Does anyone have any experience buying nicotinamide riboside from sources on Alibaba?
While you've got to buy in bulk, it seems you can get NR for 1/10 the price per gram if you were to purchase it by the kilo ($680 usd). Some digging on the suppliers (Chinese) would seem to indicate they're legitimate.
I'm guessing with all the knowledgable members buying Niagen from HPN at 10x the cost, I'm certainly not the first to consider this.
