Highlights from this day
  • vienna_vial — the GIP explanation for easier nausea is plausible and i still treat it as a story not a fact, anyway 14:03
  • snac_and_water — changed my mind about needing 15, i was chasing a number rather than an outcome, your mileage will differ 14:30
  • slow.taper — restarted at 2.5 after 16 months off and the first two doses reminded me why titration exists 14:45
  • point_two_five — 12 did nothing extra over 10 for me and that still holds a year later, not advice obviously 15:28
  • vienna_vial — held 10 for 16 months and lost 41kg over that stretch, slow and boring and fine 15:37

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

my VendorInvestigate result on a CPC vial came in at 98.6 which is why i keep buying from them

ok so is the 5 vial the common one or do people use 20
plateaued at 29 weeks the same way i did on semaglutide, so i doubt its compound specific

start low anyway

the two compounds arent interchangeable week for week even if the effect ends up similar, happy to be corrected

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

RR

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

😂8👍4🧪8

how long before the dual thing was noticeable to you

SA

back after 15 months, do i restart at 2.5 or pick up near where i left off

PT

did anybody switch back to semaglutide after trying this
at 15 the GI came back for me, so my easier profile claim only applies below that

ST

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

ST

SURMOUNT-OSA was the sleep apnoea trial and it is not a weight headline however its quoted
40 units of a 2.5 solution is a lot of volume and i check that one twice every single time

[edited]

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

VV

held 10 for 16 months and lost 41kg over that stretch, slow and boring and fine

the 40 vial in 3ml gives 8mg/ml which puts 15 on 10 units, nice round numbers

FI

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

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

RL

plateaued at 18 weeks the same way i did on semaglutide, so i doubt its compound specific

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

AHI as the primary endpoint, with and without PAP therapy.

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

TL

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

TL

the switch felt like a step down at first and then caught up around week 28

15 is the top
plateaued at 11 weeks the same way i did on semaglutide, so i doubt its compound specific

10 was enough

WW

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

went back to semaglutide after 9 months because the cost difference mattered more than the GI

TT

for the archive $55 for a 40 vial is roughly what ive paid for the last year

40 units of a 8 solution is a lot of volume and i check that one twice every single time

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

TT

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

switched from 2 semaglutide and started at 2.5, took the slow route, never regretted it

titrate slow

anyone stopped at 10 and stayed there for months

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

WW

quick one how did people handle the 2.5 to 5 jump

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)

at 1 my appetite is gone entirely, did anyone go down rather than up

👍2

anyone got a 10 recon they like for the 5 vials

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

WW

quick one im at 7.5 and thinking about 2, did anyone gain anything from that step

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

MC

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