Reconstituting a multi-strength kit without mixing yourself up Writing it up because I had to work it out twice and would rather nobody else did.

I have spent a fortnight trying to pin reconstituting a multi-strength kit down and I want to set out where I have got to, because I suspect the honest answer is duller than the thread this will produce.

What I have: a consistent observation across a small number of cases, collected the same way each time. What I do not have: any controlled comparison, or any reason to think my cases are representative.

The specific question is whether the pattern survives once the obvious confounder is removed. I cannot remove it with what I have.

What I would want before treating reconstituting a multi-strength kit as settled: the method, the sample, and whether anyone tried to find the opposite result. Two of the three are usually missing.

KStephanopoulos, post #4: Appreciated. The plain phrasing does more work here than a longer post would. Go to post

Confirming post #18 from a second method, which matters more than confirming it from a second person.

I keep a log for reconstituting a multi-strength kit specifically because my memory of it turned out to be systematically wrong in one direction. Six weeks of notes cost nothing and settled it.

Useful. I had the fact and not the reason, which turns out to be the important half.

Reconstituting a multi-strength kit: 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.

r.novak, post #43: I disagree with the framing of reconstituting a multi-strength kit above, and I think it is a substantive disagreement rather than a terminological one. Setting out why, so it can be checked. The reasoning depends on an assumption that is doing a lot of work and is never stated. If the assumption holds, the conclusion follows. I do not… Go to post

Do not shake. Swirl, or leave it. Vigorous agitation introduces air and shear, and neither helps a peptide go into solution any faster than patience does.

I have left out the parts I could not verify.

Understood. Thank you for being specific about the limits of it.

Building on post #105 rather than restating it.

Reframing reconstituting a multi-strength kit slightly, because I think the disagreement is about the question rather than the answer. If the question is "does it happen", yes. If it is "how often", nobody here knows.

Taking reconstituting a multi-strength kit seriously for a moment rather than deflecting: the honest position is that the community has observations and no controlled comparison, and those two things support very different sentences.
