Muscle Valley Performance Products, the sports division of NutraSource Products,  started in Kansas City in 1997, the year we introduced the first bona fide GH releasing formula to the bodybuilding world. In 1998 we were the first company in the western hemisphere to put Siberian ginseng and Siberian golden root into a dietary supplement. That product was GH-Elite. Both were from Russia at that time.

In 2001 we developed Performance Gold, a powerful, all-natural performance enhancing formula. Performance Gold was the first supplement to contain the fenugreek extract Fenutest, which is a powerful strength and muscle-building plant-based ingredient equal in effectiveness to tribulus terrestris.

All ingredients are tested for purity and potency. Only the highest quality raw materials are used. That's why we have been able to keep the same customers for 10 or more years, because the higher the quality, the better the results.

Muscle Valley products have been sold through doctors and health professionals, trainers and directly to the end user. We have also sold our products into Europe and Asia mainly distributed to elite athletes.

In 2015 we moved from KC to the Missouri lake region town of Warsaw.

We will never cut corners because that lets our customers down. And, besides, we're users too. We're not a big company but we are an honest company. If it's listed on the label, it's in the product. We stand behind our products 100%.

NutraSource Products is the parent company of Muscle Valley Performance Products 

Developing innovative and effective products since 1997
