Research Peptides Directory

NAD+ is a critical molecule for cellular energy production and repair that declines with age. Supplementing NAD+ precursors may help improve energy levels, brain function, and slow aspects of aging.

Epitalon is an anti-aging peptide that may help slow cellular aging by activating telomerase, the enzyme that protects your DNA. It's one of the most studied longevity peptides.

MOTS-c is a mitochondrial peptide that may boost metabolism and mimic some of the benefits of exercise. It's being studied for its potential to improve energy, blood sugar control, and fat burning.

SS-31 (Elamipretide) is a mitochondrial peptide that may protect and restore cellular energy production. It's being studied for age-related diseases, heart failure, and conditions caused by mitochondrial dysfunction.

Glutathione is the body's most abundant antioxidant, a small peptide that cells build themselves from three amino acids. It plays a key role in three things: protecting cells from damage by unstable molecules called free radicals, powering the mitochondria that make cellular energy, and helping the liver clear out drugs and toxins. Intracellular levels decline naturally with age, and low levels are linked to chronic illness, fatigue, and slower recovery from stress. People take it as a supplement by mouth (usually in a liposomal liquid for better absorption), through an IV at clinics, sprayed in the nose for brain-related research, or applied topically to the skin. Evidence supports real increases in measurable glutathione levels with supplementation, though the size of clinical effects varies by form, dose, and goal.

Humanin is a naturally occurring mitochondrial peptide that may protect cells from stress and age-related damage. It's being studied for its potential role in Alzheimer's disease, diabetes, and cardiovascular health.

FOXO4-DRI is a peptide designed to selectively remove old, damaged cells (called senescent cells) that build up in the body with age. These cells stop dividing but refuse to die, releasing harmful signals that damage surrounding healthy tissue. FOXO4-DRI works by disrupting a specific protein interaction that keeps these cells alive, allowing them to undergo natural cell death. In animal studies, this led to improved fur growth, kidney function, and overall fitness in aged mice. No human clinical trials have been conducted, and the peptide remains a preclinical research compound.
