[Discussion] can we stop arguing about Zepbound until somebody posts a number

Discussion Cold Box ×7 Well Actually ×2 Receipts ×2

Genuinely asking, not being difficult.

Everyone in c/semaglutide repeats that dual agonist is important. I believe it, but I have never seen anyone show why, and when I search I get 6 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.

do not crack the pen, we have been over this

No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.

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

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

week 73 on Mounjaro and the appetite profile is genuinely different from sema

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

How long at each step before you escalated?

u/priya_guerrero245 points·1 year ago

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

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

u/incretin_ivyOPpharmacology1 point·1 year ago

Cosigning.

Yes, exactly this, and it is the bit that took me 31 weeks to accept.

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

replysharereportpermalink
u/dario_vermeulen1 point·1 year ago

Cosigning.

Adding to this: 15mg is doing more work than the comment implies.

the reflux from tirz is different, not necessarily worse

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

Retitled to remove editorialising. Put the evidence in the body.

u/nordic_pricing57 points·1 year ago

Slight fix: the number was 97.6, not 97.9. Decimal point, but a fairly consequential one.

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

u/graph_it_gary102 points·1 year ago

Half-life is about 168 hours, so steady state lands around week 7–5. Practical consequence: what you feel in week 1 is not what that dose does.

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

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.
