" All of the stimulant-free pre-workouts that I’ve tried in the past never did anything for me. Unexpectedly, Mammoth Swell IQ actually blew me away. I purchased the product without getting my hopes up, but to my surprise, this product absolutely delivered. My workout performance improved, and I love the included nootropics and the way they make me feel ".

" This pre-workout is delicious. In fact, it’s quickly become the highlight of my day – it tastes THAT good. Sipping on Swell IQ on the way to the gym has turned into a “pump up anthem” during my drive. Good music, good pre, I can’t ask for much more (except for gains, we could always use more gains). ".

David M


" I’ve been using stim-based pre-workouts for years but realized my adrenals were getting fatigued. I decided to give Swell IQ a try and allow my adrenals to reset. Now that I’ve tried this pre-workout, I don’t see myself ever going back to anything else – including stimulants. My workout intensity has increased and my results prove it "

" FINALLY!  A pre-workout without being loaded with a bunch of stims! I’m sensitive to caffeine and also work out at night so anything with stimulants keeps me awake. I was worried that I wouldn’t feel much from Swell IQ but was pleasantly surprised when I experienced an increase in energy, performance, pump, and focus throughout my workouts. I’ll definitely be buying this again and in more flavours. ".
