Structure, catalytic mechanism, and evolution of the glutathione transferases
The result is a 16-amino acid peptide that stimulates lipolysis through beta-3 adrenergic receptors on fat cells, without triggering IGF-1 elevation, insulin resistance, or the growth-promoting effects that make full HGH problematic for long-term metabolic use
Next, we will summarize some promising medicine monomers that activate the GSH system based on the categories of natural medicines, including flavonoids, terpenoids, phenolic acids, quinones, and alkaloids (Table 2, Supplementary Table S2)
Delivery method matters: subcutaneous (injectable) glutathione and nasal sprays bypass digestion, which may support better absorption than oral glutathione
