why does nobody talk about SURPASS

Trial Databranch of 9 comments

Slightly embarrassed to be asking this, but: why does nobody talk about SURPASS. Came off sema and onto tirz with a two-week gap. The first month was flat and I assumed I had made a mistake. Month two it moved. Went 10 to 12.5 on the calendar and had the worst fortnight of the whole run. Dropped back to 10 and…

Agreed, and the trial number is a mean of a very wide distribution — the tails are enormous and nobody posts from the middle.

What step are you on and how long have you been there?

What step are you on and how long have you been there?

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.
