This page shows what was measured, who it was measured in, and what that does not settle.

What Tirzepatide does in the body

Tirzepatide is a single peptide shaped to fit both receptors, with a long fatty tail that keeps it circulating for about five days.

Your gut releases two different "you have eaten" hormones after a meal, GIP and GLP-1. Older drugs in this family imitated one of them. The result is stronger appetite suppression than imitating GLP-1 alone, and, in the one trial that compared them directly, more weight lost.

Why people take it. Type 2 diabetes, obesity, and obesity-related sleep apnoea

What happened in people

20.9% mean weight loss at 72 weeks on 15 mg versus 3.1% on placebo (SURMOUNT-1, n=2,539)

Words this page uses

Four words worth knowing first

Chosen from what this page shows, with each one explained before the word it depends on.

Biomarker

A biomarker is a number from a test that stands in for something about health.

A picture of it, and where the picture fails

A biomarker is like a fuel gauge.

Where that stops being true. A gauge is wired to the tank. Many biomarkers are only loosely tied to health.

What people get wrong. A better number is read as a better life. Several medicines improved a number and helped nobody.

A measurable indicator used as a substitute for a clinical outcome of interest.

Stand-in result

A stand-in result is a number measured because the real result takes too long.

A picture of it, and where the picture fails

It is like judging a journey by the speedometer rather than by arriving.

Where that stops being true. Speed does predict arrival. Many stand-in results do not predict the real one.

What people get wrong. A stand-in result is often reported as the result itself.

A surrogate endpoint substituted for a clinical endpoint, valid only where the substitution has been shown to hold.

What happened in peopleRead from sources, not yet reviewed

What was measured, goal by goal

One row for each goal a registered study measured something for. One column for each kind of thing that could be measured.

Registered studies list 40 outcome measures that RNAWiki could read. A registered study says what someone planned to measure. It does not say what they found. 0 of the matched studies tested this substance, and 0 posted a result.

There is no single score. A strong test result and a weak life result are different facts.

Goals down the side, kinds of measurement across the top. Each cell says what kind of thing was registered, not what was found.

What happened in peopleRead from sources, not yet reviewed

How close this is to real life

The top step is something a person would feel or care about. The bottom is a guess from software. Filled steps are where evidence exists for this substance.

  1. Living longer, or avoiding a major event Evidence recorded. Death, a heart attack, a stroke, a hospital stay.1 registered measure of this kind. No reviewed result.
  2. What a body can do day to day Evidence recorded. Walking, dressing, breathing, recovering.1 registered measure of this kind.
  3. Measured performance Evidence recorded. How much was lifted, how far was run, how fast.1 registered measure of this kind.
  4. Symptoms and quality of life Evidence recorded. Pain, tiredness, mood, sleep, as the person rated it.1 registered measure of this kind.
  5. A number that stands in for health Evidence recorded. Cholesterol, blood sugar, bone density. A stand-in, not the thing itself.18 registered measures of this kind.
  6. A step measured inside a person Evidence recorded. Something measured in human tissue or human cells.A human record sits on the stored organism ladder.
  7. Animals No evidence recorded. Mice, rats, dogs. Useful for ideas, not proof about people.No animal record is stored.
  8. Cells in a dish Evidence recorded. Cells or chemistry on a bench, far from a whole body.Stored mechanism abstracts describe steps measured in cells or tissue.
  9. A guess from software No evidence recorded. Nobody measured it. RNAWiki never publishes one as a finding.RNAWiki stores no prediction for this record. Software can suggest a link. RNAWiki does not publish one as a finding.

Higher on these steps means closer to something a person would feel. It does not mean better done.

What it changes in the bodyRead from sources, not yet reviewed

The path through the body

From what a person takes to what changes. A solid line is a step measured in people. A dashed line is a step nobody has measured that way.

Where a source records it acting

  • Stomach: Delays gastric emptying; slows post-meal glucose absorption

    US prescribing information · 0818426a-53eb-4db7-9609-bbae1e7a3964 · read 2026-08-27

  1. Start

    Tirzepatide

    What a person takes: Subcutaneous once-weekly single-dose pen, single-dose vial, or multi-dose KwikPen.

    The measurement behind this step

    Clear solution supplied at six strengths from 2.5 mg to 15 mg, injected once weekly with a 20-week stepwise escalation to the maintenance dose.

  2. Getting in

    Weekly injection with a twenty-carbon anchor

    The molecule carries a longer fatty tail than semaglutide, which grips albumin more tightly and keeps a steady level across the week.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    The C20 eicosanedioic diacid arm on Lys20, plus Aib at positions 2 and 13 blocking DPP-4 cleavage, give a half-life of about five days.

  3. Reaching the cell

    Two receptors, one molecule

    It docks into two different hormone receptors. Everything before it in this class docked into one.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    The backbone is derived from GIP and engineered to retain GIP receptor agonism while acquiring GLP-1 receptor agonism, with unbalanced potency favouring GIPR.

  4. What it acts on

    Beta cell and alpha cell signalling

    In the pancreas it increases insulin release when glucose is high and reduces the hormone that raises glucose.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    Both receptors are Gs-coupled and raise cAMP. GIPR agonism adds an effect on alpha cells and on adipose tissue that GLP-1R agonism alone does not have.

  5. The change it makes

    Appetite suppression plus an adipose-tissue effect

    Appetite falls as with any drug in this class, and there appears to be an additional effect on how fat tissue handles energy.

    Measured in people. Written by a person from the study named beside the step. Not signed off as a reviewed claim.

    The measurement behind this step

    Central GLP-1R and GIPR signalling suppress food intake; GIPR signalling in adipocytes is proposed to improve lipid buffering and insulin sensitivity, though the human evidence for that mechanism is indirect.

  6. What that does for a person

    The largest average weight loss of any approved drug, so far

    At the top dose, about a fifth of body weight over 72 weeks, plus lower HbA1c and fewer apnoea events during sleep.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    Mean -20.9% at 72 weeks in SURMOUNT-1, HbA1c reduction of up to 2.30 percentage points in SURPASS-2, and a reduced apnoea-hypopnoea index in SURMOUNT-OSA.

No suggested links are held for this record, so nothing is hidden from this path.

What we know
The record describes 5 steps from taking it to an effect in a person.
How we know it
Each step names the study behind it in the technical detail beside it.
What this does not prove
A change inside the body is a reason to look. It is not a result in a person.
Why it matters
A reader can see exactly where the chain stops being measured in people.
What we still do not know
No reviewed claim binds any of these steps to a named population.

What it would be like to takeRead from sources, not yet reviewed

Felt, measured, or meaningful

Three different things that get called the same word. Registered studies measured all three, and mixing them is how a blood test becomes a health claim.

Felt

Things a person could notice without a test.

  • kansas city cardiomyopathy questionnaire clinical summary

Measured

Things only a test, a scale or a device shows.

  • haemoglobin a1c
  • hemoglobin a1c
  • body weight
  • who achieve 5 body weight reduction
  • hba1c
  • weight loss
  • levels of lipids in circulation
  • kilograms of lean mass by dual energy x ray absorptiometry
  • body mass index
  • glycated haemoglobin

and 9 more.

Meaningful

Things that change how a life goes, not only a number.

  • from randomization to first occurrence of death from mace 3

A registered study says what someone planned to measure. It does not say what they found. A number moving is not the same as a life going better. The two are shown apart here.

Felt, but not shown to help. A person notices a change. No study showed it leads anywhere good.

Measured, but not felt. A number moves. The person notices nothing. Both can be true.

Measured, but not shown to matter. A number moves in the good direction. Nobody showed that lives went better.

Matters, but takes years. The result that counts may take longer than anyone would keep watching.

Names that fit none of the three (19)
  • one or more serious adverse event
  • total clamp disposition index
  • apnea hypopnea index
  • brain function
  • mdsc in peripheral blood
  • assessment of complete pathologic response
  • allocated to each isa
  • gastrointestinal symptoms
  • hidradenitis suppurativa clinical response 50
  • main objective of registry
  • presence of rgv in stomach
  • tracking the use of intubation due to rgv
  • aspiration events due to rgv
  • treatment emergent adverse events
  • incidence and severity of adverse events
  • primary objective
  • safety and adverse events
  • composite cv outcome
  • binge eating episodes

These are harms, study-process measures, or names the rules did not recognise. They are shown rather than dropped.

What it would be like to takeRead from sources, not yet reviewed

How long anything takes

Nine different lengths of time that get confused with each other. None of them is worked out from another.

  1. Before anything is noticed. RNAWiki does not store this separately, and never works it out from another figure on this page.

  2. Before a test result moves. RNAWiki does not store this separately, and never works it out from another figure on this page.

  3. Before performance moves. RNAWiki does not store this separately, and never works it out from another figure on this page.

  4. How long the result was watched. No finished study window is recorded for a study that tested this substance.

  5. How long people took it. How long people actually took it is not stored. The study window is not the same thing.

  6. How long people were followed. Follow-up length is not stored separately. It is never read off the study window, which would be a different thing.

  7. How fast the body clears it. approximately 5 days

    Read from the label, which states: “The apparent population mean clearance of tirzepatide is 0.061 L/h with an elimination half-life of approximately 5 days, enabling once-weekly dosing.”

  8. How long effects linger. RNAWiki does not store this separately, and never works it out from another figure on this page.

  9. Beyond the studies. Nothing is recorded about the long term.

    The longest finished study sets the edge of what anyone measured.

A study window is not how long people took it, and neither is how long they were followed. Where RNAWiki holds only one of the three, it shows one.

Where the result stopped carrying

  • Earlier unbalanced GIP/GLP-1 co-agonists in the same programme did not reach the potency needed for a weekly human dose
  • The superiority hypothesis in SURPASS-CVOT, which was prespecified and not met
  • This is a scope explorer, not a diagnosis engine.
  • It shows who was studied so you can see whether people similar to you were included.

RNAWiki cannot tell whether a study fits you. It can show who was in it.

What it would be like to takeRead from sources, not yet reviewed

Why it might seem to do nothing

A real effect and a noticed effect are different things. These are the recorded reasons the two come apart.

It was studied for a different goal

The studies measured something else entirely.

On this record: Some registered studies measured things that match no goal on this page.

It was studied in different people

The people in the studies were not much like the reader.

On this record: Which groups were under-represented in the studies has not been recorded for this substance. Pregnancy, breastfeeding, children, older adults, and people with liver or kidney conditions are commonly excluded from trials; nothing here says whether they were.

The evidence may simply be wrong

Small early studies often do not hold up.

On this record: RNAWiki has not yet published a reviewed conclusion for this use.

Other reasons RNAWiki checked and found nothing for (10)
A different form was studied
The studied form is not the form on the shelf. Nothing in this record points to this reason.
There was nothing to correct
Where a level is already normal, topping it up may change nothing. Nothing in this record points to this reason.
Something else had to happen too
In the studies it was paired with training, a diet or another treatment. Nothing in this record points to this reason.
The change is too small to feel
A real change can still sit below what a person notices. Nothing in this record points to this reason.
Day-to-day swing hides it
Sleep, food, stress and time of day move most numbers more than this would. Nothing in this record points to this reason.
Not enough time yet
The studies ran longer than the person has waited. Nothing in this record points to this reason.
It was not taken as studied
Missed days change the result, and studies count them. Nothing in this record points to this reason.
Something else changed at the same time
Two changes at once cannot be told apart afterwards. Nothing in this record points to this reason.
The product may not be what it says
Contents of a sold product are not always what the label states. Nothing in this record points to this reason.
No recorded reason
RNAWiki has nothing stored that would explain it. Nothing in this record points to this reason.

None of these is a reason to take more. Taking more is not a step this page ever suggests.

What can go wrong

Sorted by where each line came from. A regulator's label and a report somebody sent in are not the same kind of fact.

Worth asking a clinician aboutWritten into the record from the studies named on this page

Nausea, diarrhoea, vomiting and constipation are the dominant adverse events and cluster during escalation. Acute pancreatitis, gallbladder disease and acute kidney injury from volume depletion are uncommon. Boxed warning for thyroid C-cell tumours based on rodent data; contraindicated with a personal or family history of medullary thyroid carcinoma or MEN2.

Nobody counted how many people took this and were fine, so this cannot be turned into a rate.

Where this came from

Reports sent to a regulator

  • These are reports people sent to a regulator. They do not show the medicine caused the reaction.
  • Nobody counted how many people took the medicine and reported nothing.
  • The same event can be reported more than once, and many reports are incomplete.
  • News coverage, lawsuits and new warnings change how often people report.
  • A count is not a rate and not a risk.

Tirzepatide appears in spontaneous reports to regulators. Across the 2 most-reported reaction terms, 10 reaction mentions were counted. One report can name several reactions.

The recorded terms (2)
  • weight decreased — 6 reaction mentions
  • diabetic ketoacidosis — 4 reaction mentions

Over a long time. No completed tested study window is recorded, so long-term effects are not established by the registry record.

Groups the studies covered thinly. Which groups were under-represented in the studies has not been recorded for this substance. Pregnancy, breastfeeding, children, older adults, and people with liver or kidney conditions are commonly excluded from trials; nothing here says whether they were.

What it would be like to takeRead from sources, not yet reviewed

What you could measure

This one is decided with a clinician, so this section holds questions to ask rather than a plan to run.

RNAWiki could not confidently classify this substance, so no self-experiment plan is offered.

Questions worth asking

  • Which of the trials of Tirzepatide studied people like me?
  • What was measured, and for how long?
  • Was the result a laboratory value or a health outcome?
  • What would we watch for, and when would we stop?

Tracking can show whether something changed for you. It cannot show what caused it.

RNAWiki records evidence. It does not say whether this substance is right for you.

Claims that go past the evidence

Things said about this substance that sound reasonable, and the exact step that is missing between the evidence and the claim.

Goes past the evidence

That the weight-loss advantage over semaglutide implies a cardiovascular advantage; the outcome trial did not show one

Why it sounds right. It follows from something real on this page: a body step, an animal result or a related finding.

The missing step. Nobody measured this in people for this use, or the study that did measure it did not show it.

What would change this

A study in people, for this exact use, measuring this exact thing, that a reviewer signs off.

RNAWiki has not yet published a reviewed conclusion for this use.

Goes past the evidence

That the GIP receptor component is the reason for the extra weight loss, which no human trial has isolated

Why it sounds right. It follows from something real on this page: a body step, an animal result or a related finding.

The missing step. Nobody measured this in people for this use, or the study that did measure it did not show it.

From the source
The 2024 JAMA Network Open cost-based-price analysis covers insulins, SGLT2 inhibitors and four GLP-1 agonists, but not tirzepatide. The 2023 Obesity estimated-minimum-price paper searched tirzepatide prices but reported estimated minimum prices only for semaglutide, liraglutide, orlistat, phentermine/topiramate and naltrexone/bupropion. This dossier therefore carries no pricing block.

The older medicine-wide conclusion held in this record

Written for a clinical reader, and about the medicine as a whole rather than about one indication, population and set of trials. RNAWiki does not treat it as a programme conclusion and no reviewer has signed it off in that form. It is here word for word because it is what the record holds.

A single 39-residue peptide that switches on both incretin receptors at once, producing 20.9% mean weight loss at 72 weeks in SURMOUNT-1 and beating semaglutide head-to-head, without yet beating an older GLP-1 on cardiovascular events.

What do 10 spontaneous reports say about Tirzepatide — and not say?


These are reports people sent to a regulator. They do not show the medicine caused the reaction. Nobody counted how many people took the medicine and reported nothing. The same event can be reported more than once, and many reports are incomplete. News coverage, lawsuits and new warnings change how often people report. A count is not a rate and not a risk.

Tirzepatide appears in spontaneous reports to regulators. Across the 2 most-reported reaction terms, 10 reaction mentions were counted: weight decreased 6; diabetic ketoacidosis 4. open-targets-adr · CHEMBL4297839 · 2026-06-24

    "Inhibition of autophagy or NAMPT abolished the mitochondrial and reno-protective effects of tirzepatide."
  • PMID 42114682
    "Taken together, our findings demonstrate that tirzepatide protects against cisplatin‑induced AKI by enhancing NAMPT‑dependent NAD + restoration and promoting mitophagy, highlighting a promising therapeutic strategy for chemotherapy‑related nephrotoxicity."

AMPK

  • PMID 42119472
    "Mechanistically, Tirzepatide activated the AMPK signaling pathway and suppressed NF-κB p65 phosphorylation-effects that were reversed by the AMPK inhibitor Compound C. Tirzepatide also reduced the mRNA expression of downstream NF-κB target genes TNF-α, IL-6, and iNOS, an effect abrogated by Compound C."
