My horse has been totally off the Platinum Refresh for a few weeks, but I did purchase some Let M Sweat, which has similar ingredients and a 1 oz/day serving size (half of the Refresh). A 5# tub is an 80 day supply, so it’s also much more economical (although the shipping cost was quite high).
For comparison, a 30 day supply of the Refresh was $115 (including shipping), while160 days of LMS was $148 (including shipping). Shipping the LMS was expensive enough that I decided to purchase a second tub, as that added only a few dollars more shipping cost; can always use it next year.
I’ll spend the money if something works but, while Refresh did seem effective, my not particularly picky eater wasn’t enthused about an extra 2 oz daily of an apparently yucky powdered supplement, considering that his meals are too small to hide it (even when fed at 1oz per meal twice daily). Refresh is too costly to waste. He has no problem eating the ounce of LMS in a single serving and the best part is that a few weeks in, he’s sweating better than ever (and without getting any Guinness). Think I’ve found a winner.
