I am an amphetamine addict and have been trying to improve some of the nuances of my use since a certain point. Recently I experienced a bunch of memantine + amphetamine. Impressions are not unambiguous. As expected, this will not completely prevent tolerance, but only some aspects. This substantially smoothed out the withdrawal symptoms, but did not eliminate them completely. I have better control over my urge to use, but I still crave stimulants a lot. I don't know if memantine prevented neurotoxicity, but the effects of amphetamine changed over time anyway. I don't know what exactly has changed, it's just that I'm becoming more manic and unbalanced, even though the memantine was supposed to prevent the sensitization. I am somewhat disappointed as I expected memantine to retain the effects of the amphetamine. I believe that this amphetamine sample, like most others, was far from pharmaceutical grade and contained amphetamine by-products/polymers due to improper synthesis. It really turned me into an animal in a matter of days, despite the most powerful neuroprotective. I have something to compare with, I didn’t use harm reduction methods at all with the previous sample and everything was great ...
