im down in mlbourne, sydney and melbourne get pretty much the same shit.
speed and ice are pretty different in the sence of scale, visuals etc. ive bought 'speed' in the past from all over melbourne, city to outback, and all the good speed was brown, sticky crystaly lumps, witch refused to burn properly or much but when i/v'd was better than any other looking speed. the best ice/shard(whatever) is either powder or crystal, burned for hours and lasted for days. if you were to try to smoke a point of speed down here, it would burn badly, some crystally speed burns alright with a crapper high than the average shard.
im just saying this to clarify that down in melbourne and probably sydney, ice and speed are to an extent, different drugs with different effects.
and powder shard is indeed just as potent as crystals.
speed=amphetamine shard=methamphetamine, there a slightly different drug, there a chemical formula is different and there reactions to the body are kind of different.
and speed is made differently to shard, people who fuck up the shard or overcut there shard have shit shard not speed. theres a differnece.
people dont work out how to fuck up there meth recipie perfectly to make potent as fuck speed..
