Stimulants dexamphetamine and speed

[hollandhomeboy]

hey all.

ive used dexedrine before to study. i'd take one or two pills (5mg, not XR) and be good for 4 hours of study.
im going to acquire some dry speed which tested at 62% or 64%... i was wondering what the equivalent dose of this speed would be to a 5mg pill of dex.
my intention is to use this speed to study.

also, how much would be enough for studying? one bump? two? i'll prob take a bump or two more like 2 or 3 hours later but yeah i guess hypothetically for one study session, if i were to dose just once, how many bumps would on average suffice?

i have 1.5 weeks to study and then 1 week of exams. im hoping to be able to not gain a massive tolerance but that's prob unavoidable.

i have no tolerance nor am prescribed to any dex.

thanks all

well, is it 62-64% dextroamphetamine according to the source? Or does it include Levoamphetamine as well? Also, is it the source that told you the purity, or someone incredibly reliable like a friend that has access to equipment which could test for purity?
I ask because if its a mixture of the two isomers (dextro and levi), it depends on the ratio (adderall is only 25% levoamphetamine, and sometimes that can be a bit overbearing, especially with larger dosages, I wouldn't want to use speed that contained say, 50-75% levoamphetamine. We also need to know how much 'dry speed' you're getting, is it 62-4% of a gram or what?

If its just dextroamphetamine and 36% cut (which i imagine it isn't just dextro) than you'd just have to basically do the math if you want an equivalent experience that you had with 10mg of Dexadrine(granted this is genuine amphetamine, not methamphetamine or some RC amphetamine or other stimulant).

At 6.4mg/10mg, and equal dose (to 10mg of dextroamphetamine)- (IF this is the actual purity), would be around 15.5mg. However, unless you have a way yourself to prove that its dexamphetamine and not some other stimulant which could he a LOT stronger (dosing that high with MDPV for instance could be a big mistake, and if it were somehow methamphetamine instead, it would be 2-3x more potent). Either way, you got to get a scale...thats the only way to dose unknown chemicals with any sort of accuracy. I also would do an allergy test with one or two milligrams first to make sure you havn't been sold something super potent or that you react badly to.​

does that mean that 1g is less (or more) potent than 2g? 62-64% of a gram? i thought that no matter the quantity if it tested at that range it meant that all the gear would be the same.

one of us two isnt following the other (most likely me noob) but i USED to take dex. 5mg pills. scripted, from the bottle so it was legit.
NOW im getting JUST amphetamine. it was wet (as ive been told amphetamine usually is) and has been dried. that tested in that 62-64% range. legit testing.

i think you get my question tho, so it remains for you and anyone else. so far thanks for putting up with my noobness and for the help!

no I apologize, I realize it doesn't really matter, at all, as long as you can measure it with a scale, cause the only way you could convert dexadrine to street speed is if you do some simple math, and its easier it you say, have 1g (cause thats a 1000mg, which would mean 620-640mg is of pure amphetamine. It would make things a lot more difficult if you had some weird amount like 872mg, cause the math would be harder (well maybe not, I'm especially bad with math). But yeah, disregard that part of my post.

Well, being from america and not knowing much about the speed sold over there (as opposed to methamphetamine and pharmaceutical dextroamphetamine), I did a little bit of research and it seems that most street speed is Amphetamine Sulfate, and is equal parts Dextro-amphetamine AND levoamphetamine. So its like Adderall with more PNS stimulation and some other additional adulterants. I know that 7.5mg of Dexadrine (dextroamphetamine) is equivalent to about 10mg of Adderall(mixed amphetamine salts, 75%dextro, 25%levo), so I'd imagine that if this is amphetamine sulfate, 10mg of unadulterated sulfate (with an equal ratio between dextro and levoamphetamine), would be equal to 5mg of dexadrine (dextroamphetamine). However, since its only about 62-4% amphetamine, you'll have to do the math, but I'd think then that 10mg of dexadrine would be something like 32mg of street amphetamine. (Or 3.2mg of Dexadrine would equal 10mg of amphetamine sulphate). Please somebody correct me if I'm wrong with this math or got lost somewhere.
