Interestingly, among the proteins that showed increased phosphorylation, most of them were synaptic proteins associated with pre-synaptic short-term plasticity (e.g., Syn1, Rims1), post-synaptic density structure (e.g., scaffolding proteins, actin remodeling), glutamate receptors (e.g., Grin2b/5), or inhibition of translation (e.g., AMPK) (Wang et al., 2018)

It helps to believe in products that pay attention to the quality of their ingredients, and it does that here
Bottom line on safety: If someone considers peptide therapy, it should be under medical supervision with pre-treatment screening (baseline GH/IGF-I, metabolic panel, glucose), ongoing monitoring, and sourcing from reputable, traceable suppliers under a lawful framework
