tirzepatide: the version I wish someone had shown me in week 1

Results Long Haul ×7 Clean Column ×2 Well Actually ×2

tirzepatide: the version I wish someone had shown me in week 1. This is a description of what happened to me and not a plan for anybody else.

20kg over 46 weeks, never went past 10mg, and constipation stayed mild the whole way. Posting because the loud threads are all 15mg.

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.

Screenshot none of this. Read the whole thread, including the parts where I am told I am wrong.

Trial identifiers corrected in the title. SURMOUNT and SURPASS are different programmes.

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.

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

u/blunt_coldbox2958 points·2 years ago

It is a dual GIP and GLP-1 receptor agonist, and the GIP arm is the part that has no equivalent in the semaglutide threads. That is why the side-effect profile reads differently rather than just milder.

The four-week interval in the label is a minimum. Nothing about the pharmacology requires you to step on schedule, and the trials stepped on a calendar because trials have to.

Not sure that follows. You went up a step and changed your training in the same fortnight.

SURMOUNT-1 ran 72 weeks with the top arm around 21% mean body weight change. SURPASS is the diabetes programme and reports glycaemic endpoints, so quoting the two interchangeably is a category error.

Pen or vial? The step sizes available differ and it changes this answer.

week 7 is early to draw any conclusion at all

Small fix: SURMOUNT is the obesity programme, SURPASS is the type-2 programme. They are different endpoints and the numbers do not transfer.

Saving this one. It is the clearest statement of the stall problem I have read here.

Vials and pens carry the same molecule; what differs is fill volume, device tolerance and whether you are doing your own arithmetic. Neither is inherently more accurate.

the reflux profile is genuinely gentler than people expect coming from sema

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.

sulphur burps are the signature complaint and they are not dangerous

Correction to my own post above — I said 12.5mg and I have been on 10mg since the spring. Same argument, wrong number.

Week 54 was the first time the scale moved after a five-week stall. I changed nothing in that window.

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

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

u/kofi_balogun1 point·2 years ago

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

u/emil_okwuosa96 points·2 years ago

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.

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.
