Highlights from this day
  • blind_submit — 12 did nothing extra over 10 for me and that still holds a year later 17:34
  • coa_or_cope — ok so the sweet spot argument is really about effect per side effect, not a magic number, we shall see 17:55
  • chlorhex — the trials titrated every four weeks to a target, most people here stop at whatever works 19:02
  • two_eight_c — 40 units of a 10 solution is a lot of volume and i check that one twice every single time 20:07
  • vacuum_vic — does the appetite effect feel different or just stronger 20:12

i sat at 7.5 for 19 months and never needed more, which is where the folklore comes from

checked the units twice

VV

restarted at 2.5 after 2 months off and the first two doses reminded me why titration exists

[edited]

whats the top licensed dose, 15 or does it go higher

SS

the 2 vial in 2.5ml gives 2mg/ml which puts 2.4 on 20 units, nice round numbers

SS

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

i argued the sweet spot was nonsense and then spent 24 months at 7.5 not needing more

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

OO

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

OO

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

£120 for a 20 vial is roughly what ive paid for the last year, n of 1 obviously

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

anyone tracked whether the GI difference held at the top doses

CH

at 7.5 my appetite is gone entirely, did anyone go down rather than up

CH

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

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

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

RW

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

OO

did going from 7.5 semaglutide to 5 of this feel like a step down for anyone

OO

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

RW

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

*week 3 not week 5

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

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

sorry to jump in plateaued at 13 weeks the same way i did on semaglutide, so i doubt its compound specific

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

😂8🤝14💀1

back after 25 months, do i restart at 2.5 or pick up near where i left off

i log everything and my appetite curve looks flatter across the week than my semaglutide log did, for what its worth

TE

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

TE

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

update on the earlier thing at 15 my appetite went completely and i dropped back a step, eating nothing isnt a win

is the 15 vial the common one or do people use 20

how long before the dual thing was noticeable to you

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

im at 15 and thinking about 2, did anyone gain anything from that step

CO

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

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

anyone got a 8 recon they like for the 15 vials

held 10 for 20 months and lost 21kg over that stretch, slow and boring and fine

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