  • nhs_pathway_nell — the GI difference held for me right up to 15, which isnt what a couple of people here found 17:20

held 10 for 6 months and lost 5kg over that stretch, slow and boring and fine

TW

quick one at 12 my appetite is gone entirely, did anyone go down rather than up

TW

is there a reason to titrate slower than the four week schedule

*week 9 not week 5

SURMOUNT is weight

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

📈1

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

TE

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

TE

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

switched from 15 semaglutide and started at 2.5, took the slow route, never regretted it

TE

plateaued at 26 weeks the same way i did on semaglutide, so i doubt its compound specific

TW

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

TE

genuine question im at 2.5 and thinking about 2, did anyone gain anything from that step

BF

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

i argued the sweet spot was nonsense and then spent 10 months at 7.5 not needing more, n of 1 obviously

BF

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

SURMOUNT was the weight programme and SURPASS was diabetes, thats the split people mix up

U1

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

U1

back after 20 months, do i restart at 2.5 or pick up near where i left off

start low anyway

for the archive i sat at 7.5 for 22 months and never needed more, which is where the folklore comes from

for the archive £72 for a 5 vial is roughly what ive paid for the last year

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

went back to semaglutide after 6 months because the cost difference mattered more than the GI, i have it written down somewhere

PS

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

U1

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

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

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

TE

the 2 vial in 0.5ml gives 8mg/ml which puts 1.7 on 30 units, nice round numbers

TE

whats the plateau pattern here, same as semaglutide or different

no clean conversion

U1

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

U1

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

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)

WN

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

5 did nothing

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

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

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

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

i argued the sweet spot was nonsense and then spent 18 months at 7.5 not needing more

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

WN

did going from 0.5 semaglutide to 5 of this feel like a step down for anyone

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