Triglycerides dropped by half, HDL barely moved, and my calculated LDL is almost exactly where it started, which is not the outcome I had been promised.

What I am trying to establish is whether an unchanged LDL-C alongside a large triglyceride fall is a good result or a bad one, because ApoB and LDL-C seem to be telling different stories.

Not looking for reassurance. Looking for the part I have got wrong.

Taking the question as asked, rather than the general version of it. The glucagon component looks paradoxical and is not. Glucagon receptor agonism raises energy expenditure and drives hepatic fatty-acid oxidation, and its hyperglycaemic tendency is offset by the GLP-1 arm's insulin secretagogue effect. Net result: intake down from GLP-1/GIP, expenditure up from glucagon, glycaemia neutral or improved. It is a balancing act, and it is why the liver-fat results are the most interesting part of the dataset.

Fair, but phase 2 tolerability figures rarely survive contact with phase 3 scale. Triple agonism means three receptor systems generating adverse events, and the dropout column is the one I would read first when the larger trials report.

Adding a me-too, because a thread of one person's experience is not much use.

From the other side of the consultation, briefly.

Comprehensive lipid panel update relevant to the lipid panel:

MarkerBaseline6 Months12 MonthsReference
Total Cholesterol248213193<200
LDL163118113<100
HDL465155>40
Triglycerides228173113<150
LDL-P15281278928<1000

The triglyceride drop is the most impressive. My cardiologist reduced my statin dose based on these results.
