Mixing pills with molly

[curious_george1]

I was just wondering if anyone knows about mixing pills with molly?
someone i know has a festival coming up and wants her roll to last for a long time(6-8hrs) and i was curious to know if mixing pills (probably high in amphetamines) and MDMA caps is a good way to make her roll last longer? Or if not how many pills and in what ratio of time should she take if she wants to roll all afternoon

She's only rolled 2 times with more than a month in between each time
Thanks

it's generally not a good idea to mix different pills/powders if you're not sure of the contents. they might be adulterated with different substances, making the possible interactions an even bigger unknown.
if you already know that the pills are adulterated, then why not just take the mdma caps?

a good roll of 8 hours is pretty much impossible to achieve. the more often you redose, the more side effects appear as the euphoria diminishes. also the aftereffects will be much more pronounced. ime 6 hours is the absolute maximum you can do, if you want the good effects to dominate, and even then, you'll rather be a confused, gurning mess by the end of the evening.
optimal dosing is one redose at 1-1.5h after the initial dose. this will usually yield 4-5 hours of fun.
