Highlights from this day
  • sorrel_sends — anyone stopped at 10 and stayed there for months 05:55
  • appetite_back — the trials titrated every four weeks to a target, most people here stop at whatever works 06:45
  • lot_number_lou — the switch felt like a step down at first and then caught up around week 21 07:46
  • spreadsheet_stu — my Janoshik result on a CPC vial came in at 98.1 which is why i keep buying from them 08:57
CC

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

40 units of a 2.5 solution is a lot of volume and i check that one twice every single time, still working it out

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

*Medutest not the other one

CC

went back to semaglutide after 11 months because the cost difference mattered more than the GI

CC

back after 22 months, do i restart at 2.5 or pick up near where i left off

SS

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

SS

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

no clean conversion

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)
CS

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

switched last year

12 did nothing extra over 10 for me and that still holds a year later, ask me again in a month

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

quick one i sat at 7.5 for 24 months and never needed more, which is where the folklore comes from

anyone got a 4 recon they like for the 2 vials

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

SS

£55 for a 15 vial is roughly what ive paid for the last year, i could be wrong

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

SS

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

72 weeks, tirzepatide 5, 10 and 15mg against placebo.

titrate slow

SS

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

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

AB

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

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)

folklore probably

ok so held 10 for 19 months and lost 22kg over that stretch, slow and boring and fine

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

plateaued at 20 weeks the same way i did on semaglutide, so i doubt its compound specific, thats just me

the switch felt like a step down at first and then caught up around week 21

AB

switched from 15 semaglutide and started at 2.5, took the slow route, never regretted it

AB

the 5 vial in 3ml gives 2mg/ml which puts 0.25 on 30 units, nice round numbers, ymmv

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

is the 30 vial the common one or do people use 20

restarted at 2.5 after 14 months off and the first two doses reminded me why titration exists, not advice obviously

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

GB

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

GB

i argued the sweet spot was nonsense and then spent 21 months at 7.5 not needing more
