Highlights from this day
  • deadspace — the sweet spot argument is really about effect per side effect, not a magic number 21:59
  • chlorhex — is SURMOUNT-OSA the sleep apnoea one 23:14
  • septum_sal — i argued the sweet spot was nonsense and then spent 22 months at 7.5 not needing more 23:41

update on the earlier thing the switch felt like a step down at first and then caught up around week 8

YV

at 1.7 my appetite is gone entirely, did anyone go down rather than up

DE

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

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)

checked the units twice

unrelated but held 10 for 18 months and lost 8kg over that stretch, slow and boring and fine

AD

at 15 my appetite went completely and i dropped back a step, eating nothing isnt a win

VV

genuine question the trials titrated every four weeks to a target, most people here stop at whatever works, still working it out

whats the plateau pattern here, same as semaglutide or different

5 did nothing

VV

5 was where i first noticed it properly, 2.5 did almost nothing for me

AD

12 did nothing extra over 10 for me and that still holds a year later, happy to be corrected

SS

GI was noticeably easier for me than semaglutide at what felt like the same appetite effect

DE

is there a reason to titrate slower than the four week schedule
SURMOUNT was the weight programme and SURPASS was diabetes, thats the split people mix up

right so the GIP explanation for easier nausea is plausible and i still treat it as a story not a fact

RT

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

DE

dual agonist, GIP as well as GLP-1, thats the whole difference in one line

did anybody switch back to semaglutide after trying this

SURMOUNT is weight

went back to semaglutide after 18 months because the cost difference mattered more than the GI

RT

the two compounds arent interchangeable week for week even if the effect ends up similar

VV

for the archive SURMOUNT-OSA was the sleep apnoea trial and it is not a weight headline however its quoted

for the archive 40 units of a 8 solution is a lot of volume and i check that one twice every single time

KK

the 2.5 to 5 step was the roughest one for me and everything after was easier

CH

the 40 vial in 1.5ml gives 5mg/ml which puts 0.25 on 20 units, nice round numbers

anyone tracked whether the GI difference held at the top doses

is SURMOUNT-OSA the sleep apnoea one

update on the earlier thing licensed top is 15 weekly, past that is not a licensed dose and nobody here can tell you what it does

KF

plateaued at 23 weeks the same way i did on semaglutide, so i doubt its compound specific

SS

i sat at 7.5 for 25 months and never needed more, which is where the folklore comes from

SS

if youre coming off semaglutide the honest answer is start low and find out, theres no table, for what its worth

SURMOUNT-1 versus SURPASS-2, which one was the weight trial

YV

genuine question switched from 1.7 semaglutide and started at 2.5, took the slow route, never regretted it, we shall see
