Thank God for STIM-FREE

I have really high anxiety and was looking for a stimulant free pre-workout since I just started my weight loss journey. Tried this product and felt very very mild side effects (face itches for about 5 minutes after I take it).

My boyfriend started taking it too and he loves that he doesn’t feel over-energized after our workouts since we do evening workouts. I love this stuff and am so happy I found a product that doesn’t freak my body out but makes me push harder. Thanks Transparent Labs!

Katy B. writes:


Within 2 weeks of starting the stimulant free version of the supplement I was able to quit drinking coffee. Each dose provided me with energy that lasted throughout the day with no jitters or anxiety.

Within 3 months of use I lost 10 lbs and have been able to maintain the weight and energy levels. I LOVE THIS PRODUCT!!! THANK YOU TRANSPARENT LABS!!!

Adam V. says:

Great Stim Free Product

I use the stim-free pre-workout and the stim-free fat burner as I find the caffeine really makes my heart race (bad since I have High BP). These products are awesome.

This is the first time I’ve ever used a fat burner. I’ve been on it now for 2 weeks and I can already notice a difference getting rid of that last bit of stubborn fat. Be warned though…it MIGHT make you run to the bathroom a bit more urgently than you usually does like it does to me…just make sure you get your water in 🙂 Definitely recommended.

Jacob R; says:

Product works

Not much to say here. The ordering/shipping process is straightforward and easy and the products works as advertised.

I’m a repeat purchaser of the pre-workout supplement and have found it to be very helpful as I workout early in the morning before work and it allows me the opportunity to have a great workout session every time.

Henry R. writes:

Stim-Free products are amazing

I just picked up the Stim-Free preworkout because I hate the jitters that I get with other supplements. This stuff totally works and I feel that it’s more effective than everything I have ever tried. During and after workout you get this surge of energy that just feels natural which is very unique to this product.

Being a skeptic, I tested out its performance to see how it compares to the other preworkouts that contain stimulants and so can honestly say that I was able to push harder, run faster and longer with the Transparent Labs product. Definitely will buy some more and definitely worth the price for a high quality product. Love it. Read Less

Workout energy without anxiety

I first learned about Transparent Labs Stim-Free products from a workout buddy, and this works perfectly for me. I can’t handle the ingredients usually found in other pre-workout and fat burner products, which would make my heart rates or cause anxiety. I’ve already noticed some leaning out and a couple pounds lost. I also really like their pre-workout for the same reason. Energy without anxiety.

Austin N. writes:

I bought this product to help with food cravings as I changed my diet to loose a few pounds of fat hanging around my mid-section. So far after 2 weeks of using Fat Burner Stim-Free with diet change and exercise I have lost 8 pounds.

I like the fact that the Stim-Free doesn’t upset my stomach or give me headache. Very good at reducing food cravings after eating also.
