TT

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

TT

no gap when i switched, took the last semaglutide dose and started this a week later

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

📉8👀4

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

SS

anyone tracked whether the GI difference held at the top doses

AA

i sat at 7.5 for 24 months and never needed more, which is where the folklore comes from

SS

the GI difference held for me right up to 15, which isnt what a couple of people here found

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)

€185 for a 2 vial is roughly what ive paid for the last year

SURMOUNT is weight

GG

SURMOUNT was the weight programme and SURPASS was diabetes, thats the split people mix up, still working it out

RR

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

ok so the switch felt like a step down at first and then caught up around week 29

licensed top is 15 weekly, past that is not a licensed dose and nobody here can tell you what it does
the 2.5 to 5 step was the roughest one for me and everything after was easier

GG

i went to 15 and came back to 10, more suppression wasnt more useful for me

PS

40 units of a 10 solution is a lot of volume and i check that one twice every single time, thats just me

HH

quick one switched from 0.5 semaglutide and started at 2.5, took the slow route, never regretted it

HH

went back to semaglutide after 3 months because the cost difference mattered more than the GI

HH

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

HH

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

while im here does the appetite effect feel different or just stronger

start low anyway

[edited]

5 did nothing

SS

at 0.25 my appetite is gone entirely, did anyone go down rather than up

CS

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

[edited]
SS

slightly off topic but restarted at 2.5 after 8 months off and the first two doses reminded me why titration exists

at 10 my appetite went completely and i dropped back a step, eating nothing isnt a win

how long before the dual thing was noticeable to you

anyone got a 2 recon they like for the 10 vials

7.5 gang

titrate slow

GG

does the GIP arm actually explain the easier nausea or is that hand waving

GG

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

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

🎉3

*week 31 not week 4

checked the units twice

PT

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

PT

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

CS

there is no clean conversion between the two, anyone giving you a ratio is guessing

CS

at 15 the GI came back for me, so my easier profile claim only applies below that

1🎉3

switched last year

same plateau here

CS

held 10 for 10 months and lost 43kg over that stretch, slow and boring and fine

📉8🧪1

anyone stopped at 10 and stayed there for months

SS

coming off semaglutide, is there a conversion or do i restart at 2.5

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

is SURMOUNT-OSA the sleep apnoea one

while im here did going from 5 semaglutide to 5 of this feel like a step down for anyone
