Does this come with a pump?

Answer by Chewy • Oct 30, 2023
This supplement does not include a pump.

Is there a pump available at chewy for the gallon size as pictured?

Answer by Chewy • Aug 17, 2025
At this time, pumps are not available at Chewy.

Will this make my horse hot?

Answer by Chewy • Feb 29, 2024
This supplement will not change your horse’s temperament or make your horse ‘hot’.

Does the horse need to stay on this for life or can you cut it out once the desired level of muscle is built?

Answer by Chewy • Jul 13, 2022
You can keep the horse on Performance Builder until you have achieved the desired level of muscularity, then you can quit.

Picky eater approved!

My older warmblood is doing great on this, but she’s on a few other supplements too and has her hocks done so it’s too soon to tell how much this liquid supplement

My older warmblood is doing great on this, but she’s on a few other supplements too and has her hocks done so it’s too soon to tell how much this liquid supplement actually contributed. I kind of threw the kitchen sink at her and will start to remove things one by one to see what actually worked.

Item came damaged and two other items were also damaged -

this product was damaged split wide open the bag it was in split wide open. There were two other items in the box. They also split open one was a powder substance

this product was damaged split wide open the bag it was in split wide open. There were two other items in the box. They also split open one was a powder substance. The other was a horse food, and the liquid went all in them ruining it. What was worse? I called customer service 20 minutes after explaining the line was disconnected. Nobody called me back. I had to call back. Go back through the explanation again, and the guy was almost reluctant to issue a refund or redo the products. I’m finally getting my products but not all of them and it was very frustrating with the customer service. This is the first time I’ve encountered this with chewy, but it was a large order that was damaged

This Really Works

Purchased this for an elderly gelding of mine. He was injured in June and while recovering lost a good deal of weight/muscle. This was instrumental in his recovery

Purchased this for an elderly gelding of mine. He was injured in June and while recovering lost a good deal of weight/muscle. This was instrumental in his recovery. Would definitely recommend!

Makes my mare salivate

It smells great! It's an easy bottle to store but it makes my mare salivate and she will refuse to eat it now. She's a OTTB who i s pretty good at eating things

It smells great! It's an easy bottle to store but it makes my mare salivate and she will refuse to eat it now. She's a OTTB who i s pretty good at eating things. Maybe she's allergic to it? We keep it inside so it's not rotten or anything. It just makes her super slobbery and she shakes her head :-/

This muscle builder has been a game changer for my horse! I’ve noticed a significant improvement in her hindquarters and topline. She is visibly more muscular! The best part is that she seems to have more stamina during trail rides ( under 8 miles maybe once a week) , and her overall outlook on life is better. Ellie has to be feeling better! I wish I would have documented with a close-up picture of her cheeks, take my word they are filling out. Ellie is around 20 years young !

This is a very effective supplement

This supplement delivers results so I purchased the bigger size to save a little money. This size needs to come with a pump or a pump option.

Perfect Top line Supplement

Really works well for all my horses but especially my OTTB - Sully you will definitely see results within 2 Weeks especially if you are long trotting and riding

Really works well for all my horses but especially my OTTB - Sully you will definitely see results within 2 Weeks especially if you are long trotting and riding them to help build their muscle. Results in 3-4 Weeks if they are laid off and you’re not working them daily and trying to help them put on weight. Really wish I took a before and after photo! I will be buying this product again - Just in the gallon jug this time!!
