[Discussion] the 15mg advice in here is 3 years out of date

Discussion Well Actually ×3 Long Haul ×1 Receipts ×1

I have had 17 orders now and I keep a table, so here is the honest summary rather than a vibe.

Material has been consistent. Communication has not. Shipping has varied by about 14 days on nominally the same lane, which matters more in summer than in February.

The independent number came back 93.7% against a claimed 94.2%, which I read as agreement rather than a discrepancy — inter-lab variance on this assay is a point or two either way and treating one lab as ground truth is how people end up in pointless arguments with vendors.

Batch number is in the comments. Ask if you want the method.

the early fullness from tirz is different, not necessarily worse

week 21 on Mounjaro and the appetite profile is genuinely different from sema

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

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

Tracking number removed. It identifies both ends of a shipment.

My fasting insulin moved faster on tirz than on sema at the same timepoint, which matches what people report.

u/slow_logbook_ftwOP1 point·3 months ago

Switched from sema at 5mg to tirz at 7.5mg. Different drugs, cannot compare the doses directly.

Switched from sema at 2.5mg to tirz at 2.4mg. Different drugs, cannot compare the doses directly.

week 68 on Mounjaro and the appetite profile is genuinely different from sema

Slight fix: the number was 98.6, not 98.7. Decimal point, but a fairly consequential one.

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

Titration speed is a side-effect dial far more than an efficacy dial.

replysharereportpermalink
u/ingrid_correia303 points·3 months ago

The dual agonism story is real. The appetite is physically different from semaglutide alone.

u/adnan_nascimento49 points·3 months ago

the GIP side does different things than the GLP-1 side, that is the point

u/crosspost_bot_no13 points·3 months ago

Not to be pedantic but tirzepatide and Mounjaro are being used interchangeably and they are not interchangeable in real life.

replysharereportpermalink
u/laila_wikstrom5 points·3 months ago

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

replysharereportpermalink
u/line_petrov49 points·3 months ago

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

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.
