reading tirzepatide threads from 2024 and half of it aged badly

Discussion Clean Column ×8 Long Haul ×1 Well Actually ×3

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

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

I say this having got it wrong for 20 months. My triglycerides 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.

Respectfully this is a sample of one presented as a finding.

Week 49 on Mounjaro and 25kg down. The appetite reduction feels different from sema in ways I do not have words for yet.

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

u/incretin_ivypharmacology176 points·1 year ago

Small correction: the trial was 10 weeks, not 20. Does not change your point but people will quote it.

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

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

That is net peptide content, not purity. Different number, different meaning.

do not crack the pen, we have been over this

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

u/zeynep_zielinski113 points·1 year ago

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

Dead space in the needle hub holds a small but non-trivial volume. On low-volume draws that can be several units.

Crossposting this to c/compounding because the people who need it are not reading this community.

u/zaid_balogun71 points·1 year ago·edited

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

u/piotr_nascimento39 points·1 year ago

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

u/certified_referenceOPQC22 points·1 year ago

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

u/fatima_wojcik22 points·1 year ago

Titration speed is a side-effect dial far more than an efficacy dial.

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

Disagree on that part. 93.7% and 99.3% on the same vial is normal.

Not to be pedantic but tirzepatide and GIP are being used interchangeably and they are not interchangeable in real life.

u/hugo_bergstrom1 point·1 year ago

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

replysharereportpermalink
u/certified_referenceOPQC1 point·1 year ago

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

u/dexa_twice_yearlybody comp2 points·1 year ago

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

replysharereportpermalink
u/ewan_marchand22 points·1 year ago

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

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.
