Where to Buy

Vitamin Research Products is no longer selling BHT. They are under new management and have discontinued several products, and switched other product's formulations without notice. If you are reacting to an encapsulated BHT product, try buying BHT in bulk. It's cheaper, and if you dislike the taste, you can put it into capsules knowing that there are no excipients, fillers, anti-caking agents or flow facilitators.
Where to Buy

Yes. I have received reports from people for BHT efficacy for both hepatitis B and hepatitis C. Hepatitis A and E are reported to be non-lipid-enveloped viruses.
I have not ever had any reports about HepD or HepE, but HepD is a lipid-enveloped virus.
Where to Buy

BHT is not generally hard to buy. It is a relatively cheap chemical and can be purchased for non-medical reasons, like, for example, making candles from fat. But there are a couple of things to know.
First, BHT comes in different purities. The technical grades are intended for use as preservatives in gasoline, oils and biofuels. They can be 96-98% pure, which translates as 2-4% impurity. You do not want this grade of BHT.
What you want is food-grade BHT. Or better. The certificate of analysis will show a purity above 99%. So if the vendor does not state FCC (food chemical codex) or equivalent certification, either look at the purity numbers or don't buy it there.
In some countries, Customs agents have an agenda to prevent their citizens from accessing nutrients, pharmaceuticals and cures of which they disapprove. If you have a shipment of BHT that is seized and you cannot negotiate its release, consider a stealth approach. Order the BHT and have it shipped to a friend where it is OK, then have your friend repackage it in a birthday card, or a T-shirt, or a paperback book. Powder can be transferred from a bottle (bulky and conspicuous) into a plastic bag (or nested plastic bags with a layer of clean paper between to minimize sound and the possibility of a puncture). Capsules can be placed in a plastic bag, adjusted into a single layer, and the sir squeezed out to make a one-capsule-thick slab, which will fit in a Christmas card.
Your friend in another country can they send it to you as correspondence, or as a gift.
If you are going to dissolve the BHT in oil after you get it, for ingestion or for topical use, the BHT can be easily melted in a double boiler on a stove and cast in a mold as a bird, donut, candle, paper weight or other "innoccuous" or artistic shape.
Where there's a will, there's a way.
Good luck.
