I experimented with the product for a few months. As mentioned above, I found it more effective than pharmaceuticals, but it wasn't always effective. I didn't experience side effects or withdrawals.

You raise a good point regarding phenibut. The research suggests it can cause withdrawal symptoms from varying doses. The products intention is to provide a GABA type product that crosses the blood brain barrier, as most forms of GABA are poorly absorbed, whereas phenibut satisfies this objective.

The product maker claims the concentrations are all microdoses, thus safe. However to your point, without providing these details how is one to know.

My intention was to provide some non-pharmeceutical alternatives for remediating sleep. Turns out this product blends pharmaceuticals with vitamins, minerals and neurotransmitters. As such, I apologise for misleading anyone and recommend to do your research and experiment cautiously.

Thanks for the catch Mark.
