For the heart. For the years.
Veterinarian-directed rapamycin therapy. In cats, studied for slowing the heart-muscle thickening of HCM; in dogs, aimed at the effects of aging — lowering the chronic inflammation that comes with it. Dosed to your animal, reviewed by licensed veterinarians, delivered to your door.
One molecule, two different stories.
For cats
What it is used for
- Heart (HCM): slowing the thickening of the heart muscle — the strongest evidence, and the first FDA conditionally approved use
- Kidneys: mTOR research in chronic kidney disease, currently in clinical trials
- Healthy aging: a weekly protocol aimed at the biology of getting older
Prescription medicine — every order starts with a veterinary review, and unsuitable animals are declined and refunded.

What it is used for
- Healthy lifespan: the question the NIH-funded TRIAD trial is testing now

The pet they thought they’d lost.
Real words from Rapavie members. Individual experiences vary — these are their stories, not medical claims.
Miso is 14 and honestly moves like she did at 8. The vet check-ins make me feel like we’re doing this properly.
Our senior lab has more energy on walks and his bloodwork has never looked better. Wish we had started sooner.
The onboarding was so thorough — real vets, real answers. Pamuk approves of the therapy too.
Our 15-year-old poodle is stealing socks again. I only wish someone had told us this existed two years ago.
Sisu was diagnosed with early HCM. Between our cardiologist and the Rapavie vets, we finally feel like we are doing something instead of waiting.
What sold me was the honesty. They were clear that it is a prescription medicine reviewed by a vet, not a supplement. That is exactly why I trust it.
Individual results vary. These are members’ own experiences, not medical claims or expected outcomes.
The best time to start was years ago. The second best is now.
