That is not what Shadow is disputing. The ONLY capsules are from UNDERGROUND sources. NOT a doctor, NOT a script.
If they came from a DOCTOR they are NOT underground. She is saying this "doctor friend" gave her REAL SCRIPT VAR - only without a script.
This is simply not possible unless he gave her underground stuff. And with underground, even LEGIT sources, there is ALWAYS the chance of getting the wrong thing.
This is exactly why, no matter HOW WELL you know your source, it is in your best interest to get the shit tested yourself.
