switched from 7.5mg to 15mg and the nausea got better, not worse

Titration Receipts ×5

Trying to settle this properly because the thread from last year went in circles.

The claim: SURMOUNT matters. The counter-claim: it is measurement error. Both sides have been asserting it confidently for about 2 months without either producing anything.

What would actually settle it is 11 people measuring the same thing the same way. I have started; my numbers are below. They lean one way but not strongly enough for me to declare victory.

If you have data, post the data. If you have an opinion, flair it as an opinion.

Adding to this: Mounjaro is doing more work than the comment implies.

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

This matches the trial data. SURMOUNT-1 was 98.0% body weight at 5 weeks.

This is an urgent-care question wearing a forum question's clothes. Please contact a clinician rather than waiting for replies.

week 17 on Mounjaro and the appetite profile is genuinely different from sema

u/ahmed_iyer20 points·7 months ago

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

Week 57 on Mounjaro and 45kg down. The appetite reduction feels different from sema in ways I do not have words for yet.

the 15mg is the top of the pen, not the required dose

the fatigue from tirz is different, not necessarily worse

This matches the trial data. SURMOUNT-1 was 93.7% body weight at 9 weeks.

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

This is the "correlation is mechanism" thing again. You changed three variables at once.

SURMOUNT data is messier than STEP data but the weight loss is there

u/quiet_moderatormod39 points·7 months ago

How long at each step before you escalated?

u/certified_referenceQC18 points·7 months ago

nope, the equivalence to semaglutide is not known, comparing 15mg tirz to 2.4mg sema is guessing

Hard agree. The food noise disappears differently on the two compounds.

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.

Several compounds discussed on GLP Research Hub are sold for research use only and are not approved for human use anywhere. Nothing here is medical advice and none of it is written by your clinician. If a post reads like an instruction, treat it as a description of what one stranger did.
