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.

Tesamorelin is a synthetic analogue of growth hormone releasing hormone. The base molecule is the 44 amino acid human GHRH sequence, modified with a trans-3-hexenoyl group attached at one end. That single structural change is the whole point of the design: unmodified GHRH is broken down in the bloodstream within minutes, and the added group slows that degradation enough to make the molecule practical to work with.
Mechanistically it acts on GHRH receptors in the anterior pituitary, prompting the gland to release its own growth hormone rather than supplying growth hormone directly. That distinction matters in the literature, because release stays under the body's existing feedback control rather than bypassing it. Published research has focused on the resulting effects on IGF-1, and on visceral adipose tissue in particular, where phase 3 work reported preferential reduction of visceral fat with limited change in total body weight.
The pen format
This is where SerenQ does things differently. Instead of a lyophilised powder that has to be reconstituted, Tesamorelin arrives as a solution already loaded into a graduated injection pen with a dial and a dose window.
- 10mg of Tesamorelin per pen, in solution and ready to use
- 1 unit = 33.3mcg. 9 units on the dial gives 300mcg
- 300 units in total, which works out at 33 full 300mcg 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 Tesamorelin 10mg pre-filled injection pen
- 4 × sealed pen tips, 32G 0.23 x 4mm
- Serialised, QR coded retail carton
Tesamorelin against the other GH-pathway options
Tesamorelin is a stabilised GHRH analogue, so mechanically it sits on the same side as CJC-1295, it raises the ceiling of a growth hormone release rather than triggering one.
What separates it is the research attached to it. Tesamorelin is the GH-pathway compound with the most specific body-composition data, and that data centred on visceral adipose tissue, the fat around the organs rather than under the skin. No other compound in this category carries that.
If the interest is general GH pathway support, the Ipamorelin + CJC-1295 pen is the more common starting point and covers both halves of the mechanism. If the interest is specifically the visceral compartment, tesamorelin is the one with the evidence.
Worth being realistic: that research was conducted in a specific clinical population, not in lean trained individuals, and extrapolating between the two is where disappointment usually comes from.
