Highlights from this day
  • vialkeeper — follow up anyone tracked whether the GI difference held at the top doses 13:50
  • karl_fischer — the two compounds arent interchangeable week for week even if the effect ends up similar 14:36
  • drawup_dee — i went to 15 and came back to 10, more suppression wasnt more useful for me 16:41
  • drawup_dee — plateaued at 13 weeks the same way i did on semaglutide, so i doubt its compound specific, from memory 16:43

the 15 vial in 3ml gives 2mg/ml which puts 7.5 on 50 units, nice round numbers

*Medutest not the other one

7.5 gang

VI

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

*Janoshik not the other one

for the archive is the sweet spot argument about effect or about side effects

coming off semaglutide, is there a conversion or do i restart at 2.5
at 15 the GI came back for me, so my easier profile claim only applies below that

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

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

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

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

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

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

VI

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

KF

restarted at 2.5 after 21 months off and the first two doses reminded me why titration exists

DD

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

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)

the switch felt like a step down at first and then caught up around week 23

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

12 did nothing extra over 10 for me and that still holds a year later
