[Question] how do you actually verify rodent data

Question

Confession thread, sort of.

I went from 5mg to 1.7mg much faster than I should have because the scale had stalled and I got impatient. The stall broke about 19 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 muscle cramps I did not need and a data point I cannot interpret. Two lessons in one.

Posting it in the hope that somebody at week 18 reads it before doing the same thing.

I love that this community will spend 40 comments on a detail. That pedantry is why the numbers here matter.

This is correct. The naming is genuinely confusing.

regulatory status changed in 8 countries, check yours

Yeah, rodent data does not scale to humans.

Stalled for 11 weeks, changed nothing, and it started moving again on week 86.

pentadecapeptide is tendon, the supply chain naming is a mess

research use only, no human protocols, no injection instructions

Strongly agree. Zero human controlled data.

the sequence literature looks promising but rodent-only

Yeah, rodent data does not scale to humans.

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

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

Did anything else change in the same window?

near-zero controlled human data, full stop

About c/bpc157

BPC-157 as it actually is: a pentadecapeptide with a genuinely interesting rodent tendon-and-gut literature, near-zero controlled human data, a naming and sequence mess in the supply chain, and a regulatory status that changed sharply in several countries.
