On September 23, 2022, the FDA issued a warning letter to Muscle Sports Products, LLC following inspection of the company’s websites which found statements about company products, including Join Revolution Capsules, IMMUNITY + Powder, Rhino Rampage PUMPED Capsules, Attack Pre-Workout Powder, THERMX Powder, and HPEX Powders to be drug claims.

For example, the company’s Joint Revolution Capsules were promoted with statements such as, “Chondroitin Sulfate – May help with relieving joint pain, stiffness, and other joint symptoms,” “Bromelain – Decreases swelling and inflammation in soft tissue and joint disorders,” and “Quercetin …possesses anti-inflammatory…properties.”

(See ConsumerLab’s Joint Health Supplements Review for more information and tests of related products.)

IMMUNITY + Powder, which includes vitamin C, vitamin D, zinc, L-lysine, echinacea, elderberry, and more, was promoted to reduce upper respiratory tract infections, common cold and flu symptoms, and herpes flare ups, among other things.

(See ConsumerLab’s Reviews of Vitamin C Supplements, Vitamin D Supplements and Elderberry Supplements.)

Rhino Rampage PUMPED Capsules which contain niacin were promoted to, “increase high-density lipoprotein (HDL), or the ‘good,’ cholesterol. HDL cholesterol helps sweep up low-density lipoprotein (LDL), or the ’bad,’ cholesterol, in your bloodstream.”

(See ConsumerLab’s B Vitamins Review for more information and tests of related products.)

Ingredients such as chromium and others in the company’s Attack Pre-Workout Powder, THERMX and HYPEX Powders were promoted with statements such as “Chromium is an essential mineral with a role in insulin regulation and glucose management. It affects chromodulin, which improves its ability to enhance insulin receptor activity.”

(See ConsumerLab’s Reviews of Chromium Supplements and Muscle and Workout Supplements for tests of related products.)

In addition, these products were found to be misbranded because the labels failed to provide adequate directions for use.

The company must respond to the FDA within 15 days outlining the steps taken to address any violations.
