Review: The Only Supplement Company with Integrity (Tested) - NootropicsDepot is provably the best supplement company in the industry... Want proof? Ask other companies for their COA's and advanced testing. Only one company has the integrity to publish all of their results - that's Nootropicsdepot (ND). If it's not ND, it's an inferior product. I will only take ND supplements because I have seen the LACK of testing that goes into other brands, (which I won't name here, but unfortunately includes almost every other supplement company in the market). If you care about your health, your families health, the integrity of a company and the purity of its product, NootropicsDepot is the only choice. As for this particular product, I noticed an almost immediate positive result within 45 minutes after taking it on an empty stomach. I noticed greater clarity and recall, which has continued to improve with daily usage. My cognition seems sharper, I type faster and more accurately and I feel as though I am learning quicker. I have noticed fantastic quality across all of the ND supplements I have tried. For those that care about their health, this is the only option.

It's almost as if it just makes your day 5-10% better. No, it's not like taking a klonopin. The half life is relatively shorts so you're supposed to take it 3 times a day if that's what you need. I've only been taking it once as needed if I'm stressed because it's supposed to ASSIST you with stress. Remember to avoid dependency of needing it to cope. **Q: This product uses corn Ethanol (an oxidizer) as an extractor and two fillers. Of the 180 caps,18 grams, 2/3rds are fillers. Is this worth it??** A: Yes. Nootropics Depot is very reputable, and uses scientifically-backed extraction methods (alcohol in this case), formulas, and is third-party verified. They have quite the following on Reddit. I trust them above most supplement companies. I found this supplement very effective for brain fog, stress, and general mood boosting effects. **Q: Size of pill compared to a dime?** A: It's about the length of a dime. A little larger than a vitamin D pill. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The Only Supplement Company with Integrity (Tested) *by A***R on 26 May 2026* NootropicsDepot is provably the best supplement company in the industry...
