Phenibut - Did not work
I have used Phenibut in the past with excellent results and was able to sleep through the night. Unfortunately, this formulation didn’t work, even at a higher dose. It was more than twice the price, which I was willing to pay if it worked. Very disappointed.
Response from CosmicNootropicJul 11, 2025
Hi there! Thank you for sharing your experience. We’re sorry to hear that this formulation didn’t meet your expectations, especially given your previous success with Phenibut. Effects can vary depending on individual sensitivity and response, but we truly understand your disappointment.

I really only stay coming back because I can continuously get Phenibut. But how come I can only get 3 packs at a time?
Response from CosmicNootropicJul 11, 2025
Hi Joshua! Thank you for your feedback. Unfortunately, due to regulations, we can only send three boxes per order.
