The Performix brand doesn’t show any signs that it’s going to take its foot off the gas. They’re now up to four products with the release of their new non-stimulant thermogenic Stimfree.

While certainly one of the most aesthetically pleasing brands, they’ve got a long way to go if they hope to elevate their product position from beleaguered to breakout.

Clinically Dosed

Performix is heavily invested in promoting a few patented ingredients in Stimfree which are dosed according to research. Here’s a quick overview:

• Capsimax (100 mg) capsicum fruit extract- A pepper extract which has the ability to increase thermogenesis, stimulate fat burning, and boost metabolism.

• Greenselect Phytsome green tea leaves (300 mg)- Contains catechins which boost metabolism, increase fat oxidation, and enhance thermogenesis.

• Zychrome chromium dinicocysteinate (400 mcg) – Chromium helps with weight loss by enhancing insulin function and promoting better blood sugar management.

What’s more, Stimfree also has garcinia cambogia and green coffee extract to help with appetite suppression and weight loss.

Price and Availability

Like other Performix supplements, Stimfree is exclusive to GNC. The non-member price is $79.99, and the member price is $59.99. Unfortunately, even at the member price, you’re still looking at paying $2.30 a day.

This is another scenario where the price gets the best of Performix. Stimfree might have some patented ingredients, but it’s also one of the most expensive fat burners out there.

Should You Buy Stimfree?

Unfortunately, Stimfree suffers from the same problem as the other products in its line ─ the price point is just a little too ambitious.

    I took one pill before a bicycle ride. I ended up fainting during my ride, crashing, and ending up in the hospital with broken bones. I am an experienced athlete and this has never happened to me before. It was a hot day but I was properly hydrated. I was in the hospital for 2 days of testing where they determined the my heart, nervous system, etc were all in tact and not the reason I fainted. The doctors at the hospital said that they believe this supplement caused me to lose consciousness and that nothing at GNC is FDA approved and I should never again touch such a product. In fact, they believe the pill masked how dehydrated I actually was. I felt fine on my ride and was drinking water and Gatorade the entire time. But at the hospital I was so depleted they couldn’t find a vein for my IV and had to use an ultrasound just to locate my vein. Again, I have been running and biking for many years and have even completed an Ironman. Nothing like this had ever happened in my life. Please stay away from this product.
