TB500 10mg in a pre-filled SerenQ injection pen. No reconstitution, no bacteriostatic water, no drawing up. Dial the units you need, read them off the window, done.
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.

TB500 is a synthetic fragment of Thymosin Beta-4, a protein of 43 amino acids found naturally throughout human tissue and present in high concentration at sites of injury. TB500 is not the whole protein. It is the short active region around the sequence LKKTETQ, the part that does the binding, isolated and produced synthetically because the fragment is smaller, more stable and far easier to work with than the full molecule.
That binding region is the reason it appears so often in the literature. Thymosin Beta-4 is the principal actin sequestering protein in most cells, meaning it controls the pool of building material available for the cytoskeleton. Research has examined how that influences cell migration, new blood vessel formation and the way tissue reorganises itself during repair, with animal studies looking at wound closure, corneal and cardiac models, and connective tissue.
The pen format
This is where SerenQ does things differently. Instead of a lyophilised powder that has to be reconstituted, TB500 arrives as a solution already loaded into a graduated injection pen with a dial and a dose window.
- 10mg of TB500 per pen, in solution and ready to use
- 1 unit = 50mcg. 10 units on the dial gives 500mcg
- 200 units in total, which works out at 20 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 TB500 10mg pre-filled injection pen
- 4 × sealed pen tips, 32G 0.23 x 4mm
- Serialised, QR coded retail carton
Choosing between TB500, BPC-157 and the Heal pen
TB500 is not thymosin beta-4, it reproduces the short active region of that protein rather than the whole thing, which is what makes it stable and affordable enough to be practical. Its proposed mechanism is actin regulation: repair depends on the right cells arriving, and actin is what governs cell movement.
That is a genuinely different route from BPC-157, whose research centres on gastrointestinal tissue and angiogenesis. Neither substitutes for the other, which is the whole reason the pairing exists.
TB500 is also the one usually described as acting systemically rather than locally, the usual justification for not injecting near the injury. Treat that as a reasonable proposition rather than a settled fact. If you intend to run both, the Heal pen holds them at a fixed ratio in one cartridge.
Guides that go deeper:
- TB500: a fragment, not thymosin beta-4
- BPC-157 and TB500: why they are run together
- Recovery peptides compared
