Best intra workout I’ve used

I’ve tried a few over the years and never noticed much of a difference but with this one, there was a noticeable difference. I hit +2 on almost every lift. This is a new staple in my supplement stack!

Elite Product

Absolutely elite product. I like to sip half before my workout and finish the other half during my workout. It gives absolutely nasty pumps and helps me crush my lifts. 10/10 would recommend.

The Search Stops Here For An Intraworkout Blend

The supplement market is an overwhelming landscape to navigate - mostly full of junk. For more than a decade & a half, I've tried more than 15 different intraworkout products: Spartan Fuel finally delivers what I need without any jitters, crashes, or negative side effects.

The most recent experience I had with Spartan Fuel paints a good picture of the superior product quality. When I used for a lower resistance training session, I could tell my body was getting more of the fuel it needed to support some of the final sets of compound exercises like hack squats & squat presses - particularly at the end of my session. Anyone focused on hypertrophy will know that delivering those essential amino acids late in a workout can be tough, but pays invaluable dividends for both muscle growth & post-workout recovery. Spartan Fuel did precisely this unlike many others.

An additional factor I take seriously in an intraworkout product: hydration capability. As I get older, I've started to truly understand the importance of hydration for performing & injury-proofing. When I'm not properly hydrated, I often feel fatigued & crash at the tail end of longer sessions. The electrolytes blend kept me dialed in with proper nervous system support & energized for a 75-min leg session without the experience of any crash I've experienced in the past around 45 min mark.

As far as the flavor, the balanced natural sweetness of Spartan Fuel pineapple is not overpowering & exactly what many other intraworkout products I've tried in the past had been missing. It possesses a subtle tartness & delivers an authentic tropical taste.

Spartan Fuel not only checks the boxes of a good intraworkout product - it dominates the market! A no brainer I'll be coming back!

Tastes great, does it's job.

Spartan fuel first off tastes great. No one wants to suffer with a bad sports drink. But most importantly it really fuels my workouts. I ever fade or feel I'm lacking the fuel to lift the weights. Heavy lift days 2 scoops, mobility days one scoop. Great stuff.

4.5 stars. Very good intra workout

Very good intra workout. I would give 4.5 stars if it would let me. I have been using an intra for a while now. I normally mix 3/4 scoop gorilla mind intra, 3/4 scoop karbolyn fuel, and a scoop of whatever brand EAAs I happen to have at the time in water. It works great and tastes amazing. Spartan fuel is all these ingredients in 2 scoops. The formula is top notch. My only knock is the flavor, which I understand they’re already working on, so I have very little to critique. If the flavor improves just slightly and the price comes down just a few bucks per tub, I would easily give this 5 stars. Anytime this is on sale, it’s worth picking up.
