This follows the opening post rather than contradicting it.

I changed my mind about labelling requirements for research chemicals after someone here asked me for the source and I could not produce one. That is worth saying out loud because it is the ordinary way it happens.

That matches what I have seen, for whatever a single anecdote is worth.

Picking up post #4: that is the part I would want checked first.

Labelling and intended use: a compound sold as "research-use-only" does not change its pharmacology if ingested. It changes the legal status of the sale. The labelling tells you the intended use, not the actual use people make of it.

I have kept the units in throughout, for the obvious reason.

Labelling requirements for research chemicals has been discussed here with more heat than it deserves, mostly because two definitions have been in play the whole time.

I think the labelling requirements for research chemicals question is answerable and has not been answered, which is a more optimistic position than most of this thread.
