Here's what I'd recommend
Piracetam is great but for me I need to take a lot of it. If you have the liwuid take a few bottles in the first coulple days, otherwise take 3-4 tabs 4 times a day for about 3 days, then lower the dose....Some people get good redults from 3 tabs a day, but I find I need at least twice that. Also you want to give yourself a break wevery couple weeks because although it's very safe it puts some stress on your kidneys. Choline, take as much as you can...I personally can only get them in 250 mg tabs mixed with Inositol and they are hard to swallow, I'd like to get about 3 times the ammount I do but it's just touch sucking down all those pills.
Hydergine normally comes in 4.5 mg tabs, I'd recommend two a day, but some people get srtomach trouble from it, if so 4.5mg a day is a good "standard"dose.
With the Gerovital H3 if you have the real stuff from Romania manufactured by Sicomed in Bucharest it's good stuff, there are alot of fakes out there...I recommend taking 1 tab in the morning and 1 tab before bed. You shouldn't eat anything for about an hour afterwards. You won;t notice results for a while but if you take it for 6 months you should see some real changes...at least I did. You should take it I think 25 days on and 5 days off.
I know nothing about Lucydril, but b vitamins are always good....
Good luck..Oh and by the way I''m relly into nootropics and life extension drugs and nutrients, and I'll tell you the best thing I;ve found for memory and alertness, and just overall mood enhancement is Minurin (desmopressina) it's a natural brain hormone, and you haveto try it to believe it, it really works and you can feel it right away, compared to most of those other products you can tell you;re getting results.....some of the others like Hydergine and Gerovital work, but they take a long time before you notice they're working.
It's kind of like steroids, they work really well if you use them right, but they can costa lot of money and if you don't use them properly you don't get results.
Hope that helps a little.
