Adding the measurement that the opening post says would settle it.

Thymosin alpha-1 has a regulatory history in several jurisdictions and a real clinical literature, which puts it in a different evidential category from most of its neighbours here.

Everything in post #5 holds. The case it does not cover is the one I have.

Checked the research-use-only status claim against the primary source this morning. It survives, with a narrower scope than the version quoted here. Posting the narrower scope.

Picking up post #11: that is the part I would want checked first.

Research-use-only status: I have looked for the primary source twice and failed twice. Either it does not exist or it is somewhere I do not know to look, and I would like to know which.

Reading back through the research-use-only status threads from last year, the same three questions come up every time and only one of them has ever been answered properly. That seems like a documentation gap rather than a knowledge gap.

The confident answers on research-use-only status and the well-sourced answers are not the same answers, which is the most useful thing I have learned reading this category.

Adding what did not work for me on research-use-only status, since the failures never get written up and they are half the useful information.

The useful distinction on research-use-only status is between what was measured and what was inferred from it. Both end up in the same sentence and only one of them has error bars.

Genuine question rather than a rhetorical one: has anyone here actually observed research-use-only status, as opposed to read about it? The thread is long and I cannot tell.
