quality and quantity

the bulk option really saves money compared to buying all the small bottles of theanine. It's equally as strong as the other brands or close enough as far as I can tell so I recommend trying this brand for the savings alone.

Nothing fancy - just a GREAT product!

The powder is very fine, flavorless, and easily mixes into any liquid. I put it in my protein shakes for a boost and it's perfect. Don't bother with costly capsules and fancy packaging - this is the real deal: a quality product at a fraction of the cost. The expiration date is even 3 years from now! 😊

100% True ingredient

Big value save tons of money compared with other brands. No after taste. Real active ingredient inside. I can fall asleep within 1 hour and sleep thru the night. The only downside is hard to measure the right amount for each cup. I might try the capsules next time.
