Highlights from this day
  • gall_bladder_gav — changed my mind about needing 15, i was chasing a number rather than an outcome 15:11
  • void_volume — whats the top licensed dose, 15 or does it go higher 15:14
  • tga_notice — is SURMOUNT-OSA the sleep apnoea one 17:40
  • belfast_bac — licensed top is 15 weekly, past that is not a licensed dose and nobody here can tell you what it does 19:01

at 15 the GI came back for me, so my easier profile claim only applies below that
SURMOUNT-OSA was the sleep apnoea trial and it is not a weight headline however its quoted

while im here i log everything and my appetite curve looks flatter across the week than my semaglutide log did

changed my mind about needing 15, i was chasing a number rather than an outcome

did anyone find the GI easier than semaglutide at an equivalent effect

VV

whats the top licensed dose, 15 or does it go higher

wk 1-4    2.5mg
wk 5-8    5.0mg
wk 9-20   7.5mg   <- stayed here
wk 21-24  10.0mg  (no extra benefit for me)
wk 25+    7.5mg   (came back down)

12 did nothing extra over 10 for me and that still holds a year later

RR

switched last year

The head-to-head everyone quotes. Note the semaglutide comparator dose.

went back to semaglutide after 15 months because the cost difference mattered more than the GI

[edited]

£72 for a 15 vial is roughly what ive paid for the last year

OO

anyone tracked whether the GI difference held at the top doses

folklore probably

VV

i argued the sweet spot was nonsense and then spent 19 months at 7.5 not needing more

TN

5 did nothing

does switching from semaglutide need a gap or do you just start

the sweet spot thing is survivorship, the people it worked for stayed and said so

the sweet spot argument is really about effect per side effect, not a magic number

SURMOUNT-OSA was the sleep apnoea trial and it is not a weight headline however its quoted, i think

anyone stopped at 10 and stayed there for months

BB

slightly off topic but the trials titrated every four weeks to a target, most people here stop at whatever works
