The racetams are pretty cool stuff. They all do their own thing in their own way, but ultimately improve overall cognition. The strongest easily available on the market is Pramiracetam which is fat soluble and tastes like chemical warfare, but it has the least of "noticeable" effects until mental activity is engaged. Aniracetam is the other fat-soluble racetam which is considerable more popular and is often noted for its sedative effects.
Of the water soluble ones, Piracetam and Oxiracetam are the popular choices, with the latter being the stronger out of the two.
The third most popular one that is not widely available is called Phenylpiracetam, a drug developed for astronauts to stay awake. Many reports of its great cognitive enhancing capabilities can be found online, one even mentioning an accident synergy with a few other nootropics that resulted in a temporary photographic memory. The phenyl ring makes it a killer improvement over the other racetams in terms of a brain drug. Wikipedia states it as being a banned olympic substance due to its physically stimulating effects.
It goes by the brand names Phenotropyl and Carphedon when taken in tablet form. These can be bought online at a few Russian sites. I'm not interested in tablets. I like to mix, and I see a future in finding nootropic synergies for various mental effects such as focus, memory, and creativity. I have a crude crushing mechanism, but I'd rather not pay dearly for phenylpiractem tablets at premium price if I can get get powder for wholesale or distribution price. There are some overseas companies offering to synthesize it, but chances are this doesn't pass US standard levels of purity as a supplement.
I'm looking for an American supplier or laboratory who would synthesize it. I'm pretty sure a bulk nootropic store or an ebay store wouldn't mind buying a kilogram from an American lab if there is enough interest. If enough agree to buy 50g at $1/gram, the store can cover their costs at around 10-20 minimum (if lab charges under $1000/kg) and the store can mark up the price as needed afterwards. Typical doses are between 100mg and 300mg taken 2x a day, so it would cost at most 60 cents a day for this super nootropic. That would be worth it for me, and I bet for bunch of other buyers.
Let me know if you are interested in approaching these stores with me or if you already know an American supplier.
