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.

GHRP-2 is a synthetic hexapeptide and one of the original growth hormone releasing peptides. It acts as an agonist at the ghrelin receptor, GHS-R1a, which is the same receptor the stomach hormone ghrelin uses to signal hunger and to trigger growth hormone release from the pituitary.
That mechanism puts it in a different class from the GHRH analogues such as sermorelin and tesamorelin. A GHRH analogue amplifies the signal the hypothalamus is already sending; a ghrelin receptor agonist pulls a separate lever, and also suppresses somatostatin, the brake that limits GH output. The two mechanisms are additive, which is why the literature so often pairs one of each rather than running two of the same type.
Compared with GHRP-6, GHRP-2 is the more potent of the pair for GH release and provokes noticeably less appetite stimulation. It does carry more cortisol and prolactin activity than the newer and more selective ipamorelin, which is the trade off that usually decides between them.
The pen format
GHRP protocols in the literature are small and frequent rather than large and occasional, which is exactly the pattern a syringe handles badly and a dial handles well. 200mcg is ten clicks.
- 6.00mg of GHRP-2 per pen, in solution and ready to use
- 1 unit = 20mcg. 10 units on the dial gives 200mcg
- 300 units in total, which works out at 30 full 200mcg 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 GHRP-2 6mg pre-filled injection pen
- 4 × sealed pen tips, 32G 0.23 x 4mm
- Serialised, QR coded retail carton
Choosing between GHRP-2, GHRP-6 and Ipamorelin
All three are ghrelin receptor agonists and all three release growth hormone. They differ in selectivity. GHRP-6 causes pronounced hunger, which is either the reason to pick it or the reason to avoid it. GHRP-2 releases more GH with much less of that appetite effect. Ipamorelin is the most selective of the three, with minimal cortisol and prolactin activity, at the cost of being the weakest GH releaser.
None of them is a replacement for a GHRH analogue such as sermorelin or tesamorelin. Those work through a different receptor, and the reason the pairing is so common in the literature is that the two mechanisms stack rather than overlap.

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 .
