That makes sense. And is really a great idea.You are completely right.
One overdosed and one underdosed will get you there.
I usually filter all into a 100ml vial and send 1ml from it.
However i noticed that most people buying US Dom gear are adverse to filtering and buying new vials which is why i didn't suggest it.
For the CN threads i usually always suggest filtering+100ml vial because they're kind of used to filtering lol
