The explanation I got was that some degradation is expected due to transit, storage, etc and to assume instead of 10,000iu, you’re getting closer to 7-8k and to adjust your dosing accordingly.
I take issue with that because 1) if I’m paying you for 10,000iu, that’s what I expect to receive and as 808 proved, it’s possible to get that result, and 2) if you have testing that proves your product is bunk and you’re withholding it so it doesn’t affect your bottom line, I no longer trust you as a vendor and you should either A) remove the product from your inventory, or B) refund customers who purchased it.
I tossed mine personally because I no longer trust that vendor.
