is it normal to get muscle cramps at week 86

Trial Data Sourced ×6 Slow Clap ×2

Update, and the title has the headline: is it normal to get muscle cramps at week 86.

Compared milligram figures across two completely different molecule classes in a comment. Deserved the correction.

Went looking for independent testing on this and found essentially nothing, which was clarifying.

Not medical advice, obviously, and nothing here is approved for human use. One person with a spreadsheet.

Analytically this is a small-molecule identity and purity problem, not a peptide one. The methods, the impurity classes and the reference standards are all different.

What did the tolerability table look like at that dose?

u/paloma_stanescu-24 points·9 months ago·edited

Disagree. You are comparing doses across a small molecule and a peptide, which is not a comparison of anything.

u/anders_karlsen1 point·9 months ago·edited

I would not assume the tolerability profile transfers exactly. Similar class effects, different exposure profile.

Milligram comparisons across molecule classes are meaningless. Potency is a property of the molecule at its receptor, not of the number on the label.

Milligram comparisons across molecule classes are meaningless.

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

The no-timing-restriction thing is the part I would care about most in practice, and it barely gets mentioned here.

the manufacturing story is genuinely different from the injectables

lina_novak is right that milligram comparisons across classes tell you nothing.

Not convinced. Oral semaglutide is a peptide formulated with an absorption enhancer; the comparison you are making does not hold.

nothing containing this is approved anywhere and research material is not for human use

Spent an evening reading about small-molecule agonism at a peptide receptor. Genuinely interesting engineering.

That is a phase 2 result being quoted as though the programme had reported.

Daily dosing, so what does the exposure profile look like across the day?

replysharereportpermalink
u/purity_pedantanalytical11 points·9 months ago

Careful — purity methods for peptides do not read across to a small molecule and the numbers are not equivalent.

replysharereportpermalink
u/lina_novakOP8 points·9 months ago

daily dosing, not weekly, so the exposure profile is different

replysharereportpermalink
u/chidi_yilmaz25 points·9 months ago

Daily rather than weekly sounds trivial until you think about what a missed dose means in each case.

replysharereportpermalink
u/niels_norgaard14 points·9 months ago

Push back: daily dosing is not automatically better adherence. It is a different failure mode, not a solved problem.

u/first_hundred10 points·9 months ago

a non-peptide agonist does not degrade the way a peptide does

replysharereportpermalink
u/declared_value_dv7 points·9 months ago

Is that from the publication or the press release?

Cosigning on daily dosing. It changes the exposure profile and it changes adherence, in both directions.

replysharereportpermalink
u/fabio_lehtinen3 points·9 months ago

Daily dosing gives a very different exposure profile from a weekly injectable: peaks and troughs within each day rather than a smoothed weekly curve.

do not assume reconstitution intuitions apply, there is nothing to reconstitute

Which programme and which readout are you quoting?

replysharereportpermalink
u/the_poster_in_question_20261 point·9 months ago

Nothing containing this compound is approved by any regulator, and research-use-only material is not approved for human use.

  1. Small molecule, not a peptide. Purity discussion here is a different problem.
  2. Cite ATTAIN/ACHIEVE arms specifically when quoting numbers.
  3. Availability speculation must be flaired Speculation.
  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.
