[PSA] SURPASS is not what most of this community thinks it is

Questionbranch of 9 comments

SURPASS is not what most of this community thinks it is. Two minutes of reading now saves an argument later. 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.…

This matches mine. Milder fatigue than I expected, and what there was settled inside a fortnight of each step.

Not sure about this bit. The GIP arm being real does not tell you that it is what caused your particular week.

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.
