What athletes are saying
Of the proteins, I use Whey and Rego recovery drinks and recovery is noticeably faster and workouts much better. Creatine does not stiffen or create cramps like all other creatines I’ve tried so far. All SiS caffeine products are super-good because they don’t make you nauseous like all other similar products from other brands. Especially great during competitions where sharpness is needed instead of shaking hands 🙂
Three times Estonian champion in heptathlon. European Combined Events Team Championships Super League gold medal.
The main reason for using SiS products is their ability to help an athlete prepare for the competition as well to recover after. Also with SiS, I can be sure all products are free of illegal substances. My favorite is the Caffeine Shot. My competitions are usually in the evenings so staying sharp and full of energy is hard.
Estonian champion in horse riding in 2019a.
I have been using SiS products for a while now. All the products taste good and help me get better and better results. The biggest bonus with SiS is the variety of products.
Estonian records in 200m and 400m freestyle swimming in 2019a.
I have been using SiS products for four seasons now. REGO range for recovery, GO for energy and vitamins as well. During the partnership with SiS, I have managed to avoid the flu and injuries, and have set new personal and Estonian records!
50 times Estonian champion in canoeing as of 2019.
“I have been using SiS products for 9+ years on training and various competitions. Nutrition has never been an issue. I have my own favorites I can always count on. Go Electrolyte, Isotonic Gel, Go Caffeine Gel and Rego+.
Estonian all-time best triathlete. IRONMAN personal record 8:04:08.
“New products accompany the whole range very well. My favorites are Performance Greens, BCAA and SiS Magnesium which is very important to athletes. And the peanut butter flavored WHEY gel is a treat 🙂
