You could buy the mexican generic Himanix on that site which is half the price. The 20 pill pack should be more than enough for one person. They make a ton of this drug for the third world. If you hunt around you might be able to find it for under a dollar a pill however. Its a cheap drug to make. > So you are taking the 4x C D Zinc all the time even without covid? No! I should have been more clear. Im not taking anything right now because Ive been very confident since I got my ivermectin. But all those recommends are for when you have covid. If you come down with covid or you think youve been exposed then 1 or 2 weeks of high dose C, D, and zinc are appropriate and then taper down. If I just wantd to be “ready” for covid I would take 1000 to 3000 IU of Vit. D a day, around 1000 to 2000 mg of vit. C and maybe around 25mg of zinc. Much less for long term! I just like that MFL CDZ product because if you get covid, you don’t have to worry too much about a bunch of different pills, because it has the 3 important ones in roughly the right proportions. You could just take 3 or 4 a day for a week or two when sick. Otherwise you could take *one* a day long term. The vit. D is a little high for me for daily use but it wouldnt do you much harm at that dose. Matter of opinion.
