Stability of BPC-157 in solution: what has been measured

Stability of BPC-157 in solution: what has been measured — setting out what I have, and where I think it stops being reliable.

Comparing STEP 4 (JAMA, 2021) with FLOW (N Engl J Med, 2024) and finding the comparison harder than it looks.

Different populations, different durations, different endpoints defined slightly differently, and in one case a different estimand. People compare the headline percentages anyway, including me until recently.

Is there a defensible way to put these side by side, or is the honest answer that there is not and we should stop?

I disagree with the reply above, and I think the disagreement is substantive rather than terminological.

The distinction being drawn does not survive when you look at the published data for this specific question. I would be glad to be shown wrong on this, because the version I am arguing against is more convenient.

Publication patterns in the BPC-157 literature: a large proportion of the evidence comes from one research group. That is not necessarily wrong — one group can do excellent work — but it is worth noting when evaluating the breadth of support for a claim.
