The bibliography

The negative sepsis trial deserves company on the shelf with the more exciting findings.

Sepsis, repair and metabolism

For the central sepsis argument, the useful pair is ETASS followed by TESTS. Their different findings are the reason the thymosin alpha-1 essay spends so much time on that indication.

For BPC-157, the vessel-growth experiment and the musculoskeletal review show the distance between a mechanistic proposal and the human record. For retatrutide, the receptor study sits beside the obesity trial and the diabetes trial. I prefer pairing these very different papers to an easy claim about boosting.

The full list follows: seventeen journal papers spanning clinical trials, laboratory work and reviews. Their inclusion gives the arguments a source, rather than a uniform endorsement of every conclusion.
