Known in peptide research as a copper peptide complex, GHK-Cu remains a recognized compound in studies involving peptide structure, binding behavior, and broader biochemical investigation
The GST enzymes help neutralize them by attaching glutathione, allowing them to be cleared from the body
Coconut oil or a lightweight blend is preferable
Many other nonenzymatic glutathionylations according to mechanism (ii) probably also have such small rate constants 63,86
Can IV vitamin infusions replace a healthy diet
How to implement: Dosing: 20-40 grams daily (post-workout or as snack) Choose undenatured whey (cold-processed, preserves bioactive peptides) Whey protein isolate (higher protein content, lower lactose) Best sources: Grass-fed whey isolate : Highest cysteine content Undenatured whey concentrate : Preserves immunoglobulins and glutathione precursors Avoid heat-treated : Heat denatures cysteine Timing: Post-workout (supports muscle recovery + glutathione synthesis) Morning (with breakfast) For vegans: Pea protein isolate : Lower in cysteine but can be paired with NAC Hemp protein : Moderate cysteine content Evidence: A randomized trial found that 20 grams of whey protein daily for 3 months increased lymphocyte glutathione by 35% and improved immune markers in HIV patients [15]
