Drug info - Blow Up Caps

[Mish]

SWIM was sent a 4 x "Blow Up" caps for free along with an order from a certain vendor-e-mart...

SWIM never takes these things usually as it's mostly just caffeine or guarana or taurine and l-somethingorother or sida cordifollia(sp) and it's all a load of crap really.

However, SWIM received them free and was just wondering if anyone had tried them by any chance, and if they actually did anything?

They are apparently...

"An energiser for a long night and/or sharp working days"

and the ingredients consist of the usual:

Griffonia simplicifolia extract, Bioperine, caffeine, L-tyrosine, ginger, vitamin C, vitamin B3/B6, siliciumdioxide

The only two SWIM has not heard of are Bioperine and siliciumdioxide, and was wondering if anyone could shed some light onto these ingredients and their effects. Similarly, if anyone has had any subjective experience with these Blow Up Caps then how'd it go?

SWIM is not expecting any glowing report, but any vaguely stimulating Legal that actually works is always useful to know, perhaps for study motivation or after a heavy night out. Either way, information appreciated
