I have never heard of their tabs coming underdosed-do you have any proof? I know someone tested their EQ- and it tested a little stronger than labelled. british Dispensarys on the other hand has some quality issues.
I don't know of anyone who paid money to send their tabs in for analysis.
I just know people who use their tabs and report back they are weak and underdosed compared to name brands and other UG gear.
Experienced gear users know when something isn't up to par, they can "feel" it.
I have no idea about the quality of their injectibles.
