The hallmarks of aging are a set of interconnected biological processes that researchers use to describe why we age at the cellular level. They include telomere shortening, DNA damage, cellular senescence, mitochondrial decline, and loss of protein and cellular cleanup, among others.
A framework for aging
In an influential set of papers, biologists grouped the messy biology of aging into a manageable list of hallmarks. The value of the framework is that each hallmark is measurable and, in principle, targetable. If aging is not one thing but a handful of interacting processes, then studying each one gives research a clear focus.
The main hallmarks
The commonly cited hallmarks include:
- DNA damage that accumulates over time.
- Telomere shortening with each cell division.
- Cellular senescence, the buildup of "zombie" cells.
- Mitochondrial decline, reducing cellular energy.
- Loss of proteostasis, as autophagy and repair slow down.
- Deregulated nutrient sensing, tied to metabolism and NAD+.

Peptides are one of the most studied frontiers in the optimization space. Every Axis compound is third-party tested to 99.4%+ purity with a certificate of analysis on every batch.
Why the framework matters
The hallmarks explain why longevity research targets so many different levers at once, from senolytics to metabolic health to mitochondrial support. They also connect the everyday and the experimental: fitness, sleep, and nutrition influence several hallmarks, while compounds studied in the lab target others. This is a research framework, not a menu of treatments.
Key takeaways
- The hallmarks of aging are interconnected processes that explain why we age.
- They include DNA damage, telomere loss, senescence, and mitochondrial decline.
- The framework makes aging measurable and targetable.
- Lifestyle and research both influence different hallmarks.
A note on research use
The peptides supplied by Axis Peptide Labs are reference compounds for laboratory and research use only. They are intended for qualified researchers working in academic, institutional, and analytical settings. They are not drugs, foods, cosmetics, or medical products, and they are not intended for human or veterinary consumption. Documented identity and documented purity are what matter most when sourcing a compound, both of which are published on the Axis certificates of analysis page.
