During the first seven days following your initial injection, the changes are often more subtle than dramatic, but they signal that the medication is beginning to interact with your metabolic pathways
However, understanding VLDL requires context from other metabolic markers including triglycerides (which directly determine calculated VLDL), HDL and LDL cholesterol, insulin and glucose for assessing insulin resistance, liver enzymes (ALT, AST) to evaluate fatty liver, and inflammatory markers like hs-CRP
It functions as an agonist at the GLP-1, GIP, and glucagon receptors with activity across all three targets
