[Results] 66 weeks on 10mg, full numbers, ask me anything boring

Discussionbranch of 17 comments

Right, the cold chain question again, but with numbers this time. I have 15 data points over 30 weeks. The pattern is consistent enough that I do not think it is chance, and boring enough that nobody is going to screenshot it, which is usually a good sign. The thing I would flag for anyone new: the effect I am…

data logger is the standard, gut feeling is not

This is the "correlation is mechanism" thing again. You changed three variables at once.

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

France to France takes 22 days on average, variance is 30 days

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

gel packs last 20 hours, after that you are relying on the box itself

time-at-temperature integral is the dose, not just peak temperature

France to France: 8 days with FGP and 35 days with TFC. Same route, different carriers, variance is real.

lyophilised powder is far more forgiving than reconstituted solution

Disagree on that part. 99.2% and 99.3% on the same vial is normal.

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

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.
