I know this is an ancient thread, but in case anyone reads still: Cyclazadone isn't terrible in a pinch. Depending on liver metabolism, I guess there's a 1 in 10000 chance it could be a false positive, but I've not experienced that.
It's basically like an aminorex, and if I remember, it's sort of related to pemoline, but was 3 or 4x more potent with its dopaminergic nature.
It's a nice little functional stim, I usually take it oral ROA. Anyone not a heavy stim user would be best served at 10-15 mg to start. I'll usually sit at 40, maybe 50. Just make sure you aren't doing it every day, and if you're going to be remotely frequenting it, take TUDCA, milk thistle, NAC... Really just general amph liver protect protocol.
