We started with one old dog and a lot of questions.

Our story

AminoTails began at a kitchen table in 2025^*, with a fourteen-year-old terrier named Pip and a stack of research papers on peptides that nobody in the pet aisle seemed to be reading.

The science was interesting. The products were not. Labels hid doses inside “proprietary blends,” nobody published test results, and the tablets were so unappealing that most of them ended up wrapped in cheese — or under the sofa.

So we built the company we wanted to buy from. Six peptides with a real body of research. Doses printed on the front, by weight. A certificate for every lot. And a chew that dogs and cats actually ask for.

We’re a small team of scientists, veterinary advisors^* and very opinionated pet owners. We’re not finished — the research isn’t either — but we’ll always show our work.

Four things we won’t compromise on.

They shape every formula, every label and every answer we give.

Show the science

Including the gaps. If the research is early, we say so — on the product page, not in the fine print.

Dose by weight

A five-pound cat and a ninety-pound shepherd shouldn’t get the same thing. Every formula comes with a clear chart.

Test every lot

Independent labs check identity, purity, content and contaminants before anything ships. Look up your lot any time.

Vets first

We design with veterinary input, and we’ll always tell you to check with yours before starting something new.

Made for the long walk.

We’re not chasing dramatic before-and-afters. We’re after more good years — more walks, more stairs, more mornings at the door. That takes consistency, honest dosing and a little patience.

No proprietary blends. Every peptide and amount is on the label.
No disease claims. Supplements support; your vet diagnoses and treats.
No mystery fillers. If it’s in the chew, we’ll tell you why.

The pack, so far.
