Hi Beth,
Yes, I agree, so even if a protocol was found for horses, creatine would 
be of probably no use at all to endurance horses, who obviously exercise 
for alot longer than a minute or so.  Actually, I was sortof thinking 
more of the sprint horses, ie quarterhorses and maybe TBs who do go 
anaerobic semi-instantly and would depend alot (or at least would be 
helped by) the CP system.  Sorry, I get off on tangents (pretty much 
anything is grist for my mill some days since I got that espresso 
machine ;-> ), so creatine discussions really don't have anything to do 
with endurance horses.  Was just surprised to see that no one has seen 
an improvement in sprint horses.  I'd still love to see some muscle 
biopsy results, though.
