[Discussion] we are measuring Zepbound at the wrong time and calling it noise

Discussion Well Actually ×2 Cold Box ×3 Clean Column ×3

Posting this because I searched for it and got nothing useful.

Setup: 2.5mg, week 84, sulphur burps present but not ruining anything. I changed exactly one variable — Mounjaro — and tracked it for 9 weeks.

Result: a difference, but a small one, and well inside what I would call noise if someone else posted it. So I am putting it here rather than presenting it as a finding. If two or three other people have done the same thing we might actually learn something.

Not medical advice, obviously. This is one person with a spreadsheet.

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

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

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

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

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

This matches the trial data. SURMOUNT-1 was 99.3% body weight at 9 weeks.

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

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

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

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

You have restated the marketing copy. What is the actual substance here.

the fatigue from tirz is different, not necessarily worse

u/two_mil_or_one36 points·2 years ago

Did the constipation feel the same as on tirz or genuinely different?

u/throwaway_titration-26 points·2 years ago

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

u/kofi_balogun1 point·2 years ago

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

u/elin_ferrari33 points·2 years ago

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

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

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

u/cormac_pereira18 points·2 years ago

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

Is that on Mounjaro pens or research tirzepatide?

This matches the trial data. SURMOUNT-1 was 97.9% body weight at 22 weeks.

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.
