A new lease on life for your best friend

Every year, millions of dogs suffer quietly from stiff, aching joints, making it hard to walk, play, or even get comfortable at night.

For too long, the only answers have been daily pills that hide the pain or surgeries that come with real risks.

That's why we built ADStem™, the first licensed therapy of its kind in Europe. Instead of masking pain, it helps your dog's joints heal on their own.

One out of every five adult dogs struggles with stiff, aching joints that make it hard for them to run, play, or even get up to greet you. Most common treatments only cover up the pain for a little while, they don't actually fix what's really wrong inside your dog's joints. ADStem™ does.

Your dog's gentle, stress-free recovery.

Your dog's comfort comes first. The treatment journey is designed to be as gentle and stress-free as possible for both you and your best friend.

Gentle sedation.

A light, standard sedation keeps your dog calm and comfortable through the procedure.

§ 03 Stem cell 101

The science of a healing joint made simple.

Stem cells are your dog's own natural repair kit. They go straight to a sore joint, calm the inflammation, and signal the body to start healing itself.

By using healthy donor cells, ADStem™ delivers a powerful dose of healing, so your dog can move easily and comfortably for years.

Beyond the band-aid

Why healing beats hiding.

NSAIDs and pain pills can keep dogs comfortable in the short term, but the underlying damage continues. We treat the cause, not just the signal.

§ 04 Pet parent FAQ

Clear answers, for peace of mind.

Is ADStem™ safe for my dog?

Yes. ADStem™ meets the highest pharmaceutical safety standards and is backed by 5 years of follow-up data across 250+ dogs. There has been no measurable increase in chronic disease or other long-term risk in treated patients.

Which dogs can ADStem™ help?

ADStem™ has shown significant improvements across breeds and ages — for arthritis caused by old age, injury, or conditions a dog was born with. Whether your dog's arthritis is mild or severe, your vet can tell you whether ADStem™ is the right fit.

What does the treatment cost?

A single ADStem™ treatment is competitive with the cost of major joint surgery — and benefits can last up to five years. Your local vet will provide a personalised quote based on your dog and your region.

Will my dog need surgery to collect cells?

No. ADStem™ uses ethically sourced cells from healthy young donor dogs. Your dog only needs the single, gentle injection — no harvest surgery, no extra anaesthesia.

How quickly will I see a difference?

Most owners see meaningful changes — easier movement, better sleep, a return to favourite activities — within three to eight weeks of the single injection. Improvements typically continue to deepen over the first few months.
