NickS,

Have you ever looked into natural testosterone boosters? I ask because when I used to lift and we'd read the labels of the newest supplement...it was always made up of extracts from stuff that we were able to find at ethnic supermarkets and Asian herbal stores.

There has to be some native plant out there in NZ that you can use.

I'm not naive....I know it will have limited effect compared to other stuff....but worth a shot.
