Recommend by my Amazing Veterinarian! Love this product, saved my sweet horse.
MPCO ONE AC, is a Gods Send in my Opinion. My sweet horse suddenly stopped sweating my amazing Veterinarian recommended I use this product. Within 6 months my horse started sweating, sheâs back to normal sweating all on her own.I have been adding One AC to her daily feed since then. Very Very Happy with this product…

Effective for horses- non sweaters
Effective on most horses that don’t sweat. Others require more aggressive treatment.

This is the best for horses that are not able to sweat to regulate their internal temperature
My 34 year old Morgan horse has cushings and has lost the ability to sweat to control his internal temperature. One AC not only helps control his coat growth but also helps reset his internal thermostat

Worth Every Penny
I purchased a horse in Arizona summer of 2008 and he was diagnosed with anhidrosis. One AC was the product recommended to me to help remedy the problem, and I have been extremely pleased with the results. My Oldenburg/Arabian was consistently worked in extremely hot weather in the Phoenix Valley and was able to remain very competitive because of the increase in his sweating. After several years in Arizona, we have moved to northern Virginia. I have continued to use One AC and remain very pleased with the results as he continues to sweat well during the muggy summer days. Personally I do not use One AC seasonally, he stays on it all year with his Platinum Paks and receives two scoops/day. I would highly recommend this product for any horse who has issues sweating to improve the quality of their work and their life. I just ordered more recently, and I will continue ordering it for my horse until he passes.

Product made my horse sweat, as advertised
Product worked as advertised. Horse has now passed. I cannot get anyone to cancel the subscription as it apparently comes from the pet store listed. I have requested and requested and it still keeps showing up every month in my orders. Help, please!

Really seems to help
Took about a week but my older gelding who’d stopped sweating this year, started to do so on this product. Thank you! Will order every summer.

It helped
For 5 years we have been giving the non-sweating quarterhorse various treatments. From guiness to every sweat supplement to thyroid meds that the previous owner had him on — they all had limited success.We tried One AC along with Equiwinner (look it up, it’s a weird one) and now have a moderate sweater. Not sure what is working but we will keep using One AC too see how long we can keep this up. He seems to be sweating more than he ever has and not blowing while standing in the stall so we are hopeful ONE AC is the solution for him.

Our horse was not able to regulate his body temp because he has started to have dry coat, we live in tropics. This has increased his sweating response greatly. Very happy
