Glutathione is often used for its ability to support an even skin tone and a "bright" complexion
It promotes angiogenesis (the formation of new blood vessels), enhances growth hormone receptors, and modulates nitric oxide production
Toxic solvent residues DMF (dimethylformamide) Known liver toxin Associated with reproductive toxicity Must be removed to extremely low limits in GMP drugs DCM (dichloromethane / methylene chloride) Probable human carcinogen Central nervous system depressant Dangerous even in small amounts if injected TFA (trifluoroacetic acid) Corrosive Can remain in peptides as unmeasured TFA salt Pharmaceutical products often convert TFA salts to safer counterions Without validated HPLC, mass spectrometry, and residual solvent testing, patients may be injected with harmful chemical contaminants
Similarly, chelating agents like EDTA can bind copper ions, reducing the peptides efficacy
