[Discussion] "tirz is stronger than sema" needs a comparator dose or it means nothing

Discussion Receipts ×4 Slow Clap ×2

Been lurking in c/compounding for about 21 months and finally have something worth posting.

Short version: week 53, 5mg, and GIP is the bit I still cannot get a straight answer on. I have read the wiki, I have read the last 37 threads, and the answers split roughly down the middle.

What I actually want to know is whether the people saying it does not matter have measured it, or whether it is just repeated confidently. Happy to be told I am overthinking this — I probably am — but I would rather overthink it now than at week 47.

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

week 59 on Mounjaro and the appetite profile is genuinely different from sema

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

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

Week 25 on Mounjaro and 23kg down. The appetite reduction feels different from sema in ways I do not have words for yet.

Switched from sema at 1.0mg to tirz at 1.0mg. Different drugs, cannot compare the doses directly.

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

Is that on Mounjaro pens or research tirzepatide?

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

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

genuinely useful, thanks

This matches the trial data. SURMOUNT-1 was 99.0% body weight at 11 weeks.

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

Slight fix: the number was 99.0, not 98.9. Decimal point, but a fairly consequential one.

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.
