Highlights from this day
  • step_one_sian — why does everyone talk about 7.5 and not 10 20:34
  • reship_rita — anyone tracked whether the GI difference held at the top doses 20:42
  • bp_down_bex — went back to semaglutide after 14 months because the cost difference mattered more than the GI 21:50
  • courier_vs_post — the 40 vial in 1.5ml gives 4mg/ml which puts 7.5 on 15 units, nice round numbers plateaued at 24 weeks the same way i did on semaglutide, so i doubt its compound… 22:20
CV

plateaued at 3 weeks the same way i did on semaglutide, so i doubt its compound specific

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

whats the plateau pattern here, same as semaglutide or different

🔥5😂7

*Medutest not the other one

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

LM

the 2.5 to 5 step was the roughest one for me and everything after was easier
went back to semaglutide after 23 months because the cost difference mattered more than the GI

LM

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

CV

i sat at 7.5 for 2 months and never needed more, which is where the folklore comes from

LM

changed my mind about needing 15, i was chasing a number rather than an outcome, anyway
dual agonist, GIP as well as GLP-1, thats the whole difference in one line

YV

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

TT

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

how did people handle the 2.5 to 5 jump

LO

slightly off topic but my Medutest result on a MKM vial came in at 96.8 which is why i keep buying from them, your mileage will differ

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

YV

coming back to this is SURMOUNT-OSA the sleep apnoea one

Cited study
Tirzepatide versus Semaglutide Once Weekly in Type 2 Diabetes (SURPASS-2)
New England Journal of Medicine · 2021
The head-to-head everyone quotes. Note the semaglutide comparator dose.
TT

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

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

YV

did going from 2 semaglutide to 5 of this feel like a step down for anyone

BR

anyone got a 4 recon they like for the 40 vials
went back to semaglutide after 19 months because the cost difference mattered more than the GI

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

5 did nothing

BD

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

YV

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

🤝10
BD

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

VB

Testing queue: 5 submissions open, 115 awaiting dispatch.

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

SO

why does everyone talk about 7.5 and not 10

PN

how many weeks at 7.5 before you knew it was enough

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)
SO

does the GIP arm actually explain the easier nausea or is that hand waving
£72 for a 5 vial is roughly what ive paid for the last year

SF

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

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

coming off semaglutide, is there a conversion or do i restart at 2.5

BD

went back to semaglutide after 14 months because the cost difference mattered more than the GI

SURMOUNT is weight

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

🧪15

the 40 vial in 1.5ml gives 4mg/ml which puts 7.5 on 15 units, nice round numbers
plateaued at 24 weeks the same way i did on semaglutide, so i doubt its compound specific

📉3🎉12

did anybody switch back to semaglutide after trying this

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