the excursion thing finally clicked for me and I want to write it down

Discussionbranch of 7 comments

Confession thread, sort of. I went from 2.5mg to 1.0mg much faster than I should have because the scale had stalled and I got impatient. The stall broke about 3 weeks later, at which point I had no way of knowing whether the dose increase did anything or whether it would have broken anyway. So now I have constipation…

Logger trace from my shipment: 4 hours at 15°C.

excursion claims need a logger trace or a photo at unboxing, not "it felt warm"

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.
