Actually it is available in the US.It falls into one of those legal grey areas.
I bought mine from the US and had it sent to Aus.
Although procaine is a banned import substance,for some reason customs open and check and let it through.Maybe the other ingredients and the fact it's sold as a nutrient makes the difference.It also falls into a legal grey area in Australia.
I feel that it is
drug.I really don't know how they market it as a nutrient.
The reason I tried it had nothing to do with life extension or health properties.
As I suffer from fybromylagia,I was looking for something that may have an effect on very mild pain.
It did somewhat have an effect.I would take it again in certain situations.I, however, don't take it regularly now.I never took it for large periods of time.
I also bought it to experiment with mixing it with other "nutrients" (l-dopa herb etc) to see if I could find some extra energy.Most of my combos work, but only for short periods (days to weeks).
To me,it's a strange substance to be marketing.It made my skin look good(smooth,tight etc), so maybe it has some use other than what it is sold for.
