Nootropic dietary supplement compounds are quite safe assuming you have a legitimate finished product...I would be much more worried about higher chance of danger from ingesting contaminants from dietary supplement nootropics as the market is not regulated as the pharmaceutical market is...and low purity/contamination with harmful impurities (such as lead, other heavy metals, microbiological impurities, and who knows what else?)
It's not like the conventional nootropics are available at the corner store. No pharmaceutical company with a name manufactures nootropics...it's always some no name lab in China whose manufacturing operations are not known to be in accordance with the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH). There are some chemicals used to manufacture chemicals, and others to manufacture drugs for human use...ideally, you don't want to be ingesting reagent grade nootropics manufacutured by the lowest bidder in a Chinese "chemical factory..."
I'm not trying to generate any hysteria; but I would like to point out the extreme irony in even mentioning the word: "Safety" when one is ingesting high doses of racetams and other dietary supplement products produced in China and sold in the USA as "food products" that are in fact sold online without being screened for contaminants..ask your doctor: which they think is more dangerous: taking unregulated dietary supplements produced in unknown labs in China or taking a prescription for Dexedrine written by ones doctor...if your nootropic supplier implements rigorous quality control, that would make much more sense...but otherwise...hmmm, I'd stay safe and not mess with stuff that barely seems to work anyways...
The dietary supplement market is infested with impurities...it would be naive to assume the nootropics could somehow be shielded from any and all contamaination...I would worry that these rare and unregulated products would in fact be even more likely to be contaminated considering they are synthetic compounds made in no name labs in China...take the purest stuff you can, if you are going to take Chinese imported "food products"...imported Chinese food isn't exactly my choice for cuisine...

http://www.ich.org/c.../276-254-1.htmlConsumer Reports (May 2004) and the “Dirty Dozen” unsafe herbs still readily available
· “CONSUMER REPORTS has identified a dozen (supplements) that … are too dangerous to be on the market. Yet they are.” Introductory paragraph in red ink.
· Factors contributing to unsafe supplements on the market.
· “ ‘The standards for demonstrating a supplement is hazardous are so high that it can take the FDA years to build a case,’ said Bruce Silverglade, legal director of the Center for Science in the Public Interest, a Washington D.C., consumer advocacy group”(pg. 12).
· “The FDA’s supplement division is understaffed and underfunded, with about 60 people and a budget of only 10 million “dollars)…” (pp. 12-13).
· “…Overwhelming opposition from Congress and industry forced it to back down” when the FDA first tried to regulate ephedra in 1997 (pg. 13).
· The public assumes a greater degree of government regulation than exists – in a 2002 Harris Poll of 1010 adults, 59% of respondents believed that supplements must be approved by a government agency before they can be sold to the public, 68% thought the government requires warning labels on supplements with regard to potential dangers, and 55% thought that supplement manufacturers could not make safety claims without solid scientific support.
My usual favorite references from scientific research on dietary supplements available on store shelves in the USA:
A study of ginseng products found tremendous variability, with as little as 12% and as much as 328% of the active ingredient in the bottle, compared to the information on the label
(Am J Clin Nutr. 2001. 73. 1101-1106)A study of 59 Echinacea products from retail stores analyzed by thin layer chromotography showed that 6 contained no measurable Echinacea and only 9 of the 21 preparations labelled as standardized extracts actually contained in the sample the content listed on the label. Overall, the assay results were consistent with the labelled content in only 31 of the 59 preparations
(Arch Intern Med. 2003. 163. 699-704).When the FDA announced in 2003 a proposed rule to establish good manufacturing practices for supplements, the FDA cited data that 5 of 18 soy and/or red clover supplements contained only 50-80% of the quantity of isoflavones stated on the label, and 8 of 25 probiotic products contained less than 1% of the live bacteria claimed on the label.
In 1998 the California Department of Health reported in a letter published in the New England Journal of Medicine that 32% of Asian patent medicines sold in that state contained undeclared pharmaceuticals or heavy metals, including ephedrine ( a stimulant), chlorpheniramine (an antihistamine), methyltestosterone (an anabolic steroid), phenacetin (a pain killer), lead, mercury, and arsenic
(N Engl J Med. 1998. 339. 847).A study in which 500 Asian patent medicines were screened for the presence of heavy metals and 134 drugs found that 10% were contaminated
(Bull Environ Contam Toxicol. 2000. 65. 112-119).A study in which all unique Ayurvedic herbal medicine products were purchased from all stores within 20 miles of Boston City Hall found that 14 of 70 products (20%) contained heavy metals and that if taken as recommended by the manufacturer, each of these 14 products could result in heavy metal intakes above published regulatory standards
(JAMA. 2004. 292. 2868-2873).Adulteration of imported Chinese dietary supplements sold in Japan is responsible for 622 cases of illness, 148 hospitalizations, and 3 deaths
(Report of the Japanese Ministry of Health, Labor, and Welfare. September 20, 2002).A 2002 Bastyr University study of 20 probiotic supplements found that 16 contained bacteria not listed on the label, 6 contained organisms that can make people sick, and 4 contained no live organisms.
PC-SPES was removed from the market in 2002 after it was determined that it was adulterated with the prescription blood thinner, warfarin.
Peace out.
