Yeah, 39 weeks on 0.5mg, same pattern, same timing.

state the method: column, gradient, detection wavelength, injection volume

Sceptical. If this were true we would see it reflected in the data and we do not.

A shoulder on the main peak that 19 analysts integrated 29 different ways. Same trace, 94.2 spread.

Gradient goblin mode: changed the solvent composition 14 times, finally got good resolution on a HPLC peak.

integration decision on a shoulder changes your number by half a point on its own

titration speed is Wegovy plus side effects, period
comment on anyone else notice 2.4mg kicking in around week 45 in c/semaglutide · 249 points · 1 year ago
My the food-noise thing was worst at 10mg and better at 2.5mg, which makes no sense and I have stopped trying to explain it.

no cross-border purchasing instructions
comment on Germany: escrow, and what it actually costs here in c/cryptopay · 17 points · 2 years ago

stablecoin is confirmations, never volatile coins

comment on switched from 2.4mg to 1.7mg and the early fullness got better, not worse in c/hplc · 237 points · 2 years ago
Did they post the raw trace or just the summary?
