"This is a very interesting area..."
"My wife set up a blind study for me because I got my hand on some CILTEP… We did a blind test… Out of these 20 trials that I did in these 10 days, my four fastest ones were all on CILTEP."
"I've relied on CILTEP as my go-to product to optimize mental performance for the seven week long WSOP."
"It definitely helped me get through the long days and stay focused all the way through. I've noticed a remarkable difference in my ability to spend hours at a table without a break in concentration. This product really works."
"I am seriously impressed with CILTEP"
"CILTEP has earned a place alongside world-class smart drugs. It works synergistically with them to help you do - and be - more."
Natural Stacks formulas contain premium ingredients which are carefully selected solely on the basis of quality and purity. We actively seek out the most bioavailable forms of each ingredient, and avoid the cheap synthetic forms used by the majority of supplement companies.Learn More
Most companies use "proprietary blends" so they don't have to tell you the amount of each ingredient in their formulas. It's a shady and sometimes dangerous practice. At Natural Stacks we believe it's your right to know exactly what you're putting into your body. We proudly publish our innovative formulas in an open source format.Learn More
