I had to think about that a bit. I have used it for a short while some years ago, but I simply got sort of bored adding it, since I didn't notice any spectacular results.
Now around that time at the GNYOS ( at Rockefeller Center then) I overheard one of the Vendors discuss with a customer potting up a whole lot of Orchids which were pre -ordered and came bare root. I remember him mentioning that it wasn't too expensive to soak them in water with Super Thrive added to pot up just a couple of Orchids, but - dealing with a whole lot of plants getting faster over the ordeal of traveling/transplant shock, he said he soaked them in water with a little sugar added. It was a lot cheaper than ST. Now I don't remember how much Sugar he used, but I thought that was interesting.
