week 16 check-in — 11kg down, the food-noise thing manageable, one thing confusing me

Data Well Actually ×4

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

Setup: 10mg, week 94, sulphur burps present but not ruining anything. I changed exactly one variable — cold chain — and tracked it for 19 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.

Germany to Germany: 5 days with BCH and 30 days with GGPeps. Same route, different carriers, variance is real.

the logger trace is the data that matters, not the packaging promises

Customs clearance took 4 days. Package sat unrefrigerated during that. Powder tested clean after, reconstituted solution probably would not have.

Reconstituted or dry powder?

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

stability after excursion is not zero, it is dose-dependent

Half-life is about 168 hours, so steady state lands around week 22–5. Practical consequence: what you feel in week 1 is not what that dose does.

This is correct. Dry powder is way more robust than liquid.

no tracking numbers, no full addresses, no label photos — instant removal

Yeah, data logger is the only acceptable proof.

customs clearance often breaks the cold chain, factor that in

u/ms_fragmenter9 points·1 year ago

Yeah, data logger is the only acceptable proof.

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

About c/coldchain

Temperature and stability in the real world: what an excursion actually costs you, why lyophilised powder is far more forgiving than reconstituted solution, how to read a logger CSV, and how to photograph a failed shipment so the conversation with the vendor is short.

c/coldchain rules
  1. Excursion claims need a logger trace or a photo taken at unboxing. "It felt warm" is not data.
  2. No tracking numbers, ever. They identify you and the recipient.
  3. Stability claims need a source or an explicit "this is my guess" label.
  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.
