Sir:
Here is my query:
I am ruminating on a pharmaceutical product [$$$] - Percoset.
Are you acquainted with said product? I am actually not interested in the company, brand, or descriptions thereof; I am asking you to enlighten me as to its qualities, for better or for worse, as one scientist to another.
Were I to offer you an analogy, as I am about to, perhaps it would go something like this: "Percocet is to Oxycontin, as Tylenol is to 800mg Ibuprofen..."
... And, now, I beg off and ask for your hastiest assistance. Please respond to my email, attached [somehow or another].
Sincerely,
J.A. Mitch
