Product Information



PERFORMIX™ STIMFREE is a revolutionary weight loss activator with clinically proven key ingredients.* This advanced ingredient formulation includes three patented ingredients — Capsimax®, GreenSelect® Phytosome® and Zychrome® — all in dosages shown to be effective in preliminary clinical research.*

Using TERRA Intelligent Dosing™ technology, an innovative Multi-Coating Matrix (MCM), combined with a pH-phased, delayed release functionality, PERFORMIX™ STIMFREE delivers premium ingredients via multiple targeted release points to help offer a sustained release profile along with improved delivery.

POWERED BY: CX2™ Thermogenic Activator* contains award-winning apsimax®, which induces thermogenesis with the hot natural capsicum fruit extract from red hot peppers without the burn. With the clinical dosage of 100 mg daily, studies have shown that the capsaicinoids in Capsimax® help support healthy metabolism, manage appetite and support fat breakdown.

GreenSelect® Phytosome® is a caffeine-free proprietary extract of green tea leaves. The clinical dosage of 300 mg daily has been shown in studies to support weight loss (an average of 30.86 lbs in 90 days versus 11 lbs in the diet-only group).*

Zychrome® is chromium in the form of chromium dinicocysteinate that has been shown in studies to be twice as effective as chromium picolinate in supporting insulin function. Zychrome® is provided in the clinical dosage of 400 mcg chromium dinicocysteinate daily.*

I like the stem free, so far. Have not lost weight yet but I noticed I don't seem to be as bloated as i was and that is nice. Hopefuly I can continue with stem free for a while longer & see if I can lose some weight.

Curbs Appetite
After three weeks of usage, this product definitely curbs the appetite but I cannot attest to any significant weight loss. I will continue using the product until the end of 2017 to provide a more precise review.

I have not noticed any weight loss with this product.
I have been taking this product for over a week and so far I have not feel that it has done anything to me. I am planing to continue using it to the end and see what happened, but so far this product has not been doing anything for me
