Product Overview



FinaFlex Stimul8 Bottles



FINAFLEX STIMUL8 is an Ultimate Super Pre-Workout built for both men and women that STIMULATES your workout like never before! The tested and true STIMUL8 formula is powered by ingredients designed to provide you with the energy, strength, and endurance needed to take your workouts to the next level!*


STIMUL8 features a combination of ingredients that can only be found in FINAFLEX formulas, called IRISINXD. The ingredients contained in IRISINXD have been shown in research to benefit and support body healthy composition, or the ability to build muscle while burning fat!* Combining IRISINXD with other shredding and muscle building ingredients creates the ultimate preworkout formula!*


You read it right...start with 1/2 a serving! The STIMUL8 formula is SO STRONG that most users need to start with a 1/2 serving (1/2 scoop) to determine tolerance. Make no mistake, STIMUL8 is not a 2, 3, or 4 scoop product! Due to the extreme effects formula, most men & women find that 1/2 serving is just right! When in doubt start with a 1/2 serving of STIMUL8 to assess tolerance, do not exceed recommended dosage.

I got this as a sample in my GNC Pro Box and fell in love. Got on your site and ordered it that same night! This pre workout works amazing! Talk about mind to muscle connection during a workout. Now my hubby uses it too!

All around best preworkout in the market! Tropical storm flavor is by far best tasting p/w I've ever had! Laser shop focus, gives me all the energy I need, and then some more!

I’m a lover of the tingly stimulating feelings from pre. So i tried this one because i knew it was a high stim. I definitely wasn’t expecting the kick i got from this because i ignored the half scoop warning. Listen to the label and do a half scoop. Lol i took a full scoop and it was like getting two pieced by mike Tyson. It hits you in all the right ways, and wrong ways if you do what i did. It serves its purpose as a crazy stim pre.

Been on and off pre workouts since 2011 and this is one of the best out there. You'll never need more than one scoop. I could easily take half a scoop and still get through my workout on this stuff. Highly recommended.

Stimul8 is hands down the best pre-workout I've ever tried. Incredible pump and focus throughout the whole workout. I've had the best workouts when I take a scoop of my Watermelon Stimul8. Whenever I'm feeling low on energy, I know I can always rely on Stimul8.

I tried the Blue Stimul 8 preworkout from a sample pack and was blown away! This is easily the best preworkout I have ever used and it tasted great too! I used two-thirds of a serving initially, and felt the extra energy quickly and sustainably. I cannot wait to try the rest of this product's flavors.

The product is very effective, and very strong. do recommend using half a scoop first before taking the full scoop.

FINAFLEX STIMUL8 is a good cutting pre-workout that doesn't give you jitters. I recommend to try it if you are looking for intensity without the jitters. The Biue Raspberry is my favorite, but Bodybuilding does not seem to sell it as of right now.

I have tried many different preworkouts for the last couple of years and none compare to Stimul8! I thought I had built up a tolerance for them because none would hit me as hard anymore. But then I tried this one and it exceeded my expectations. I get a great pump and it hits me in like 15 minutes. I am definitely buying this one again

THIS PRODUCT WAS AMAZING!! So much better than other products I currently use. The APPLE BLAST is definitely my favorite. The balance in the ingredients they use gives you a awesome clean burst of energy and power! Definitely recommend to anyone looking to try something new.

The first week I only took a half of a spoonful and it was plenty. I now will only use this product. I used to use C4. I am not a gym junkie but I love going to the gym 3-4 times a week.
