faultless , the pen is easy to use once you get your head round dosing , I will be reordering, and have recommended to friends .
