Agree with Perforated, big diff between H and speed. If it's meth and it's fishy, then it's just got some methylamine left in it giving it that smell. That's def sounds like it came off an old skool recipe.Just had something very, very fishy. Disgusting taste, basically could have more or less been mephedrone or heroin. Or just old-school crank. I have to stop doing this.
