I don’t claim to have all the answers; I just know what works for me. I take L-Tyrosine the first thing upon waking up in the morning on an empty stomach and with water. It helps me keep mental focus and gives me energy, and this is why I was taking it. I noticed it also helped my libido and then I read that it’s thought to have this effect. Just google tyrosine and libido and you’ll find some articles. Don’t take it with food or any other vitamins or amino acids or anything other than water, and be without food for a half hour at least. Don’t take more than 1g a day and don’t take it at night. I’ve read similar things about choline and its effect on libido/performance. I take it daily.
L-Arginine I use in one of two ways: for the HGH “pump” I told you about above, in 10g quantities taken on an empty stomach (2 hours after eating or drinking anything other than water has worked for me). And I take it about an hour before I anticipate sleeping with a woman. It is supposed to release or make available nitric oxide, a key to the proper functioning of an erection. It seems to work well in 2-3 gram quantities for this purpose for me.
Testosterone is key too especially for having desire, and for enhancing that I will take Tribulus Terrestris for a day or two now and then. It is supposed to enhance testosterone levels.
The final thing for me has just to make sure I don’t sleep with a woman without having eaten recently or reasonably well in a day. This seems funny, but I traced mediocre performance in two cases to the simple fact that I hadn’t recharged my batteries with food. It is also best for me not to eat a bunch right beforehand.
I haven’t tried the things you mentioned for this purpose or needed to do so. From what I know melatonin would have a dampening, not enriching, effect on libido. I have used Levitra as a hedge against deflation more than anything, but I find Arginine which supports the same basic nitric oxide building process works as well for me. Once in awhile I use both, when I really want to be sure.
