Define 'effective'? Been on peptides for weeks now, just added cartalax a month ago. low back pain is way better—not sure if it's this one or something else, but I'll take it either way.
Oh no, that's such a great problem to have but also genuinely annoying! I did the same thing - waited forever to buy anything new, then finally caved and got a bunch of stuff at one size and now it's all too big. At this point I'm doing thrift store rotation until things actually stabilize.
The feeling-the-same-inside while people treat you differently outside is the body image adjustment that lags the actual change. 27kg down and still seeing the old self is really common and tends to correct over time but rarely on the same schedule as the physical change. Small external anchors like a specific outfit start to shift the internal picture over time.
I've been burned by that twice - bought a whole wardrobe and kept shrinking out of it. Down 130 is incredible though, that's not a small number. Finally hit 5k pace last month which meant I needed a completely different set of clothes for that too.
The loose skin question after 80 lbs is fair to ask - the practical answer depends on where the remaining fat versus true excess skin distinction falls. At goal weight and then 6-12 months stable, the picture becomes clearer and a surgical consultation is more informative.
