genuine question, not a gotcha. the before/after threads got me thinking about a thing nobody posting in them is actually measuring. a photo tells you the belly shrank. it tells you nothing about what the loss was made of. for women our age the variable that matters isn’t pounds gone, it’s the lean-to-fat ratio of those pounds, and a phone camera physically can’t see that. here’s the part I keep circling: tirz stacks GIP on top of GLP-1, and GIP activity in animal models shows some independent effect on fat vs lean partitioning that sema doesn’t replicate. so in theory the tirz crowd might be holding onto more muscle than the sema crowd at the same scale drop. whether that translates to humans is exactly the thing nobody has a DEXA baseline for, so the whole question stays invisible. you can’t read it off a mirror. rate of loss is the other half. someone dropping 40lb in four months on an aggressive ramp is almost certainly shedding muscle they’ll want back at 55, and the photo still reads as a clean win. not saying the drugs don’t work. saying the metric everyone’s celebrating is the one that hides the cost. anyone got a pre/post DEXA on either compound? that’s the thread I actually want to read.
