Highlights from this day
  • lisbon_lot — the sweet spot argument is really about effect per side effect, not a magic number 11:01
  • spreadsheet_stu — licensed top is 15 weekly, past that is not a licensed dose and nobody here can tell you what it does 13:14
  • thank_you_year_on — switched last year, still working it out 14:34
  • quill_questions — SURMOUNT-OSA was the sleep apnoea trial and it is not a weight headline however its quoted 18:06

my Janoshik result on a FGP vial came in at 99.2 which is why i keep buying from them

40 units of a 2 solution is a lot of volume and i check that one twice every single time

anyone tracked whether the GI difference held at the top doses

MM

held 10 for 24 months and lost 12kg over that stretch, slow and boring and fine

MM

€55 for a 10 vial is roughly what ive paid for the last year

10 was enough

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

QH

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

LL

slightly off topic but anyone got a 2.5 recon they like for the 15 vials

LL

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

LL

plateaued at 8 weeks the same way i did on semaglutide, so i doubt its compound specific

LL

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

LL

the switch felt like a step down at first and then caught up around week 32

how did people handle the 2.5 to 5 jump

LL

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)

SURMOUNT is weight

WT

coming back to this 12 did nothing extra over 10 for me and that still holds a year later

QH

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

QH

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

SC

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

at 2.5 my appetite went completely and i dropped back a step, eating nothing isnt a win

WW

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

WW

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

is the sweet spot argument about effect or about side effects

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

easier gi for me

QQ

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

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

why does everyone talk about 7.5 and not 10
i log everything and my appetite curve looks flatter across the week than my semaglutide log did

SS

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

SS

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

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

GG

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

5 did nothing

no clean conversion

VB

Reminder for thank_you_year_on: dose day is today. Set 5 days ago.

FF

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

WW

restarted at 2.5 after 4 months off and the first two doses reminded me why titration exists

💀1

follow up same plateau here

went back to semaglutide after 20 months because the cost difference mattered more than the GI

TY

switched from 2 semaglutide and started at 2.5, took the slow route, never regretted it

titrate slow

PB

folklore probably, not advice obviously
GI was noticeably easier for me than semaglutide at what felt like the same appetite effect

PB

ok so i sat at 7.5 for 14 months and never needed more, which is where the folklore comes from

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

QQ

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