is it normal to get constipation at week 7

Trial Data Receipts ×4

is it normal to get constipation at week 7, logged the same way every week so the comparison is at least internally fair.

Assumed the weight numbers were the point and was corrected. They are secondary to what this is being developed for.

Independent purity results for this compound are very sparse across the whole site, which means any impression about consistency is built on almost nothing.

Happy to answer the boring questions. Those are usually the ones worth asking.

Nothing containing this compound is approved anywhere. Research-use-only material is not approved for human use.

Which phase and which arm are you quoting?

u/diego_szabo65 points·1 months ago

Asked here what the difference was between the imaging and biopsy endpoints and got a genuinely excellent answer.

independent testing on this compound is very thin

Adding the standing caveat — unapproved compound, research material is not for human use.

Histological endpoints in this field are scored on biopsy: resolution of steatohepatitis without worsening of fibrosis, or improvement in fibrosis without worsening of steatohepatitis. Both are harder to achieve and to interpret than an imaging surrogate.

What does the tolerability table say at that dose?

Not convinced. Imaging-based fat fraction is not the same as a histological response and the paper is explicit about that.

u/cato_batistaOP19 points·1 months ago

Correction: that is the imaging endpoint, not the histological one. The paper reports both and they differ substantially.

u/thermal_mass_tom14 points·1 months ago

MASH endpoints are histological, which is a much harder bar

research material is not approved for human use, which is why the clinical record here is thin

Went slowly because everything published describes a deliberate escalation. That is the extent of what I will say about it.

u/sofia_danquah36 points·1 months ago

Imaging-derived liver fat fraction is a surrogate. It correlates with histology imperfectly, and a trial reporting one is not reporting the other.

replysharereportpermalink
u/britt_okwuosa17 points·1 months ago·edited

Yes — histological endpoints are a far harder bar than the surrogate measures people are used to quoting.

That figure is from the obesity programme, and this thread is about the hepatic one.

u/samir_falk1 point·1 months ago

Biopsy-confirmed population or imaging-selected?

replysharereportpermalink
u/endotoxin_elliemicro1 point·1 months ago·edited

Small fix — dual agonist, GLP-1 and glucagon. No GIP arm in this molecule.

replysharereportpermalink
u/liv_vukovic12 points·1 months ago

Agreed that the endpoint definitions matter enormously and almost nobody reads them before quoting a response rate.

replysharereportpermalink
u/annika_fonseca32 points·1 months ago

Careful with the mechanism claim. Glucagon agonism is plausible as an explanation and it has not been isolated as the operative one.

replysharereportpermalink
u/cato_batistaOP19 points·1 months ago

Correcting myself: the readout I quoted was the 46-week interim rather than the endpoint.

replysharereportpermalink
u/cormac_danquah5 points·29 days ago

Bought small because the evidence base is early. That is the only defensible position I could construct.

replysharereportpermalink
u/renzo_yildiz16 points·29 days ago

Looked for independent results across this whole site and found almost none. Worth knowing before forming an opinion.

replysharereportpermalink
u/protein_first_pnutrition8 points·29 days ago

This. Biopsy-confirmed and imaging-suggested are different evidentiary categories and get run together constantly.

replysharereportpermalink
u/honest_syringe_pls8 points·29 days ago

Cosigning on the glucagon arm. It is the mechanistic thread that connects the hepatic and the metabolic effects.

u/teodor_szabo20 points·29 days ago

Sent a vial to PeptideMeter because there was nothing on file. 99.3% against a claimed 99.0%. First entry for this compound in my own log.

c/survodutide rules
  1. Glucagon co-agonism has a distinct safety story. Do not generalise from tirzepatide.
  2. MASH claims need the trial and the biopsy endpoint.
  3. Not approved. Descriptive posts only.
  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.

Before you read on

Several compounds discussed on GLP Research Hub are sold for research use only and are not approved for human use anywhere. Nothing here is medical advice and none of it is written by your clinician. If a post reads like an instruction, treat it as a description of what one stranger did.
