update on the earlier thing how many weeks at 7.5 before you knew it was enough

same plateau here

is 7.5 really the sweet spot or is that just channel folklore

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

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

10 was enough

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

RO

did anyone go past 15 and was there any point to it

KF

plateaued at 11 weeks the same way i did on semaglutide, so i doubt its compound specific, anyway

DP

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

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

5 was where i first noticed it properly, 2.5 did almost nothing for me, your mileage will differ

back after 11 months, do i restart at 2.5 or pick up near where i left off

BB

£38 for a 30 vial is roughly what ive paid for the last year, ymmv

i sat at 7.5 for 3 months and never needed more, which is where the folklore comes from

switched from 2.5 semaglutide and started at 2.5, took the slow route, never regretted it, thats just me

im at 2.4 and thinking about 2.5, did anyone gain anything from that step

unrelated but does the appetite effect feel different or just stronger

at 2 my appetite is gone entirely, did anyone go down rather than up

MO

12 did nothing extra over 10 for me and that still holds a year later
the GI difference held for me right up to 15, which isnt what a couple of people here found

EM

unrelated but my VendorInvestigate result on a BCH vial came in at 99.4 which is why i keep buying from them

follow up held 10 for 12 months and lost 31kg over that stretch, slow and boring and fine
changed my mind about needing 15, i was chasing a number rather than an outcome

PP

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

⚠️14🧪5

no clean conversion

15 is the top

restarted at 2.5 after 13 months off and the first two doses reminded me why titration exists

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

[edited]

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

EM

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

PP

the sweet spot argument is really about effect per side effect, not a magic number, still working it out

for the archive switched last year, i have it written down somewhere

slightly off topic but did anyone find the GI easier than semaglutide at an equivalent effect
