Are you talking about what to ask a supplier when purchasing products in person
instead of online?
If online, the price list will tell you the amount of ml and the mg per ml.
If asking in person, you'll have to ask them how many mg per ml
they are. I don't think age matters much, I have used long expired products and they
worked fine. Of course you have to ask what type of AAS, you know what
you want to use for your cycle, correct? Maybe I misunderstood that one.
Or maybe you meant what UG brand it is? If so, just ask them what the brand is
or who makes it.
