I recently started considering alibaba for supplements and it seems like Chinese labs produce/synthesize anything for the right buck.
Out of curiosity I checked NMN and found a few vendors selling, one biotech even for quite cheap:

There are a ton of vendors with different price ranges. Looking at this very cheap one, a month of NMN (given a intake of 250mg daily similar to NR) would be roughly $40.
Even the kg options like https://m.alibaba.co...7009.183.6fmYQX seem like a good deal for a group buy if it's really what it claims to be.
Am I missing something crucial here? I feel like I do but I am not sure what.
What is your opinion on this? Is it worth buying a small test-batch and analyzing it if it really is NMN?
