High-pH RP fractionation was performed at a flow rate of 0.6 mL/min with a gradient starting at 5% B for 2 min, increased to 50% B in 12 min, to 70% B within 0.5 min, and held for 6.5 min

This approach treats GHK-CU as a maintenance supplement rather than an intensive intervention

GPX1-4 and GPX6 use selenocysteine as the active center to catalyze the reduction of H 2 O 2 or organic hydroperoxides to water or corresponding alcohols, thereby reducing their toxicity and maintaining redox balance

28, 29 Certainly, the hypothesis of competition between GPxs 1, 3 and 4 for selenium incorporation needs to be investigated in detail in further clinical and experimental studies
