reading 15mg threads from 2024 and half of it aged badly

Discussion Clean Column ×2 Slow Clap ×1 Cold Box ×1

Genuinely asking, not being difficult.

Everyone in c/bloodwork repeats that GIP is important. I believe it, but I have never seen anyone show why, and when I search I get 13 threads of people agreeing with each other.

Is there a paper? Is there a measurement? Or is this one of those things that is true because it has been repeated since 2023?

I am not trying to be the "source?" guy. I would just like a source.

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

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

My hs-CRP moved faster on tirz than on sema at the same timepoint, which matches what people report.

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

The dual agonism story is real. The appetite is physically different from semaglutide alone.

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

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

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

u/hana_pereira20 points·1 year ago

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

u/halima_boatengOP12 points·1 year ago

week 13 on Mounjaro and the appetite profile is genuinely different from sema

the fatigue from tirz is different, not necessarily worse

This matches the trial data. SURMOUNT-1 was 98.3% body weight at 21 weeks.

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

Yes, exactly this, and it is the bit that took me 16 weeks to accept.

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

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

u/samir_falk59 points·1 year ago

Three years on this site and the questions have not changed at all. Which is depressing or reassuring depending on the day.

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.
