Four Principles

Limits are not failures. They are the discipline.

01 / 04

Ethical Limits of Longevity Enhancement

Longevity science must never extend suffering, prolong pain, or mask decline for competition. The boundary is not what is technically possible — it is what is welfare-justified.

02 / 04

A Welfare-First Framework

Every protocol, biomarker decision and AI recommendation is bounded by the animal's welfare. Where performance and welfare conflict, welfare wins. There are no exceptions.

03 / 04

Performance vs Exploitation

Performance is acceptable; exploitation is not. The distinction sits in whether decline is being respected, recognised and acted upon — or hidden to extract more output.

04 / 04

Veterinary Oversight Principles

No longevity intervention applied to a managed animal is permissible outside veterinary judgment. The protocol is the structure; the veterinarian holds the authority.

Institutional Statement

“The animals we steward did not choose performance careers. They did not choose the workload, the schedule, or the science applied to them. Our institutional obligation is to make those choices on their behalf with restraint, transparency and an unyielding bias toward their wellbeing — even when it costs us performance, time or revenue.”

Practical Commitments

What this means in practice.

01

We do not publish, market or apply any intervention whose evidence base has not been openly stated.

02

We refuse to mask clinical decline through pharmacological or supplemental intervention.

03

We support — and protect — the veterinarian's authority to pause, modify or end any protocol.

04

We treat retirement as a clinical success, not a commercial failure.

05

We disclose conflicts of interest, funding sources, and limitations in every publication.

06

We measure ourselves by long-term healthspan outcomes — not short-term performance metrics.
