3-week stall on compounded sema after a clean run, partitioning shift or am i missing something

asking before my next telehealth bc i’d rather walk in with a hypothesis than ‘it stopped working.’ the stall:

  • weeks 14-17: clean 0.9 lb/wk
  • last three: -0.2, +0.1, -0.1
  • week 18 now, compounded sema, no polysorbate 80, 0.5mg steady
  • down 22 lb from 204 confounders i’m aware of, want to be honest about: 1. added strength work at week 15. so some of what’s sitting on the scale is almost certainly glycogen and water in muscle that wasn’t there before. this is the one i keep coming back to. 2. tape is still moving. waist down a bit, hips a bit. not dramatic but the curve hasn’t flattened the way the scale has. that’s the partitioning-shift read. 3. food noise hasn’t returned. injection days 5-6 i still see protein intake tank 15-20g without trying. so it doesn’t read like trough-drift or tolerance, at least not the appetite side of it. what i’m leaning toward: lean preservation is showing up in the data and the scale is a bad instrument for what’s actually happening right now. the standard ‘give it 3 weeks’ advice is the thing i’d push back on a little, bc i’ve watched friends sit flat 5 weeks before tape caught up, and my own last stall was closer to 3.5. starting BMI seems to change that resolution window more than the rule admits. what i’m NOT going to do: titrate up just to chase the scale. dose isn’t the lever if appetite suppression is still working. that’s escalating to fix the wrong problem. what i’d actually want to check before the appt:
  • cycle phase. still cycling, fluid swing of 2-4 lb across the month is exactly the soft drift that mimics a stall
  • dose number within vial. compounded sema without polysorbate 80 has a different degradation curve than the pen stability data everyone quotes. late-vial doses are worth logging
  • protein floor in the 48hr post-shot window. holding 130g is the one lever i trust rn one thing that’s actually made the retrospective legible, the journal field tied to each food-noise score. a ‘4’ on day 3 reads completely different than a ‘4’ on peak suppression day, and the number alone won’t tell you that. been logging in careclinic and the notes are what made the pattern obvious, not the score. for anyone who’s sat through a stall like this on compounded: did the tape keep moving through it? and roughly how many weeks before the scale caught back up?

The thinking here is careful and the hypothesis is worth bringing to that appointment. But “lean preservation is showing up in the data” is doing a lot of work for three weeks post-strength-start. At that point you’re mostly measuring glycogen expansion and IM water, not actual lean accrual. Both produce the same tape-and-scale divergence but they resolve on different timelines. The fat loss may be running continuously; the mechanism is just harder to confirm this early.

The part I’d gently turn over is “both produce the same tape-and-scale divergence.” I’m not sure they do, and that’s the bit that matters for what I walk in with. Glycogen expansion and IM water sit almost entirely on the scale side. They add a pound or two of mass that the waist tape barely registers, because they’re not changing the cross-section anyone’s measuring with a soft tape around the navel. So the divergence I’m actually seeing, scale flat while waist and hips keep creeping down, doesn’t read as ambiguous between your two mechanisms. The tape moving is fat coming off the trunk. The glycogen-vs-lean-accrual question is real, but it lives on the scale side of the split, not inside the gap between the two instruments. Which, honestly, sharpens your point rather than fighting it. You’re right that “lean preservation is showing up in the data” is too strong for three weeks post-strength-start, and I’ll own that I reached. I can’t confirm lean accrual yet and probably won’t for a while. What I think I can say is narrower: fat loss looks like it’s still running, because the tape is the cleaner read of that right now and it hasn’t flattened. The timelines bit is the genuinely useful caution though. Glycogen tops out fast and then stops contributing to the scale, whereas real lean accrual is slow and ongoing. So if the scale is still stuck four or five weeks out with the tape still moving, the glycogen story has mostly expired and I’m looking at something else. When you watched the divergence resolve, did the scale catch up gradually or all at once after a flat stretch?

one thing the tape-vs-scale framing doesn’t touch: there’s decent evidence that adipocytes transiently fill with water as triglycerides are mobilized, so the tape can move while the scale stays put precisely because the cells aren’t fully emptied yet. the “all at once” drop you’re asking about is probably that release, not the fat loss itself, which was already happening. if that mechanism is running here, the scale catching up in a lump is actually more consistent with fat loss still running than a gradual slope would be. so “did it catch up gradually or all at once” might be the wrong diagnostic question, bc a sudden drop after a flat stretch isn’t a sign something changed, it’s a sign the lag resolved.
