Before phase_dancer cleared up this funny talk on ketone-meth and psudo-meth really meaning dextro methamp and racemic methamp I thought you guys were saying ketone-meth meaning the beta ketone of methamp ie. methcathinone.
I have only a little experience in street speed products but I have seen at least 3 distinct products (usually cut with MSM). Here's a rundown of the the products I have seen in the past. Please feel free to let me know what you think they are ect.
I've had a yellowish orange rock in Melbourne similar to the coca-cola rock in the picture from last page. I thought this stuff was methcathinone. Regular users of shard (methamp) didn't rate the feeling from this stuff even though it kept them awake and was strong enough. I have only seen pictures of methcathinone being a yellowish or orangey rock and heard it has a strong smell. This stuff sure did. A lot of the smell vanished after storage but it still had the cat piss smell when smoked. It got my heart really racing like shards (methamp) but didn't last quite as long and was not so fun. I was very awake but more a tweaked out paranoid kinda feel and made my vision a little blurry. Is this stuff methcathinone? It would make sense if it is around amid an absence of more quality product if it is methcathinone as the guides on the net describe it as easy enough to cook in your kitchen with minimal ingredients.
The other stuff I've had is the general white or yellowish white gooey powder. Nice sweet smell and sweet flavour to smoke (this could be moreso from the MSM not sure). The stronger the stuff usually it's usually more gooey and burns for much longer without so much frosting the pipe (I think this it simply base that I have seen in Sydney but just cut with MSM). I've only eaten base in Sydney once and gave me a similar warm, fairly relaxed, chatty feeling. Smoking this powder speed doesn't make my heart pound like crazy (as with shard). If I do it as home in a relaxed enviroment, I usually feel, warm, relaxed and even a sleepy after smoking it but still awake. It lasts the shortest of the 3 but I find I if I top up regularly I can stay awake for days on it without all the paranoia/sketchyess/worn out feelings of shard (methamp). I believe this stuff is amphetamine probably amphetamine freebase.
Lastly there is shard, I've seen it as clear/translucent long thin crystals I've also seen it as shorter crystals like long rice grains with a yellowish tinge though this was weaker. I've also come accross powder speed that appears by look and by the amount of frosting of the pipe to be high in MSM yet this is strong speed and last a long time and with more anxiety/paranoia. I assume its shard crushed with a lot of MSM. All in all shard, at least the more pure looking clear crystal stuff is not to my liking. I get a pounding heart. Usually I get a rush from the first smoke that makes my head feel spacey and really dizzy but only for 20sec or something. I then feel very alert, clear headed, serious, anxious, paranoid, can't relax or calm down. There is more or a serious feel than the gooey speed above (wich is more fun). I often feel like it upsets my stomach too. No further top ups and I am still awake for 10-12hrs from only a little. I usually feel very dirty, worn out and sketchy around 6-8hrs after as I just can not relax despite all efforts. I would guess this is methamphetamine.e
