[Lab] SGN reta — VendorInvestigate came back 93.7% against a claimed 94.2%

Question Receipts ×6 Slow Clap ×1

Posting this because I searched for it and got nothing useful.

Setup: 0.5mg, week 58, injection-site soreness present but not ruining anything. I changed exactly one variable — constipation — and tracked it for 7 weeks.

Result: a difference, but a small one, and well inside what I would call noise if someone else posted it. So I am putting it here rather than presenting it as a finding. If two or three other people have done the same thing we might actually learn something.

Not medical advice, obviously. This is one person with a spreadsheet.

Titration speed is a side-effect dial far more than an efficacy dial.

resting heart rate moved up 15 bpm and settled back down when I stopped escalating

nausea on day 2 is normal, nausea after week 76 is worth checking

Removed a chain here. The rule is one line long and it is not negotiable.

Respectfully this is a sample of one presented as a finding.

Went to A&E convinced it was pancreatitis. Lipase normal. It was gallstones. Get checked, do not post and wait.

sulphur burps are disgusting but not dangerous, 12 weeks and they stopped

constipation is real, boring, and fixable

Not to be pedantic but hair loss and sulphur burps are being used interchangeably and they are not interchangeable in real life.

Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.

hair loss is real and usually reversible when you stabilize

Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.

the food-noise thing stops around week 68 for most people

Disagree on that part. 98.7% and 98.9% on the same vial is normal.

week 57 and the nausea is finally getting better

Disagree on that part. 97.4% and 95.1% on the same vial is normal.

Yes, exactly this, and it is the bit that took me 95 weeks to accept.

Did the constipation start before or after the dose increase?

Slight fix: the number was 97.2, not 97.4. Decimal point, but a fairly consequential one.

u/amara_haddad2 points·1 months ago

Is that before or after you stabilized your sulphur burps?

Is that before or after you stabilized your sulphur burps?

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.

About c/sideeffects

Side-effect experience and management, with a strong bias toward the ones that are common and boring (nausea, constipation, reflux, fatigue, sulphur burps) and a hard line on the ones that are not (severe abdominal pain, persistent vomiting, jaundice, vision changes). This community is not a substitute for urgent care and the mods will say so bluntly.

c/sideeffects rules
  1. Severe or escalating abdominal pain is an urgent-care question, not a forum question. We will lock those threads with a pointer to help.
  2. Describe your dose, your week number and your titration speed — otherwise nobody can help.
  3. No diagnosing strangers. Share what happened to you.
  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.
