I have been dabbling with MPA now for 2 years on and off. I find it useful for a few things.
1) The best dose for me is small lines, around 3 cm long (sorry i have no idea of the weight of substance). It keeps me alert, awake enough to keep going but at the same time I can sleep whenever I choose to. Having small lines also means 1g of this stuff (which I just order cheap online at 99%+ purity) last me between 2-5 months.
2)It can be taken in every day situations with no noticeable effects to anyone other than myself. I get a mild tickling in my belly, like a mild cocaine feeling I guess. It seems like the equivilent of drinking lots of coffee but without the shakes or side effects.
3) I use it when I work long hours and it keeps me alert for as long as I let it. I feel slightly more brainy too, things that I know tend to make me think first seem to flow more naturally and i get jobs done more efficiently from writing, designing, mixing music, cleaning... all flow a lot easier. I think it makes me focus more on the tasks at hand, multitasking included.
4) I also find it can be used as a dietry drug provided you know what your doing mentally too. For instance, when I'm buzzing about on it I don't really feel like eating and eating seems a chore because I seem more bothered about wanting to be productive (play games, listen to muic, or dust in places i've never bothered dusting before etc). If i need to power through a day and not eat, I can. I tested this when I first used MPA and I lasted 4 days without eating. I felt i could last longer but started getting light headed due to lack of sleep too so found the nearest mars bar and left it at that. However, once I knew the limits, I thought about learning to use it sensibly in the day to prevent me from the urge of snacking and bordom. Over 4 weeks I dropped a size and then stopped using MPA for a couple of months trying to maintain the routine of eating that I had set on MPA.
4.a)I ordered some whilst I was in Vietnam. Custom did hold it back and I had to speak to the manager (obv bricking it at the time) but i played the dietry drug card, i think the "meth" bit was the only thing freaking them out, and they let me take it in the country.
Anyway, I like it. If you can use it sensibly and not become a crazed addict then I feel it has many bonuses...almost like a notch up from the legal Pro Plus
