compared to undergound stuff (even though they are technically underground), its like night and day.
i dont have alot of experience though, so i cant compare it to much.
there are lab tests on the net that show all of their products are accurately dosed, some even OVERdosed (mg per ml)
it can be painful if you inject it too quick
it comes in 5ml satchets, but they normally contain 5 1/2 or 6 ml
