To best of my knowledge, these are facts-about-IPF-immune:
ENZC announced IPF production and sale in north America in November 2021.
ENZC confirmed IPF was coming in March to multiple online retailers, and described an extensive marketing campaign.
No one could buy it in March.
Then we were told that we could buy it in April.
No one could buy it in April.
To date, it appears no one has been able to buy it at all.
We finally learned why the launch didn't happen months later in August, when the company said the demand was too high for their production capacity.
And even later, according to the (very late) September filing for Q2, there was zero income or revenue from IPF - so it appears they never even sold one bottle.
Chandra had tweeted a photo of what was supposed to be the first shipment of IPF to North America (see photo at end of this post). The tweet is since deleted. There should have been 42 bottles there and at $39.99/pop (debut price on OneLavi) we should have seen ENZC report about $1680 in revenue sans any cuts from retail partners. To date, we don't know what happened to those bottles.
OneLavi (the only retailer we know which temporarily attempted to sell IPF Immune) no longer has a listing on their store page, even with a Sold Out label.
