I have yet to get my worthless TSC to order me Tech Master. If anyone knows of a store carrying some within a 100 miles of 77357 please let me know. I did find this place that says they will make a custom mineral for you, so I have sent them an email to see if they will make a mix like Tech Master. If they say yes I will report back. They have this stuff currently. http://www.swlm.com/warner.htm Funny if you read the bottom they say not to give to sheep and goats because of the copper. Funny how little people know about goats.
