For about 6 months last year I was on a cocktail of supplements. Every day I took:
Piracetam (2-5 capsules)
Alpha GPC (Choline)
TribX90 (Tribulus Terrestris)
Huperzine-A
Tyrosine (random amount I'd shove into a capsule)
For about two months, I felt like I was back 75%, some days 85% (the remaining 15-25% is hyper sensitivity I remember having, that I only get from buspar now when it worked). I actually started making sex tapes and making money from them. I had morning erections almost every day for about a month. Arousal was very easy for me, and I had stronger erections, precum, and the volume of ejaculate was much higher.
These effects lasted a few months, slowly wearing off. I also had a bit of a manic episode, by a bit I should say severe, probably I'm guessing because I was taking too much Huperzine-A. By a severe manic episode I should say I started thinking I was the savior of humanity, which I think is a state of mind that a lot of people come near, but is unsustainable without being hospitalized. That's a very different topic of conversation.
I took buspar a couple of times during sex. The first time it worked great for me. Was able to have sex all night. After that it stopped working as well, and I've since run out of my supply, but it works well enough that I'd keep a supply on hand for times I want a boost. It's not one I can take every day without experiencing personality changes.
I read that Piracetam can cause depression in some people. I was becoming very depressed at the end of the 6 month period, and stopped taking all supplements altogether. This ceased the depressive symptoms for a few days, then they returned, along with having no ability to have sex again. I started taking Alpha GPC and Huperzine again, and I immediately felt better (depression-wise anyway).
I've also bought St. John's Wort, and Oregon Grape, and have just started taking them in conjunction. This is my experience after taking St. John's Wort:
My depression subsided a bit, my thoughts seemed clearer. I was, however, fully unable to get an erection. I had taken a single pill. Numb genitals, and couldn't achieve an erection to save my life. It reminded me of how I felt when this first happened to me. I threw the bottle away and vowed never to take it again. The next morning I felt like shit. Then suddenly I felt a wave of positive emotion and got a spontaneous erection at work. I felt great the rest of the day, and bought Oregon Grape on the way home, and took a couple. I took a nap that night, and woke up with a prolonged erection. It happened again this afternoon, although I didn't have an erection when I woke up today. I just took another St. John's Wort, and about a half hour later I've got the numbness and inability to achieve erection again. I'm going to see if it "clears up" again like it did the first time, and I feel better after.
Sorry if a bit of this is rambling. I think I got all I could from taking Piracetam, and will probably not take it anymore. The Alpha GPC and Huperzine I will keep taking, along with the Oregon Grape while it lasts, and I'll see what the St. John's Wort does (unless someone here warns me against it). I'll probably also buy TribX90 again, although like all tribulus terrestris, it seems to work well initially and then wear off unless I switch brands or cycle it on and off.
I was also exercising during the peak of the two or three months I was back 85%. I've since stopped for lack of motivation to continue after the sexuality began to fade. I should start again, but it's difficult to get back on track with that.
Hopefully this is more useful than it is not.
