I would stray away from Phenazepam. Phenazepam has a half-life of up to 60 hours and an onset of effects is approximately 2-3 hours following oral administration; due to this, there is a potential for users to re-dose prior to the observation of its effects. Phenazepam also seems to have zero positive recreational effects, similar to Diclazepam.
Etizolam is a safer alternative in this regard. With a doses starting at 1-2mgs and a half life of 3-7 hours it's much more ideal for recreational and some therapeutic uses. If you can wait up to 4 hours and not wanna redose than maybe give phenazepam a shot. idk. Seems good for mild-moderate anxiety. Didn't help mine but i have severe GAD, Panic disorder and PTSD. Clonazepam, Alprazolam, and Etizolam seem to be the only Benzos that help.
