Stimulants Street Amphetamine vs. medical dexamp

[sir_thizzalot]

I couldn't find an answer- how is vyvanse(dextroamphetamine), comparable to street amphetamine sold in tabs(as an example, : http://www.pillreports.com/index.php?page=display_pill&id=21404 , and eckos, from Quebec apparently. NOT TRYING TO HAVE PILL I.D. HERE, JUST USING AS AN EXAMPLE). I'm talking about amphetamine NOT methamphetamine. If someone could compare effects that'd be great..(and I don't see why they would, but would street amp. make my pupils dimes(which vyvanse obviously doesn't)?). If someone can show me a thread just like this please do and end this thread.

Vyvanse is a time-released pro-drug available only up to 70mg. The stuff on the street should just be straight amphets (minus cuts and what not) and should possibly be in higher doses as well.

I know what Vyvanse is, and you didn't answer anything I asked really..

Heh...let's chill out.

If you're in the US, but perhaps for those in North America in general (Quebec, right?), street amphetamines are almost always d-methamphetamine. For those in Western Europe, it's nearly always racemic amphetamine, and then in Eastern Europe, it's often racemic methamphetamine but you also see racemic amp rather often.

IME, amphetamine will not 'saucer' one's pupils, and meth will only do so when one takes an inordinate dosage (which many meth users do). For me, though, it's mainly serotonin action that dilates one's pupils. Theoretically, though, there should be some dose of most any classical stimulant that causes pupilitary dilation.

These were all around Quebec along with pills from the same press, and some floated over to where I am.

It's not d-methamphetamine, though, that is the point of them(that they are amp. but not methamp.), and I am sure about that.

I'm probably not getting them actually, but I still want to know out of curiosity.

Well, PPA and open sale of P2P are banned in Canada like they are in the US (I'm not quite as sure about the latter). Without these key precursors, you tend not to see clandestine amphetamine or racemates (but rather d-methamphetamine via ephedrine). Well, stereoisomer-preserving syntheses from phenylalanine are possible.

How are you sure that these pills have amphetamine rather than methamphetamine? The two feel strikingly similar, I think (although it seems that you haven't bioassayed them). A Mecke reagent cannot distinguish the two. Could the Simon agent?

Apparently, lots of people in Quebec use amphetamine to get work done and all that type stuff, way more than other places. They apparently don't like methamphetamine for this as much, so this ecko press was the normal amphetamine they like. That is what my friend was telling me, and I checked out pillreports and people were saying the same thing about this press(not methamphetamine).

I haven't tested pills in a while. I think madelin only flashes green for methamphetamine not amphetamine. If I can get another test kit(the one that me and two friends were using is out), I can try this, and I'll make sure to check that that's true first.

What's the difference between regular adderall and street amphetamine?

 

[Cloud_9]

Perhaps this might help for dose comparisons:

"A 25 mg Vyvanse capsule would be molecularly equivalent to a 10 mg Dexedrine Spansule (both are about 7.425mg dextroamphetamine base), although a 25 mg Vyvanse capsule is not commercially available.[citation needed] However, the molecular equivalence ratio does not mean that the respective doses of Vyvanse and Dexedrine XR (Spansule) are bioequivalent because the two formulations have slightly different pharmacokinetic profiles. For example, while the area under the curve for the aforementioned pharmaceuticals is equivalent, the peak exposure (Cmax) to the active compound dextroamphetamine is about 50% higher for Vyvanse than for Dexedrine XR.[4]"

-Wikipedia

But as for the differences between this and "street" amphetamines; I have found Dextroamphetamine (What Vyvanse turns into) much less tweaker-friendly. I have had friends who have taken like 200mg of d-amphetamine who were extrenmely heavy ice-methamphetamine users and didn't enjoy it as much because they say it didn't force them to do something; ie. re-arrange the garage and then put it back the way it was etc.

Basically:

Pharmaceutical Stimulants: Measurable doses, Less jittery, More mental focus, "less" physical activity pushiness street-amps tend to have, No cuts in your product!

"Street" Speed: With the non-crystal methyl-amphetamines it is very easy to introduce similar cuts which could be anything from caffeine to pseudophed to lactose, Huge sketch-factor (for me) which is great for dancing I suppose; not so much for home/school-work and daily life's requirements. It is almost impossible to dose street-speed properly unless you know the purity and have a scale with you for dosing; which is impractical. Some dealers stomp their shit hardcore and others may not, even if you do get a good product I find taking too much can actually destroy the ability to use it for ADHD concerns; you all know "that" person who won't shut up about nonsensical jibber-jabber.

But any other questions you want help on you can PM me; or if you are a greenlighter, you can use the AIM icon to grab my screen-name and hit me up there "FlyWithCloudNine"

Adderal contains 4 different preparations of amphetamine, all of which can be seen here:

http://www.medicineonline.com/drugs...ingle-Entity-Amphetamine-Product-Rx-only.html

But it is well known that Adderal is 72% d-amphetamine and 28% l-amphetamine whereas with street-speed you have no way to tell in practicality unless you use two polarized lenses and what amount of the product is the "worthless" (l)levo-isomer, or how much is the (d)dextro-isomer.

Basically levo can't cross the BBB effectively and won't induce euphoria or other mental affects but just force your body to stay awake; there is a reason why I can go spend $4 and get a tube of "L-Methamfetamin" which is just another weird way "Vick's" spelled the chemical. Anyways, street is usually about 1/2-1/2 OI would think? Unless you have a source who would isolate it? I can imagine no reason to isolate the l,d isomers unless its for personal consumption because l-amphetamine itself would make a great cut anyways...

Refering to my above post; Vyvanse is claimed to be about the equivalent so that: 25mg Vyvanse = 10mg Dexedrine.

For those in Western Europe, it's nearly always racemic amphetamine, and then in Eastern Europe, it's often racemic methamphetamine but you also see racemic amp rather often.

This has been my exact same conclusion based on my own world-wide travels. "Amphetamines" in the western European countries (Ireland, U.K., France, Germany, etc) usually will get you some d,l-amphetamine whereas if you are asking this somewhere in Poland or Ukraine, you will most likely be getting some very high quality d-methamphetamine. But once you reach Moscow there is another odd switch where you again are treated to d,l-amphetamine when asking for "amphetamines" or "speed."

Maybe the precursors for amphetamine compared to methamphetamine are just more available in Russia? I can imagine being one of the largest suppliers of industrial chemicals in the world; it would not be too difficult to obtain just about anything one could need for a synthesis. I think the issue is that the reduction of psuedophedrine isn't nearly as to go about doing as I'm almost positive it is a prescription only drug there.

Thank you! I get it now. I'll probably try one of those Kyles just from curiosity now.
