For this question I would suggest a broader search with google and look for top rated or something. Not sure if we can even give a brand name for the cheapes winston. lol Sourcing rules are kinda strict; maybe because if one can source one thing why not another and so on. idk.What Type of Phenibut like brand do you think is best?
Maybe there will be other answers but there may be some posts or threads available in the search function on the top of the webpage. Good luck with that I find it more fruitful to punch in say "safely alprazolam bluelight.org" or something like that but with your particular search terms.
As for using phenibut to quit aprazolam (xanax), I personally found it helps greatly with the cravings. This is to say that I would not depend on it to safely get off of benzodiazepines of any kind. After one has weaned (tapered down) benzodiazepines to a minimal dosage and basically dropped the intake of benzos it may help with some easment of sorts that are subtle and lasts a while. One would not want to get all fucked up on phenibut and get dependent, sick or in worse condition that before. If taken like twice a week or every three days at a "maintenance" dosage the repercussions from dropping phenibut are negligible or unnoticed in my experience. We are not all the same so your mileage may vary.
Be careful and stay safe, ya heard?
Peace
