With that said. I would assume that yes, you can. Almost anything can be done in chemistry. If a drug can be synthesized, I believe it would only make sense that you can reverse-synthesize. If a chemical reaction can happen within the body then, in the right conditions, it can be done outside of the human body. However, this would take knowledge in chemistry, accurate resources for information, most likely lab equipment, Tripsin enzyme, and Lisdexamfetamine. Even thoough I sound intelligent, the other answer

er seems to know more than myself about tripsin.

I personally wouldn't reccommend it. Vyvance is a slow-released amphetamine that can increase heart rate and blood pressure. Extenze works by routing more blood to penile tissue and increasing pressure. People in the past have been rendered impotent for long periods of time by mixing exctacy (another amphetamine-based drug) with male enhancement products and causing overpressure. That being said, the mixture will make for a more intense, longer-lasting experience, but it may have dire consequences.

Concerta and Vyvanse are both extended-release central nervous system stimulants. Combining stimulants can increase the risk of cardiac events, cause high blood pressure, and other life-threatening side effects. Only take this combination if your doctor has prescribed both medications to you.

Essentially speaking, "meth", adderall (and other ADD meds), and cocaine are all made up of the same stuff, called Amphetamines. The only difference is their mechanisms of action, which are not yet fully understood. The 'meth' in methamphetamines is an extra molecule which binds on to the amphetamines and makes them last longer in your body. http://en.wikipedia.org/wiki/Amphetamines

Naw dude im super high on 440 mg right now and i threw up twice within the first hour, but since then ive been flying. If u can get past the nausea and vomit you will be fine. I like to think of the vomit as no pain no gain lol. Wow im a junkie 4 real

DON'T DO IT! Technically you can, but Excedrin migrate has caffeine in it, enough that when I took it while on vyvanse, my heart was racing and I could not stop vommitting. If you can drink a bunch of coffee while on vyvanse, you probably won't have an issue with the Excedrin migrane, but be careful when taking too many stimulants at the same time.

Drugs tests are not 100% accurate and can give false positives and false negatives for various reasons. To prove that you have not taken diazepam, ask to take an alternative form of test.

That depends on the person and the history with medications in the same pharmacological category. Because of these variables there is really no correct answer to this question, it could be a month... and iy could be ten years before a tolerance is built up.

yes!! it can be fatal!

Vyvanse is lisdexamfetamine, while Adderall is dextroamphetamine, aka (a-methylphenethylamine). Vyvanse is a pro-drug for dextroamphetamine, meaning it is only active after you eat it, so there is little to no abuse potential. Basically, Vyvanse is dextroamphetamine bonded with lysine (an essential amino acid). The euphoria experienced with 50mg Vyvanse orally, is comparable to 25mg Adderall orally. However Adderall is active through insufflation (snorting) so I would assume the euphoria would be better on Adderall.

Fentanyl will show up as fentanyl but this is almost never tested for. It is a special test which is also expensive and I would only suspect it being tested for if one had access to it, i.e. anesthestiologist.

no it does now

Generally speaking, no; Vyvanse is a pro-drug for the stimulant dextroamphetamine. The effectiveness of amphetamine should be apparent immediately as it does not require time to build up in your system unlike other medications. In some cases, certain negative side effects will wane as a person continues to take Vyvanse. As with all medication for ADHD, it works best with lifestyle counseling and behavioral changes.

Stimulant medications, including amphetamines (i.e. Adderall, Vyvanse), do induce anxiety in some people. Other medications could be tried for treatment of ADHD if this anxiety is unbearable, or another medication could be used to treat this anxiety (i.e. a benzo or a mood stabilizer).

That is pretty much my concoction minus Klonopin. I've found no interactions between the Lexapro and Vyvanse. Gabapentin, however, seems to lessen the benefits of Vyvanse, shortening its duration. The Klonopin, interestingly, has very little interaction with the Vyvanse but it helps with the crash.

My experience alone.

Provided you have read the drug information sheet with both products and it does not warn against taking one product with the other, when you take makes no difference since both are time realeased....but check with the prescribing doctor(s) first is always best.

That depends on what the prescribing physician and/or primary care provider decides.

That being said, Xanax (alprazolam) and Vyvanse (lisdexamfetamine) have no known drug to drug interactions and can be taken safely together.

If is completely fine to take the drugs Clonidine and Vyvanse. Clonidine will help you with your sleeping problems.

I read on 1 website that you open the capsule, dump the powder on a plate, put it in the microwave for a minute, and u will have something that is worth snorting...but I definately want to get more information about this before I even consider wasting a pill on this, I have opened the capsule and dumped the powder in a glass filled about 1/4th full of water, then stirred it up until the powder fully disolved and then drink it, this seems to make the meds kick in quicker and I know for a fact that this works and is not a waste of meds.

Vyvanse is Dextroamphetamine (a stimulant) coupled L-lysine (an amino acid). Which is known as Lisdexamfetamine.

There are no known drug to drug interactions between these two medications, making them safe to take together. Make sure to contact you primary care provider prior to taking these two medications to ensure that it is safe.

The prescribing information mentions there is no problem with opening capsules. Adjusting dosage is something that should be done with a physician supervision only.
