Thanks for all the input and I forgot that it might be against the drug
rule. Although several brands claim that is "natural" ingredients and not
against most drug rules in shows, etc. Competition aside, I'm still asking if
anyone has used this stuff when riding and does it help. I used to endurance
ride and have started several horses. I'm no longer interested in 50 mile rides
(I've done plenty). I am 15 years older and am looking for an easier way to get
them used to the excitement. These two get pretty wound when in a group and it
is not fun.
