[Lab] split one vial across Medutest and Janoshik — 98.3% and 98.7%

Lab Cold Box ×1 Clean Column ×2 Receipts ×2

Numbers in the title, numbers in the post. split one vial across Medutest and Janoshik — 98.3% and 98.7%.

Since the title puts numbers in the shop window: 98.3% and 98.7%.

Sulphur burps for the first eight days after each step, then nothing. Predictable enough that I planned my week around it.

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.

Would rather be corrected in public than confident in private.

Research-use-only material is not approved for human use. Anything in this thread about how a research vial "should" titrate is a discussion about chemistry, not a plan.

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

u/elin_varga472 points·2 years ago

What is the waist doing? That is usually the number still moving during a scale stall.

The thing nobody warned me about was how much of this is logistics — storing it, remembering it, the same day every week.

u/mikkel_kimani263 points·2 years ago

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.

The four-week interval in the label is a minimum. Nothing about the pharmacology requires you to step on schedule, and the trials stepped on a calendar because trials have to.

Which week did the appetite change actually land for you?

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

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

u/laila_wikstrom23 points·2 years ago

if 7.5 is working, 10 is not automatically better

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

u/mikkel_ogunleyeOP34 points·2 years ago

2.5mg is a four-week starting dose, not a maintenance dose. Worth being precise since people search these threads.

u/priya_guerrero227 points·2 years ago

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

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

hold the dose that works, the ladder is not a leaderboard

u/kaia_wojcik394 points·2 years ago·edited

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.

replysharereportpermalink
u/mikkel_ogunleyeOP201 points·2 years ago·edited

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

replysharereportpermalink
u/sten_palacios218 points·2 years ago

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

replysharereportpermalink
u/kaia_cabrera108 points·2 years ago

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

u/ignacio_vanhecke83 points·2 years ago

Have you held a step for longer than the four-week minimum at any point?

replysharereportpermalink
u/discount_math_dm158 points·2 years ago

Yes. I stepped to 12.5 because the calendar said so, not because anything needed fixing, and I regretted it for a fortnight.

u/nz_unfunded124 points·2 years ago

the appetite effect is blunter than sema, in a good way, most weeks

replysharereportpermalink
u/emil_okwuosa79 points·2 years ago

Vials and pens carry the same molecule; what differs is fill volume, device tolerance and whether you are doing your own arithmetic. Neither is inherently more accurate.

the trials titrated on a calendar, real people titrate on symptoms

u/teodor_szabo112 points·2 years ago

13kg over 61 weeks, never went past 10mg, and muscle cramps stayed mild the whole way. Posting because the loud threads are all 15mg.

replysharereportpermalink
u/ignacio_vanhecke62 points·2 years ago

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.

stepping every four weeks is a ceiling on speed, not a schedule you must hit

replysharereportpermalink
u/slow_logbook_ftw52 points·2 years ago

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

u/two_mil_or_one42 points·2 years ago

switching from sema is not a dose conversion, there is no clean equivalence

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.
