First you observe some symptoms that clearly tell you that the therapy is going well
From a scientific standpoint, GHK-Cu remains the better-validated compound
They demonstrated that BH4 determines the sensitivity of CRC cells to erastin-induced ferroptosis
So when you're looking at labels, it's more often the packaged foods, which I think that's where a lot of the issues come in
Our roGFP2 measurements confirm (i) that dynamic roGFP2 sensing (or the physiological glutathionylation/deglutathionylation of regular surface-exposed cysteinyl residues) requires a glutaredoxin activity, and (ii) that glutathionylated proteins or metabolites should be very transient redox species when GSH and glutaredoxins are present (unless they are stabilized by a kinetic uncoupling mechanism) 5,32,34,35,61,62,63,64
