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.

Sermorelin is the first 29 amino acids of growth hormone releasing hormone, which is the shortest fragment that retains full biological activity. The remaining 15 amino acids of native GHRH contribute nothing to receptor binding, so sermorelin behaves as GHRH does while being far simpler to manufacture.
It works by binding the GHRH receptor on the pituitary and prompting it to release its own stored growth hormone. That is a meaningfully different proposition from injecting somatropin: the pituitary remains the regulator, the release stays pulsatile, and negative feedback through somatostatin and IGF-1 continues to operate. The practical consequence is a ceiling on how far it can push GH, which is a limitation and a safety characteristic at the same time.
Sermorelin held a US medicines licence for many years as Geref, used in the diagnostic assessment of pituitary function and in paediatric growth hormone deficiency. It was withdrawn from that market for commercial reasons rather than on safety grounds, which is an unusual position for a compound in this category.
The pen format
At 15mg this is one of the larger single compound pens in the range, which matters because sermorelin has a short half life and the protocols in the literature are frequent rather than sparse. 30 full 500mcg draws come out of one pen.
- 15.00mg of Sermorelin 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 Sermorelin 15mg pre-filled injection pen
- 4 × sealed pen tips, 32G 0.23 x 4mm
- Serialised, QR coded retail carton
Choosing between Sermorelin, Tesamorelin and the GHRPs
Sermorelin and tesamorelin are both GHRH analogues acting at the same receptor. Tesamorelin is the stabilised version, carrying a trans-3-hexenoyl group that resists the enzyme which degrades sermorelin within minutes, so it lasts longer and hits harder. It also holds a current medicines licence for visceral fat in HIV lipodystrophy, which sermorelin does not. Tesamorelin is the stronger and better evidenced of the two; sermorelin is the gentler and cheaper, with the pituitary kept more firmly in charge.
The GHRP compounds and ipamorelin are not alternatives to either. They act at the ghrelin receptor, a separate pathway, and the reason a GHRH analogue plus a GHRP is such a common pairing is that the two mechanisms combine rather than duplicate.

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 .
