Quick answers

What does it cost?

$48 to $393 per box, depending on strength and supply. Shipping is $32 per order, shown before you pay. There is no subscription: you pay per box.

Which strength is right for my pet?

Strengths follow body weight — 0.4 mg: ≈ 1.3 kg (2.8 lb); 1.2 mg: ≈ 3.8 kg (8.4 lb); 2.4 mg: ≈ 7.7 kg (17 lb). Confirm the strength with your own veterinarian before starting.

Who should not use it?

It is not suitable for animals with diabetes or impaired glucose regulation, an active infection, significant liver disease, a planned surgery, or that are pregnant or nursing. Rapamycin can raise blood fats, so bloodwork before and during use matters. Talk to your veterinarian before starting.

How fast is delivery?

Every parcel ships tracked. Typical delivery once it ships: Europe 2–4 days, Türkiye 1–3 days, Gulf (GCC) 3–6 days, Rest of Asia 4–8 days, North America 4–8 days, Oceania 5–9 days.

Do I need a prescription?

It is a prescription medicine. Use it only under the guidance of your own veterinarian, and only where the law of your country allows it.

Can I return it?

If your box arrives damaged or wrong, we replace or refund it. In the EU and the UK you can withdraw within 14 days of delivery and return an unopened box; a box whose seal has been broken cannot be returned, for health-protection reasons.

The cat you love is worth fighting for

Aging in cats is not a mystery anymore. The biology behind heart disease, kidney decline and cancer risk runs through one central pathway — and rapamycin is the most studied molecule we have for targeting it.

Why rapamycin for cats

  • Heart — hypertrophic cardiomyopathy (HCM) is the most common heart disease in cats. Recent clinical research suggests rapamycin can slow its progression — a first for feline cardiology.
  • Kidneys — chronic kidney disease affects most senior cats. mTOR inhibition is under active clinical investigation at veterinary schools.
  • Cancer risk — documented benefit signals in feline mammary and squamous cell carcinomas.
  • Cellular aging — partial mTOR inhibition activates autophagy, the cell’s cleanup process, reducing systemic inflammation.

How the therapy works

One delayed-release, acid-resistant tablet once a week, with food. Dosing is calibrated to your cat’s body weight (0.4 mg, 1.2 mg or 2.4 mg strengths). Flavored oral suspensions — chicken, fish, beef — are available for cats that refuse tablets.

Guided by your own veterinarian

Rapamycin is a prescription medicine. Use it only under the guidance of your own veterinarian: go through your cat’s health history with them and confirm the dose and a monitoring plan before starting. Lab-tested to a 99.9% purity standard.

Rapavie and Rapamune are the same molecule, not the same medicine

Rapamune is the human transplant product. People find it when they search sirolimus, and the difference is worth a minute.
