My horse needs an energy boost for her run. What can you suggest? Training is not an issue. I am looking for a pre-race paste to give her to help with energy. Thank you!

What type of diet do you have her on, could be lacking something. 

Diet is good. Horse is N/P4 and well managed. Muscles are jello soft. Alfalfa hay, Timothy hay 24/7, filtered water, Nutrena Top line Balancer, Triple Crown Senior, Excel, Lubrigen, Remission, Vit. E, Vit C, Salt, Triple Crown Flax,  Alfalfa Cubes, 25,000 MSM, Mare Magic. All is good on the diet front. I am just looking for suggestions to help on race day for an extra boost. Kinda like a Starbucks Coffee to get you going. 

Are you really feeding your horse all those things? What is the purpose of alfalfa cubes if your already feeding alfalfa? Why the ration balancer along with the complete TC senior feed? It's my opinion that all the stuff the horse is getting might be toxic and thus, no energy. 

Whats the purpose of all these different supplements? In my opinion your feeding to much supplements, why the remission and mare magic? I would just feed the Triple Crown Senior and stop all the extras that you are feeding I would not be adding anymore to this mares diet. I bet if you just stick to feeding a good diet (just the Triple Crown) your mare would feel alot better. Mucles should be a bit firm not jello soft.. 

OE Nitro will deliver that quick energy kick that you are looking for.  I have only used it on a couple of solid, very calm minded horses, but it has worked excellent for them.

I agree with others on supps. Maybe talk with a nutritionist to make sure you're not over supplying some things. 

To answer what you actually asked, Oxy-Gen RUSH and MVP Breath 02 will both give you a good amount of umph. Like fire breathing dragon. 

I agree with all of these and will add - what works for one horse may not work for the next one. Good Luck
