[Question] Mounjaro — what am I missing here

Question Clean Column ×8 Slow Clap ×1

Confession thread, sort of.

I went from 5mg to 1.7mg much faster than I should have because the scale had stalled and I got impatient. The stall broke about 15 weeks later, at which point I had no way of knowing whether the dose increase did anything or whether it would have broken anyway.

So now I have reflux I did not need and a data point I cannot interpret. Two lessons in one.

Posting it in the hope that somebody at week 94 reads it before doing the same thing.

Cosigning. The GIP contribution is real and the side effects are not simply scaled versions.

Tried both. Sema worked, tirz worked better for me, but my reflux profile was worse on tirz.

Tried both.

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.

the dual agonism hits different and that is why people describe it differently

u/nabila_ogunleye-16 points·1 year ago

Disagree. What you are describing is consistent with 15mg, not with what you concluded.

Yeah, dual agonism does produce a different appetite profile than GLP-1 alone.

Removed a chain here. The rule is one line long and it is not negotiable.

Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.

Is that on Mounjaro pens or research tirzepatide?

the appetite change on tirz is more than just reduced hunger, it is different machinery

the GIP side does different things than the GLP-1 side, that is the point

The SURMOUNT readouts are real but less consistent than STEP. Some people plateau earlier on tirz.

Vial-splitting is on-topic here. Do not ask about pen-cracking, that goes in c/reconstitution.

Slight fix: the number was 95.1, not 94.2. Decimal point, but a fairly consequential one.

dual agonism is SURPASS, do not generalise from semaglutide

u/laila_yilmaz2 points·1 year ago

Zepbound and Mounjaro are literally the same drug, the name is the only difference

u/aksel_kjaer1 point·1 year ago

Did you stay on semaglutide or switch? The outcome is different if you are comparing.

u/nordic_pricing22 points·1 year ago

stalled on sema, tried tirz, and the curves were actually different shapes

replysharereportpermalink
u/customs_seizure_sid17 points·1 year ago

Respectfully this is a sample of one presented as a finding.

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.
