I have been using meth for a few years now, and have experience most routes of administration, including intranasally, sublingually, intraanally, orally and smoking it.
Everyone knows that amphetamines will reduce the ability to get an erection, everyone knows what I'm talking about here. It's more difficult, but for me its never been a problem. A problem did come about when I started smoking meth frequently, it didn't feel much different from other methods, but small side effects began to manifest, including loss of erectile strength
Since I stopped smoking meth, the problem has got better, it's still worth noting though. Has anyone found any way of restoring any lost strength?
I read an article (http://www.herbolove.com/article.asp?art=193) about how someone had damaged his penis through meth use, however by comparison that case is extreme, on this site a special cream and taking their pills is suggested to improve the problem. I'm a little hesitant on buying a product like that though.
The blocking of the re-uptake of norepinephrine (adrenaline) is the reason for meth to reduce the blood flow down there. I noticed something when smoking ice (4-Methylaminorex), which does not effect norepinephrine I believe, nearing the end of the duration (~16hrs), a rush or seratonin or something is felt and quite an increase in blood flow, has anyone else found this?
