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 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

Don't bother!
This product is a big expensive joke! It does absolutely nothing. So sorry I wasted my money. You will be very sorry if you buy this product. I did not want to give it any stars but it made me to put a review in.

Did not work at all!
I took this product because I was told it would help with control of appetite. Really saw no difference, if anything I felt more hungry during the evening. I personally do not suggest it.

Returning Product
I have been able to maintain the exact same weight for months, but I wanted to loose my 10 extra pounds for an event coming up. As soon as the second day of taking this product, I notice the scale slowly going up. I kept thinking that I just needed to give it some time to see the real results. After only taking the product 2 WEEKS, I have gained 5 POUNDS! I didn't have any other changes in my diet or exercise; taking this was the only difference. So disappointed! I feel like the guy at the store only recommended this because it was one of the more expensive products on the shelf.

I weight 125. I workout 5 days a week cardio and weightlifting.I eat very healthy as well. I was wanting to shred down the % of body fat to really get my body looking good. I bought this one because I do not like to feel jittery or have headaches from weightloss supplements (I did hydroxicut WAY back in the day). The first day of taking this made me very nauseated. I also started getting small headaches throughout the day. I made sure and chugged water like I had read in reviews. Not much alleviation. I have been taking it for a week and see no changes, besides sweating more at the gym. I still get nauseated during my workouts (usually when I'm lifting and it does't take much however not so much when I do cardio) and still have headaches. There was one day when I did not take this product and I felt as if I had a massive hangover for a good portion of the day. I will say that my mood has seemed better when I have been on them (so theres a good thing). However I don't like the headaches and cutting my workouts short to sit down and wait and see if I'll puke or not. I'm returning them the week and going to try anther product.

Epilepsy and this product
I'm a nutrition/fitness buff as well as a nurse who happens to have epilepsy so when it comes to supplements for my workouts you know darn well I check double, triple 6, 10, 30 time check my facts before taking anything. Been on this product since July and started with 1 cap in the am then went to 2 cap 1 in the am and 1 at hs (bedtime) for a week then to the recommended 3 caps putting 2 in am and 1 at hs. So far no side effects and works wonders, I've taken it anywhere from 20 mins before bed to right as I am getting into bed and it has not messed with my sleep in any way shap or form nor has it caused any reactions with my medications that I have noticed. If I happen upon anything in relation to this is the future I will update this
