[Question] SURMOUNT — what am I missing here

Questionbranch of 20 comments

SURMOUNT — what am I missing here. If this has been answered properly somewhere, link me and I will delete. Research-use-only material is not approved for human use. Anything in this thread about how a research vial "should" titrate is a discussion about chemistry, not a plan. SURMOUNT-1 ran 72 weeks with the top arm…

Went 10 to 12.5 on the calendar and had the worst fortnight of the whole run. Dropped back to 10 and everything settled.

What step are you on and how long have you been there?

2.5 is the starter dose and it is not meant to be the dose that works

SURMOUNT-1 landed around 21% at 72 weeks on the top arm

the appetite effect is blunter than sema, in a good way, most weeks

Does food noise follow the day after the shot, or is it spread across the week?

Sulphur burps for the first eight days after each step, then nothing. Predictable enough that I planned my week around it.

the trials titrated on a calendar, real people titrate on symptoms

Weekly dosing again, half-life in the same neighbourhood as sema, so a step change takes about a month to reach steady state. Judging a new step at day five is judging noise.

Which week did the appetite change actually land for you?

u/incretin_ivypharmacology63 points·1 year ago

Cosigning the four-week thing. It is a minimum interval, and treating it as a schedule to keep up with is how people end up miserable at 12.5.

hold the dose that works, the ladder is not a leaderboard

Came off sema and onto tirz with a two-week gap. The first month was flat and I assumed I had made a mistake. Month two it moved.

Correction to my own post above — I said 10mg and I have been on 2.5mg since the spring. Same argument, wrong number.

u/amara_halonen186 points·1 year ago

Week 24 was the first time the scale moved after a five-week stall. I changed nothing in that window.

u/blunt_coldbox29172 points·1 year ago

2.5mg is a four-week starting dose, not a maintenance dose. Worth being precise since people search these threads.

Agree. The GIP component is the interesting half and it barely gets discussed outside c/glp1science.

The distribution matters more than the mean. In the trial population the interquartile spread was wide enough that two honest people can have completely different runs on the same arm.

That percentage is body weight change, not body fat. Different measurement, and the distinction gets lost every time.

18kg over 60 weeks, never went past 10mg, and injection-site soreness stayed mild the whole way. Posting because the loud threads are all 15mg.

About c/tirzepatide

Tirzepatide-specific discussion: the dual-agonist pharmacology, the 2.5 → 15mg ladder, the appetite profile people describe as different from semaglutide, and the SURMOUNT/SURPASS trial programme. Comparisons with semaglutide are welcome as long as they are specific about dose equivalence being unknown.

c/tirzepatide rules
  1. "Tirz is better than sema" needs a comparator dose or it is a vibe, not a claim.
  2. Vial-splitting and self-compounding discussion stays in c/reconstitution.
  3. No pen-cracking tutorials. Discussing that people do it is fine; instructions are not.
  4. Independent community. Nobody here sells anything, and anyone who tries is banned.
  5. Not medical advice. Describe what you did; never prescribe to a stranger.
  6. Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
  7. No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
  8. No contact handles, wallet addresses or tracking numbers — they identify people.
  9. Be recognisably decent. Disagree hard, insult nobody.
