On the website of one of the (one reputable) suppliers of Thai NDT, the following info can be found:
"Due to the African Swine Fever epidemic, production of Thiroyd and T.R. have been discontinued until further notice. When our existing inventory is gone, it's gone."
If this were true, why only Thiroyd and T.R., and not Thyroid-S...I doubt this is true as I know T.R. has been discontinued and rumour has it Thiroyd has been, too, but I am worried about sellers who post this kind of info...this makes it sound like it was somehow unsafe to take Thai NDT, which is far from the truth...
