True, with the qualification that this is a self-selected group. The people for whom it did not work post less, and that shapes everything we think we know.

The pharmacokinetics explain nearly every practical question asked here.

Thank you — that is the clearest version of this I have read, and I have read a lot of them. Adding it to my notes with a link back to this thread.

I am going to disagree with the direction of travel here. The thread has converged on the tidiest answer rather than the best-supported one, and those are not the same thing.

Moderator note: a post naming a supplier has been edited. Discuss suppliers in the review sections, not here. Report rather than reply if it drifts again.
