I added this to a larger lab supply order so it qualified for free shipping. The package arrived on schedule, with clear labeling and no damage to the vial.

Common Questions

What is the connection between peptides and mitochondrial studies?

Mitochondria encode a small number of their own peptides in addition to nuclear-encoded proteins imported into the organelle. Peptides such as MOTS-c and Humanin are examples of mitochondrial-derived peptides (MDPs) that are studied as potential intracellular signaling molecules originating from the mitochondrial genome.

Additionally, some synthetic peptides — such as SS-31 — are designed to target mitochondrial membranes and interact with components of the electron transport chain environment. Together, these research threads make peptides a significant topic in mitochondrial biology investigations.

What are longevity peptides?

Longevity peptides is a research category grouping short peptides investigated in connection with cellular aging, mitochondrial function, telomere biology, and age-related changes in tissue signaling. Well-known examples studied in this space include Epitalon, MOTS-c, SS-31, and Humanin.

This is a broad and active area of biogerontology research. The peptides grouped here do not share a single biochemical family but rather a shared research focus on mechanisms relevant to aging biology. All products from Better Molecule in this category are lyophilized research materials intended solely for in vitro laboratory investigation.

How do longevity peptides relate to cellular aging research?

Cellular aging research examines processes such as mitochondrial dysfunction, telomere shortening, cellular senescence, chronic low-grade inflammation, and changes in gene expression over time. Longevity peptides enter this research as tools for probing specific pathways — for example, mitochondrial-derived peptides for mitochondrial stress responses, or pineal-associated peptides for studies of circadian and gene-expression regulation.

By using short, well-defined peptides, researchers can target individual mechanisms within the broader hallmarks-of-aging framework in a controlled manner. This makes longevity peptides useful experimental probes in mechanistic studies of biological aging.
