SURMOUNT-1 was -20.9% at 72 weeks. that is the number, not -30%

Discussion Receipts ×7 Long Haul ×2

SURMOUNT. That is the whole post, but I will justify it.

Everything else people worry about in c/glp1uk is downstream of it. Titration speed, reflux, the endless dose arguments — most of it resolves if you sort SURMOUNT out first, and almost nobody does.

I say this having got it wrong for 11 months. My fasting insulin was the thing that eventually made me pay attention, which is a stupid way to learn a lesson that was in the sidebar the whole time.

Week 21 on Mounjaro and 40kg 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

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

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

The confident tone is doing a lot of work that the evidence is not.

do not crack the pen, we have been over this

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

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

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

Water content matters more than people think. If a vial is carrying residual moisture, your "10mg" is not 10mg of peptide.

u/cato_girard20 points·15 days ago

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

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

Sceptical. If this were true we would see it reflected in the data and we do not.

dual agonism is SURPASS, do not generalise from semaglutide

Is that on Mounjaro pens or research tirzepatide?

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

u/hub_opssite staff36 points·16 days ago

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

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

week 30 on Mounjaro and the appetite profile is genuinely different from sema

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.
