Vyvanse is a pro drug that metabolizes into d-amphetamine. There really isn't any "rush" with vyvanse, since taking it orally is the only way it will be active since it requires contact with the digestive tract and first pass metabolism thru the liver. This is why you cannot inject or insufflate vyvanse.
As for dosage, what is your amphetamine tolerance like? If it is low/non-existant, 90mg would be WAY too much.. 90mg of vyvanse metabolizes into roughly 45mg of d-amphetamine (dexedrine pills contain d-amphetamine for reference..)
With no tolerance I would start out with no more than one 30mg capsule. If the capsules already contain powder, parachuting them will not be much more efficient.. Your stomach acids break down that capsule rather quickly. By parachuting the powder alone, you may start the metabolic process a few minutes sooner.
Regardless, there won't be any "rush" and i feel you may be slightly disappointed with vyvanse. Either way, start with no more than 30mg and see where that gets you. You can always take more, but once you take it there is no turning back. ODing on amphetamines is insanely horrible.
My question is by doing this will I get a quicker "rush" not so much a rush but a bigger bang much sooner then just popping tha capsules ? Or is 90 mg parachuting too much at one time ?
