Safe-Guard makes a medicated dewormer salt block, and Bovatec makes a medicated block made to increase average daily gain of pasture stocker, slaughter, feeder cattle and beef/dairy replacement heifers.
However, no other manufacturer makes any type of medicated salt block that contains the mythical ephedrine that is claimed to be extracted and used for crystal meth.
They are not and never have been. Ephedrine is not found in medicated salt blocks.
There are no salt or mineral nor medicated mineral blocks that contain any form of ephedrine in them. Sick animals are treated by antibiotics via injection, not by just giving them a "medicated" salt block.
Nowhere. These type of blocks do not exist.
Blocks by Bovatec and Safe-Guard are a dark smoky-brownish colour.
None. There is no such thing as a medicated salt block, especially one that contains ephedrine that you can use to make crystal meth!!
Bovatec blocks can sell between $20.00 to $30.00 each. Safe-Guard blocks are around $40.00 each.
Safe-Guard makes dewormer salt licks to combat various parasites that infect cattle. Bovatec makes salt licks with lasalocid sodium for the purpose of helping increase the rate of gain for pasture stocker/slaughter/feeder/replacement cattle. These two brands are the only known "medicated" salt blocks that is made for livestock; all other salt blocks are not medicated and are primarily of trace mineral, iodine, cobalt and iodine or iron, cobalt and iodine. None of these other blocks are termed "medicated." Also, there is no known company that makes salt blocks with ephedrine or any other drug other than the dewormer medicine made by Safe-Guard and increase ADG by Bovatec.

Bovatec or Safe-Guard medicated blocks should be placed out in the pasture to encourage more grazing in that pasture and less traffic at the water trough. Most people like to put out salt blocks close to a water source, but in a pasture environment, to encourage livestock to graze a certain area that is some distance from their favorite watering area, a salt block should be placed in that vicinity.
NaCl. That's it: just plain table salt. And there really is no such thing as a "medicated" salt block.
You can purchase a medicated salt block at your local farm and ranch supply store. Tack and feed stores will also sell them.
Ephedrine-medicated salt blocks are regulated substances in many countries and not typically available for purchase by the general public. They are usually used in veterinary medicine and are typically available through licensed veterinarians or suppliers. It's important to consult with a veterinarian or local regulatory authority for guidance on obtaining these products.
Livestock salt blocks do not contain ephedrine. Ephedrine is a stimulant drug that is not suitable for use in livestock due to potential health risks and regulatory restrictions. It is important to follow appropriate guidelines and regulations for livestock nutrition and health.
