^^ I agree totally, Berroca is great. In the mad coke days of long ago, someone suggested that berroca were invented solely for the coke market, as they not only replaced what you lost in minerals (don't know about this) but the container itself is perfect for storing coke.
A mate once stashed his coke in a Berroca, and buried it in the garden. Waking the next morning to torrential rain, he went out to find a stream running through the garden where he'd stashed his stuff. His eyes followed the water down to a drain where he saw his berroca bobbing around the grate. After cleaning the outer, he opened it to find things were as dry as he left them.
I use a combination of things, including tryptophan when I have it. Berocca's are great, but something I found better is an Orthoplex formulation SFM. I bought this after the PAN fiasco, when I was looking for tyrosine. It was the only preparation they had at the time which contained tyrosine, as everything else had been recalled.
That was a good find. These little beauties really pick you up after amphetamines; meth or MDMA (with our usual low dosages and infrequent use). It contains B6 and a litle C, with tyrosine, methionine and magnesium aspartate to name a few.
Anyway, we've both found these are like a recovery pill when taken after a hard night with little sleep. I try to alternate my daily vitamins between berroca and SFM.
There's some other noted qualities about this formulation, but I'll do some testing with individual components before I make any wild assumptions. One thing I'll will say; I notice a drop in my core temperature and perspiration rate after taking stimulants followed by a SFM. More to come...
