I was fortunate to win a contest that /u/SupremeG3722 held. I placed 2nd. SG3722 is a reseller of quantik bars (3.5mg).
The package arrived in 3 days after SG3722 told me it was shipped. He uses adequate stealth/visual barriers, pretty much the same stuff as the other Q/LX resellers. You'll have to go through a few layers just too see the bars (A+). I received all bars intact, zero dust (another A+).
I tried a half bar (as indicated in the pic) and it was definitely more than 1mg. The half bar felt close to the potency of a whole bar from barbarossa's bogo batch of pfizers.
SG3722 seems like a straight shooter, his comms are on point and with Q's bars you cant go wrong.
