c/tirzepatide·posted 26 days ago by u/dario_vermeulen

my resting HR went from 58 to 66 on titration and settled back

Question Receipts ×8

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 12 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.

Mechanistically the bit that matters is GIP. It explains most of the early profile and a decent chunk of the outcome.

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

This matches the trial data. SURMOUNT-1 was 97.6% body weight at 16 weeks.

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

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

dual agonism is SURPASS, do not generalise from semaglutide

u/kofi_balogun3 points·24 days ago

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

Is that on Mounjaro pens or research tirzepatide?

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

What was the trial arm you are quoting from? SURMOUNT-1, -2, -3 are all different.

Disagree on that part. 99.0% and 98.9% on the same vial is normal.

This matches the trial data. SURMOUNT-1 was 93.7% body weight at 20 weeks.

Week 73 on Mounjaro and 42kg down. The appetite reduction feels different from sema in ways I do not have words for yet.

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.
