Medicine advocates caution, as a few peptides continue to possess unidentified hazards and long-term effects
Glutathione is a tripeptide produced by the liver, consisting of -l-glutamyl-l-cysteinyl-glycine
Because GHK-Cu is still being studied, its long-term effects are not fully known yet, so patch testing is always recommended before regular use
For a broader introduction to how peptides function in the body at the cellular level, Meto's How Peptides Work in the Body: Cell Signaling, cAMP & Healing Science covers the signalling biochemistry in accessible detail

For both of these final limitations, the use of rich multimodal clinical data such as clinical notes to assess patient-level features driving motivation for GLP-1 use and discontinuation, as well as imaging to quantify and assess fat loss through CT scans could help shed light on the true impact of GLP-1s on body composition as well as patient profiles that are related to varying levels of treatment effect
