Peter
to say to you
i cannot answer your question fully really as i never use them, ( i have tried in the past ) and they do not agree with me
i only drink water, diluted squash, and occasionally glucose powder
but i stand by what i said earlier
what ever experimenting you do- get it done with 14 - 21 days to settle your system, as if something doesnt suit you, all the prep could be for nothing
i would also advise, with all the excitement of the day - if anyone says, here try this, to be polite say ok thanks
i do wish you luck and a happy run
But do NOT consume it
