they generally use No dose, which is a legal drug.
Speed in a tablet form is rather rare since the cost to manufacture would increase due to needing a pill press and the time spent to actually press the pills.
Whilst it is true that a lot ofwhat is sold as ecstasy is in actual fact a form of amphetamine closer to speed, mixed with ketamine and small doses of MDMA, MDA and PMA no one really sells speed in tablet form
Perhaps though you are a large part of the party drug scene and i just dont know about it huh?
