In addition, it should be taken into account that TCEP itself can suffer some decomposition in phosphate buffers at neutral pH ( AX Transformation Into DKP Implies a Loss of Reactivity and Antibacterial Potency DKP is a known metabolite of AX, considered to have lower or residual reactivity and bacteriostatic activity ( 1 H-NMR analysis of incubation mixtures containing equimolar amounts of DKP and butylamine revealed quantitative preservation of DKP (95% of the starting amount), thus confirming its lack of reactivity
However, a recent retrospective cohort study using a nationwide commercial administrative claims database including 6,806,046 patients with T2DM who underwent outpatient upper endoscopy from 2005 to 2021reported contrasting findings
Injectable GHK-Cu carries more risk , particularly for copper accumulation, if you have underlying conditions affecting copper metabolism (like Wilsons disease or chronic liver disease)
