Exercise transformation with training: went from barely able to walk a block to completing a half marathon last Saturday.

Exercise-induced nausea amplification with training: I learned the hard way that intense exercise within 12 hours of injection can make nausea much worse. The combination of delayed gastric emptying + exercise-induced blood flow redistribution is rough on the GI system.

My workaround: inject Friday evening, do low-intensity activity Saturday, and save my intense workouts for Tuesday-Thursday when the GI effects have subsided. Timing your training around your injection schedule is a real optimization strategy.

One concrete data point for the thread. Say what you would expect to see if you were wrong, before you look. It is a small discipline and it changes what you notice.

There is a second half to this that has not been said yet. The distinction that resolves most of these threads is between what is true on average and what is true for one person. Both are real; they answer different questions and get quoted as if they were the same one.

Following on from DerekSJ_a1c — and this may be the naive question:

What would you measure differently if you were starting again?

Closing the loop on my own question.

Late follow-up. I did not do what was suggested, I did something adjacent, and it worked; posting the difference in case it matters to somebody.
