is the tirz appetite thing actually different or am i imagining it

Titration Cold Box ×4

is the tirz appetite thing actually different or am i imagining it. If this has been answered properly somewhere, link me and I will delete.

Switching from semaglutide, since three people asked in this thread alone.

There is no published dose equivalence between the two. The conversion tables that circulate are somebody’s arithmetic, not data. What people report here is that the first month after a switch is often flat, that the appetite effect feels differently shaped rather than simply stronger, and that starting at the bottom of the ladder again is the common approach.

None of that is a recommendation. It is what the threads say, and the threads are not a clinic.

Week 61 was the first time the scale moved after a five-week stall. I changed nothing in that window.

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.

Corrections welcome, especially the pedantic ones. Pedantry is how this board earns its reputation.

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.

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

I would separate the two claims. That the GIP arm exists is uncontroversial; that it explains your food noise pattern is a guess.

switching from sema is not a dose conversion, there is no clean equivalence

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

Not sure about this bit. The GIP arm being real does not tell you that it is what caused your particular week.

Push back: "gentler than sema" is a population statement. Plenty of people on this board have the opposite experience and they are not doing it wrong.

Which week did the appetite change actually land for you?

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

This is the fifth "should I go up" post today and they are all welcome — but no member here can answer it for you.

dexa_twice_yearly is right that the two molecules are not interchangeable. There is no published conversion and the ones circulating are invented.

Right. And the sema-to-tirz "conversion" people post is invented. There is no published equivalence.

u/amara_halonen5 points·4 days ago

Disagree with the conversion table. There is no validated equivalence between the two molecules and posting one as though there is does real damage.

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.
