Cellular aging research has increasingly focused on a handful of pathways — chromosome protection, pineal gland signaling, and cellular energy metabolism — where specific compounds have shown research interest. Below is an overview of what’s being studied in this category.

Compounds and molecules commonly studied for longevity research

• Epithalon — A synthetic tetrapeptide studied for its proposed role in telomerase activation and telomere length regulation, with research interest rooted in its potential relationship to cellular senescence.
• Pinealon — A short synthetic peptide studied for its proposed role in supporting pineal gland function and neuroprotective signaling, particularly in aging-related research models.
• NAD+ (Nicotinamide Adenine Dinucleotide) — Worth noting up front: NAD+ is not a peptide — it’s a coenzyme found in every living cell, essential to energy metabolism. We carry it because it’s heavily studied alongside longevity-focused peptides for its role in mitochondrial function and cellular repair pathways, but we want to be accurate about what it actually is rather than blur the line.
• Humanin — A mitochondrial-derived peptide, one of the most heavily studied compounds in aging research specifically. Research in model organisms has linked humanin overexpression to extended lifespan, and human studies have found higher circulating humanin levels in centenarians and their offspring compared to age-matched controls.
• BPC-157 — Primarily studied for tissue repair (see our Building Muscle page), but also researched in the context of systemic regenerative capacity and gut-tissue integrity as they relate to healthy aging.
• TB-500 (Thymosin Beta-4) — Studied for its role in cell migration and regeneration broadly, with longevity-adjacent research interest in its relationship to tissue resilience and recovery capacity over time.

What the research generally focuses on

• Telomere biology and cellular senescence markers
• Pineal gland signaling and its downstream neuroprotective effects
• Cellular energy metabolism and mitochondrial function as they relate to aging
• Mitochondrial-derived peptides and their relationship to lifespan regulation Systemic tissue repair capacity as a marker of healthy aging
