[Lab] 4th independent test on JEEP — 97.3% on a claimed 97.0%, and the trend is the interesting part

Lab Receipts ×3 Sourced ×1

Result first, context after: 4th independent test on JEEP — 97.3% on a claimed 97.0%, and the trend is the interesting part. Everything below is how it was ordered, stored and sent.

Pulling the figures out of the title: 97.3% and 97.0%. All of it is written down as it happened rather than reconstructed.

Weekly dosing again, half-life in the same neighbourhood as sema, so a step change takes about a month to reach steady state. Judging a new step at day five is judging noise.

It is a dual GIP and GLP-1 receptor agonist, and the GIP arm is the part that has no equivalent in the semaglutide threads. That is why the side-effect profile reads differently rather than just milder.

Corrections welcome, especially the pedantic ones. Pedantry is how this board earns its reputation.

SURMOUNT-1 ran 72 weeks with the top arm around 21% mean body weight change. SURPASS is the diabetes programme and reports glycaemic endpoints, so quoting the two interchangeably is a category error.

Held 7.5 for five months. Everyone kept asking when I was going to 10. The answer was never, because 7.5 was working.

Left up, flair changed to Discussion. It is an opinion post and that is fine as long as it is labelled.

u/aurel_lindqvist47 points·4 months ago

Small fix: SURMOUNT is the obesity programme, SURPASS is the type-2 programme. They are different endpoints and the numbers do not transfer.

Week 34 was the first time the scale moved after a five-week stall. I changed nothing in that window.

sulphur burps are the signature complaint and they are not dangerous

SURMOUNT-1 landed around 21% at 72 weeks on the top arm

Saving this one. It is the clearest statement of the stall problem I have read here.

Disagree with the conversion table. There is no validated equivalence between the two molecules and posting one as though there is does real damage.

pens and vials are the same molecule, the price is the difference

Push back: "gentler than sema" is a population statement. Plenty of people on this board have the opposite experience and they are not doing it wrong.

u/taper_off_tabitha47 points·4 months ago

Did you come to this from sema, and if so how long was the gap?

replysharereportpermalink
u/elin_vargaOP18 points·4 months ago

Pen or vial? The step sizes available differ and it changes this answer.

u/marta_dziedzic4 points·4 months ago·edited

Right. And the sema-to-tirz "conversion" people post is invented. There is no published equivalence.

replysharereportpermalink
u/rania_diallo1 point·4 months ago

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

u/swirl_dont_shakereconstitution3 points·4 months ago

Cosigning the four-week thing. It is a minimum interval, and treating it as a schedule to keep up with is how people end up miserable at 12.5.

Correction to my own post above — I said 7.5mg and I have been on 5mg since the spring. Same argument, wrong number.

elin_varga is right that the two molecules are not interchangeable. There is no published conversion and the ones circulating are invented.

the reflux profile is genuinely gentler than people expect coming from sema

u/hub_opssite staff29 points·4 months ago·edited

Appetite effect for me is flat across seven days. On sema it was a wave. Same person, different molecule.

week 10 is early to draw any conclusion at all

u/coring_the_stopper13 points·4 months ago·edited

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

the four-week step schedule is the label, not folklore

u/elin_ferrari2 points·4 months ago

Same experience with the appetite effect being flatter across the week rather than front-loaded.

Yes — 10mg being a genuine landing place for a lot of people is underrated. There is no medal for 15.

u/kaia_cabrera6 points·4 months ago

if 7.5 is working, 10 is not automatically better

u/line_petrov4 points·4 months ago

Agree. The GIP component is the interesting half and it barely gets discussed outside c/glp1science.

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.
