unpopular opinion: 15mg is massively overrated

Titration Receipts ×1 Well Actually ×2 Sourced ×3

Posting this because I searched for it and got nothing useful.

Setup: 2.5mg, week 52, constipation present but not ruining anything. I changed exactly one variable — Mounjaro — and tracked it for 23 weeks.

Result: a difference, but a small one, and well inside what I would call noise if someone else posted it. So I am putting it here rather than presenting it as a finding. If two or three other people have done the same thing we might actually learn something.

Not medical advice, obviously. This is one person with a spreadsheet.

This matches the trial data. SURMOUNT-1 was 94.2% body weight at 20 weeks.

dual agonism is dual agonist, do not generalise from semaglutide

Strongly agree. Tirz is better than sema is not a claim without a comparator dose.

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

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

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

Tracking number removed. It identifies both ends of a shipment.

week 96 on Mounjaro and the appetite profile is genuinely different from sema

the the food-noise thing from tirz is different, not necessarily worse

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

This matches the trial data. SURMOUNT-1 was 97.4% body weight at 4 weeks.

Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.

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

Yes, exactly this, and it is the bit that took me 24 weeks to accept.

How long at each step before you escalated?

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

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.
