The Longevity Library
Start with what you notice at home
Explore the questions behind keeping them moving, keeping them strong, protecting their spark, and making more room for good days. Every article shows how strong the evidence is.
Keep them moving
Movement, mobility, and lasting capacity
Keep them strong
Body composition, food, and resilience
Protect their spark
Cognition, sleep, and familiar behavior
Understand the science
Evidence, peptides, TRIAD, and aging research
Research collections
Documented sections of the library
Longer-form collections sit alongside the articles below. Each states its evidence and regulatory context openly, including where evidence in dogs is still missing.
Peptide Science
Compound-by-compound documentation: what peptides are, why researchers are interested, and what has actually been studied in dogs.
- BPC-157
- TB-500 / Thymosin Beta-4
- GHK-Cu
- KPV
- Bioactive collagen peptides
- SS-31 / Elamipretide
- Selank & Semax
- Thymosin Alpha-1
Regulatory guide
Approved vs experimental
A plain-language guide to Librela, Cytopoint, Solensia, and why their regulatory status differs from research peptides.

Lifespan versus healthspan, the TRIAD trial, the Dog Aging Project, and how biological age differs from the number on a birthday. (Pawformance Labs is unaffiliated with TRIAD — see the disclosure on that page.)

What TRIAD Is Testing — and Why It Matters
The Test of Rapamycin in Aging Dogs is asking whether a drug that acts on a fundamental aging pathway can change how dogs age. Here is what the trial is actually measuring, and what researchers hope it will demonstrate.

Healthspan, Lifespan, and the Question TRIAD Asks
TRIAD is built on a simple but radical idea: that aging itself might be something we can study and eventually influence. Here is what that means for the years you get with your dog.

Rapamycin and mTOR: The Biology Behind TRIAD
Rapamycin targets a nutrient-sensing pathway called mTOR that appears again and again in aging research. Here is what that pathway does, why scientists are interested, and what is and is not known in dogs.

Protein and Muscle Maintenance in Ageing Dogs
Age-related muscle loss is common, consequential, and easy to miss under a coat. Maintaining muscle is a movement and nutrition problem together.

Sleep, Recovery and Cognitive Ageing
Sleep quality is one of the earliest observable signals of cognitive change in older dogs — and one of the easiest to support.

Breed, Size and the Pace of Ageing
Large dogs age faster than small dogs. That single fact should change how you time preventive care.

Designing a Week of Movement, Not Just Walks
Duration is the least interesting variable in canine exercise. Variety of surface, intensity and cognitive load does more for durability.

What Canine Healthspan Actually Means
Lifespan counts years. Healthspan counts the years a dog spends mobile, comfortable, curious and engaged. The difference is where owner decisions matter most.

Body Condition: The Single Most Controllable Variable
Of everything an owner controls day to day, keeping a dog at a lean body condition has the broadest and best-supported effect on long-term function.
