Loose evidence is not nothing, but a washout either side is the only reason to trust your own take.

Cold storage, light protection, date on the vial. Boring, removes half the variables. Not on agmatine but the pattern is familiar.

Enteric coatings should not be crushed. The pellets are the delivery mechanism.

The declaration contradicting the return address is what gets it opened. Currently on the de minimis threshold myself.
