Peptides for Detox & Cellular Cleansing Research

Glutathione is the primary cofactor for Phase II liver detoxification — the process by which the liver conjugates (attaches) toxins to water-soluble molecules for excretion via bile and urine. Without adequate Glutathione, the liver cannot efficiently process environmental pollutants, drug metabolites, heavy metals, or endogenous waste products like lipid peroxides. Glutathione also directly neutralises free radicals and reactive oxygen species, preventing oxidative damage to cell membranes, DNA, and proteins. Peptides Pharma's vial-delivered Glutathione provides near-complete bioavailability, bypassing the digestive degradation that limits oral Glutathione supplements.

NAD+ supports cellular detoxification through several mechanisms. It fuels sirtuins — enzymes that regulate autophagy (the cell's self-cleaning process that removes damaged organelles and misfolded proteins). NAD+ also powers PARP enzymes involved in DNA repair, preventing the accumulation of genetic damage from toxin exposure. At the mitochondrial level, adequate NAD+ ensures efficient energy production with minimal electron leakage, reducing the generation of reactive oxygen species at their source. Together, NAD+ and Glutathione address both the production and elimination of cellular waste.

Oral Glutathione is extensively degraded by digestive enzymes and gastric acid, with studies showing bioavailability as low as 3-5%. This means over 95% of oral Glutathione never reaches the bloodstream in active form. Peptides Pharma's vial-delivered Glutathione bypasses the entire gastrointestinal tract, providing near-complete bioavailability at a fraction of the dose required for oral supplementation. Similarly, NAD+ taken orally must be converted through multiple enzymatic steps (NR to NMN to NAD+), with significant losses at each stage. Direct NAD+ delivery via Peptides Pharma's vial system ensures the active coenzyme reaches cells intact.

The liver is the body's primary detoxification organ and has the highest concentration of Glutathione of any tissue. Chronic toxin exposure, alcohol, medications, and environmental pollutants deplete hepatic Glutathione stores, impairing the liver's ability to process and eliminate harmful compounds. Research shows that maintaining adequate Glutathione levels supports hepatocyte (liver cell) viability, reduces oxidative damage to liver tissue, and preserves the function of cytochrome P450 enzymes essential for drug metabolism. NAD+ further supports liver function by powering the metabolic processes that regenerate hepatocytes and maintain liver tissue integrity.
