Thanks for the update! Sorry to hear that. One bottle breaking seems to be not infrequent with A. I was researching N a few years back and that was a complaint I heard often. I know A is legit btw, I am in no way disputing this. For those thinking about A over D, his communication is pretty much always piss poor; that's something to consider.
(To go back a few years) At the time, I didn't know much about N, so had little trust in A and his shit English and slow responses made me nervous. I "tested" him, by emailing him only a few weeks apart, with three different email addresses describing a similar weight (8 stone - 8 stone 7lb) and I was given wildly different responses, which is partly why I backed out of buying.
He basically said: one bottle was more than enough, that even a tiny, tiny amount of one bottle would do it, I only needed to bother getting one. To the other email account he said, two were necessary to cause death (this was to the address w. the lowest weight of 8 stone). And finally to the third address: well, two is standard/what most people order, one might get broken, so you'd be better off buying two. (I was definitely in contact with the real A btw.)
Today, knowing A's rep, the inconsistency wouldn't bother me, it's up to me to make up my own mind; but it was bloody off-putting at the time lol.
