Highlights from this day
  • meniscus_mel — licensed top is 15 weekly, past that is not a licensed dose and nobody here can tell you what it does 19:39
  • meniscus_mel — at 0.25 my appetite is gone entirely, did anyone go down rather than up 19:56
  • VialBot — Assay note: WWB lot B-0329 reported at 98.6% of label content. 20:51
  • cold_chain_cmdr — slightly off topic but i log everything and my appetite curve looks flatter across the week than my semaglutide log did 22:27

restarted at 2.5 after 25 months off and the first two doses reminded me why titration exists

how did people handle the 2.5 to 5 jump

MM

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

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)
GG

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

MM

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

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

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

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

🧪16⚠️6

no clean conversion

*Janoshik not the other one

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

💀7

switched from 12 semaglutide and started at 2.5, took the slow route, never regretted it

TT

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

why does everyone talk about 7.5 and not 10

FT

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

[edited]
FT

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

MM

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

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

👀5👍1📉7

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

The head-to-head everyone quotes. Note the semaglutide comparator dose.
GB

coming off semaglutide, is there a conversion or do i restart at 2.5
i argued the sweet spot was nonsense and then spent 14 months at 7.5 not needing more

did going from 1.7 semaglutide to 5 of this feel like a step down for anyone

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

[edited]

sorry to jump in 40 units of a 4 solution is a lot of volume and i check that one twice every single time

start low anyway

the 20 vial in 5ml gives 2.5mg/ml which puts 0.5 on 30 units, nice round numbers

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

at 2.4 my appetite went completely and i dropped back a step, eating nothing isnt a win

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

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

went back to semaglutide after 13 months because the cost difference mattered more than the GI

checked the units twice

is SURMOUNT-OSA the sleep apnoea one

SURMOUNT is weight

DT

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

5 did nothing

DT

did anyone find the GI easier than semaglutide at an equivalent effect

[edited]

GIP plus GLP-1

GB

quick one GI was noticeably easier for me than semaglutide at what felt like the same appetite effect
i argued the sweet spot was nonsense and then spent 26 months at 7.5 not needing more

GB

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

NP

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

[edited]

10 was enough

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

plateaued at 6 weeks the same way i did on semaglutide, so i doubt its compound specific

NT

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

NP

my Janoshik result on a WWB vial came in at 99 which is why i keep buying from them

BB

held 10 for 22 months and lost 17kg over that stretch, slow and boring and fine

switched last year

anyone got a 5 recon they like for the 10 vials

NP

how many weeks at 7.5 before you knew it was enough

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