Take it from me, leave the cyc alone.
1 it was best taken with amps (either morphine or phy)
2 orally it will do fuck all except prepare you for a long ferry crossing (they are travel sickness tabs)
3 your veins won't last long and if you hit a artery as I think you have done before (unless I'm getting u mixed up with someone else) your going to loose that limb, no ifs or buts.. Loads in St. Helens and Warrington got no arms/legs/fingers.
They are like dicanol when hit with a opiate, which was the holy grail of dda boxes and terminal cancer patients around here. Sadly gone now or rare as rocking horse shite.
The only safe way to bang cyc is cyclamorph amps or cyclizine amps (didn't know they existed until a light fingered chemist passed me some, which just got threw away cos I couldn't handle the shit anymore).
