It has more to do with brain signals associated with GLP-1 use than any active dysfunction
From a molecular point of view, the necroptosis pathway is initiated by auto- and trans-phosphorylation of RIPK1 and RIPK3 at Ser-227, resulting in stimulation of their kinase activity and assembly of a heterodimer protein complex termed necrosome via their RIPK homotypic interaction motif domains (Oliveira et al., 2018

The consequences of these modifications are that IGF-1 LR3 retains the pharmacological activity of IGF-1 as an agonist of the IGF-1 receptor, has very low affinity for the insulin-like growth factor-binding proteins (IGFBPs), and has improved metabolic stability resulting in approximately three times greater potency than IGF-1, with a significantly longer half-life of about 2030 hours relative to IGF-1s half-life of about 1215 hours
