[Data] logger trace: 6 days transit, 41 hours above 8°C, powder was fine

Data Well Actually ×7

Week 84 update. 25kg down from the start, reflux basically gone since about week 41.

Things that worked: consistency, protein at breakfast, walking more than I want to. Things that did not: everything I bought on the internet to help with reflux.

The part that surprised me is how much of this is admin. Ordering, storing, logging, remembering. Nobody mentions that the hard bit is not the drug, it is the routine.

Happy to answer anything. Please do not ask me what dose you should be on.

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

Yeah, data logger is the only acceptable proof.

That is net peptide content, not purity. Different number, different meaning.

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

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

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

Spain to Spain: 21 days with QST and 29 days with FGP. Same route, different carriers, variance is real.

Adding to this: packaging is doing more work than the comment implies.

Reconstituted or dry powder?

Peak temperature and how long at that temperature?

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.
