GNC Pro Performance Hybrid Test Complex Review

GNC Pro Perfromance Hybrid Test Complex

A product from General Nutrition Center, Pro Performance Hybrid Test Complex is a dietary supplement said to be a powerful formula to support testosterone levels.

GNC claims this product triggers anabolic factors and promotes peak performance with just two ingredients. [1]

Additionally, GNC claims its products are “on the cutting-edge of nutritional science.” [2]

This sounds good, but I wonder if these claims are clinically proven.

Who Is GNC?

GNC stands for General Nutrition Centers. Lackzoom, now known as GNC, was started around 78 years ago by David Shakarian. It specialized in yogurt and also carried additional health-food products. As interest grew in natural foods, David Shakarian expanded into other states and eventually changed the company’s name to General Nutrition Centers (GNC). Headquarters are located in Pittsburgh, Pennsylvania. [3]

How is GNC’s Customer Service?

The Better Business Bureau awarded GNC an A+ rating for a low complaint volume and fast complaint resolution.

However, a couple users on ResellerRatings.com complain GNC often lists items as “in-stock” but then cancels items later that day without informing customers immediately.

“Horrible. Delayed (but understandable due to snow storms in the East Coast), then canceled WITHOUT sending an email to me. I had to check on their website on the status,” says one customer. [4]

But, these occurrences are rare. For the most part, GNC provides reliable service and speedy shipping.

And one satisfied customer says, “Price was appropriate after applying coupons. Prompt shipment.” [4]

How Do Returns Work?
In an effort to satisfy customers, GNC offers a “30 Day Money-Back Guarantee.”

In regard to this, GNC states:

“We want you to be fully satisfied with every item that you purchase from www.gnc.com. If you are not satisfied with an item that you purchased, you may return the item within 30 days from the order date for a full refund of the purchase price, minus the shipping, handling, gift wrap, or other charges.” [5]

This is reassuring, as few manufacturers provide guarantees on their products. There is one restriction though: “products need to be returned unused or used, in good condition, in original boxes (wherever possible).”

Knowing GNC provides decent quality service and a money-back guarantee is comforting. But, this doesn’t mean Pro Performance Hybrid Test Complex Plus is as great as advertised. To find this out, I looked closer at the ingredients and clinical tests.

Ingredients and Clinical Research

There is much debate about the main ingredients’ effectiveness. These debates are not brand specific, but rather are about the ingredients’ effectiveness.

Tribulus Terrestris Fruit Extract. Tribulus terrestris is used in connection with circulatory and heart conditions, and even sexual issues. There are studies suggesting tribulus terrestris provides some benefit to infertility, though how much benefit is questionable. [6]

Whether tribulus terrestris affects testosterone and hormonal levels in regard to weightlifting and resistance training is still debated. [7]

Testofen Fenugreek Seed Extract. Testofen fenugreek is used by some men to treat erectile dysfunction and other sexual issues. [8]

Like tribulus, Testofen fenugreek is still under debate. The beneficial results claiming Testofen fenugreek enhances free testosterone levels [9] are inconsistent with clinical data, as some other studies conclude it does not enhance hormonal status. [10]

Cellulose. Cellulose is a polysaccharide polymer. A food additive, cellulose is said to aid in digestion due to its inability to be digested and broken down by enzymes. [11]

Gelatin. Gelatin is said to treat arthritis and osteoarthritis because it contains collagen and eases joint pain. [12]

Dicalcium Phosphate. Primarily, dicalcium phosphate is a food additive and thickener. Some people take dicalcium phosphate to increase calcium intake and prevent osteoporosis. [13]

GNC Pro Performance Hybrid Test Complex Usage

The instruction label says to take 3 capsules a day, and there are 90 capsules in one bottle. GNC also recommends Pro Performance Hybrid Test Complex be stacked with other GNC products such as Vitapak, and Beyond Raw. [1]

Are There Side Effects?

Little is known about GNC Pro Performance Hybrid Test Complex, but there are potential side effects associated with tribulus terrestris and Tesofen fenugreek. [14]

• Nausea
• Diarrhea
• Trouble sleeping
• Bloating
• May imitate estrogen effects

Do not take GNC Pro Performance Hybrid Test Complex if you are pregnant or nursing.

Availability and Purchasing

GNC.com, Drugstore.com, and Amazon.com all sell Pro Performance Hybrid Test Complex, though when searched with Amazon.com, it redirects you to Drugstore.com.

This product retails for $26.99

Should You Take GNC Pro Performance Hybrid Test Complex?

This decision is entirely up to the user. Keep in mind the lack of clinical studies as well as the inconsistent data supporting raises in hormonal levels when considering Pro Performance Hybrid Test Complex. Though, the active ingredients have the potential for beneficial side effects, more user reviews and clinical studies are needed to confirm its effectiveness.
