I’m 56 and I’ve been lifting for 30+ years. I’ve tried hundreds of products. Most of them don’t do **** and taste like garbage. This stack is awesome! Gives me a ton of energy, even for an old guy like myself. But the best part is it tastes really great. Don’t have to choke it down. Worth the money.
Delicious. Good price. Great quality. Actually works. What more do you want? I’ll be buying all three again.
The tri-protein is delicious and keeps me from snacking all day long. I’ve lost 20 lbs and I’m down 2 pant sizes so far. Great stack for the price.
This costs more than normal formulas out there but if you look at the ingredients, you can see why. I prefer to pay top dollar for high-quality ingredients that I know will work. The protein doesn’t give me gas and actually fills me up. The pre-workout gives me focused energy instead of that cracked-out energy other pre-workouts give me... and the creatine formula is super effective. I don’t feel NEARLY as sore the next day. This was a great investment.
The pre-train and CRN-5 are terrific. Delicious flavors and delivers awesome focus and recovery. I think the Tri-Protein is OK. Not a fan of the flavor but I’m a bit picky. I mix it up with a banana and some peanut butter and it makes it better. Best part is it doesn’t give me gas. Can’t wait for their other flavors of protein!
