I’ve used sustain for 3 years now , I wouldn’t dare to use any other supplement for my long runs and ultra runs 🤩🏃🏽♂️Best supplement for endurance athletes.
I ran Worlds Toughest Mudder last weekend and drank two scoops of sustain elite each lap. For 24 hours I drank 2 gallons total of sustain elite and I can report ZERO issues! No cramps no GI gut bombs! Absolutely phenomenal product! Will continue to use often.
I use sustain for various workouts. I'm not an endurance athlete by any means but I still find benefit. I dont eat before I workout ever. if I do a largree studio workout and cycle class back to back I need a little muscle feed and this stuff works.
Haven't had a chance to race with Sustain yet, but it's been great on my hard training runs so far. Only liquid calorie mix that I have been able to use (have tried Maurten, SIS, Gu and others) that does not cause any GI distress whatsoever, even during very hard efforts. Excited to race with Sustain in my bottle in a few weeks.
Keeps me at the level I need when putting in the effort.
