I add a dusting to my morning coffee because it is water soluble and the dosing is extremly small. I don't do this every day. I am actually afraid to. The first time I gave this a try, I noticed a change within a couple days. It seems I am able to make associations that I haven't been able to make for years, and it comes intuitively. It is extremely easy to overdose. I have accidentally done this once. A little chunk fell in. I had to lie down the rest of the day, ended up throwing up, not fun. But just don't do that.Edit: I have found mixing the tip of a spoonful into a mix of other herps for capsul fill eliminates the risk of overdosing.

I was so impressed with the high quality of my first Bulk Supplement purchase (DMAE) that I keep ordering more I believe I have ordered a total of five products from them now and plan on ordering a couple of more. I have heard complaints about some of the zip lock seals not working on some of the products. I had that problem with one product. The product was a very fine powder and it embedded in the zip lock seal. I just took a tack (pin, needle, whatever) and ran it inside the zip lock seal to clean it out. The bag seals perfectly now. This product is a fine powder and it is actually packaged in a smaller zip lock bag inside the bigger one. No problems with the seal on this one. They also have a huge array of supplements they carry.As a side note, I have had a couple of questions on some products. I can say that I have received very good customer service from Bulk Supplements. I plan on doing business with them for a long time.

Beware…My son and wife ended up in ER vomiting and and diarrhea! The dosage is not accurate on package. ER Doctor said don’t take unregulated product from overseas!! Absolutely the worst reaction I ha

I have issues with getting distracted during my studies, staying focused on assignments, and working on things absentmindedly; some expected woes of a college student. Along with my basic nootropic/supplement stack (Piracetam, Choline L-Bitartrate, Caffeine) this stuff really makes a difference. When using Huperzine A, along with my stack, I tend to ignore thoughts that would normally distract me, develop ideas that are much more sound, and have a distinct sharpness when I articulate myself.I'm not going to claim that Huperzine A along with my stack alone allows me to ascend beyond my issues, but I'm convinced that these help me when I set my mind to a "get-ish-done" mentality. This, along with other nootropics, won't make you the big brain on campus, but if you're willing to push yourself to just sit down and toil away at something, this will definitely help. As always, your mileage may vary.

MALTODEXTRINI’m rating this a neutral 3 solely because I can’t skip the star rating. I didn’t try it and the issue is entirely my fault.I’ve purchased from Bulk Supplements for years because the products are usually just pure, single ingredients and I have a history of anaphylaxis to corn derivatives which are in most supplements. With this one I read the reviews & decided to take the risk of carefully dosing, BUT I did not read the package label as well as I should have and missed that there’s maltodextrin (a corn derivative) in this product until after I’d opened it.

Huperzine-A is an acetylcholinesterase inhibitor, which means it stops the relevant enzymes from degrading acetylcholine, so that we have more of it in circulation. Used in Alzheimer's for this reason, and supposed to help with lucid dreaming as well.That said, organophosphate pesticides also work by (irreversible) acetylcholinesterase inhibition.I have reason to believe that my system is in general a "choline hog." I had been taking choline along with some huperzine-A tablets for a while with no great effects, but when I received this stuff I had an intense experience of rampant undegraded choline. The dosage is very small, and I took a small dose. But I had, essentially, a small version of organophosphate poisoning for a whole night and into the next two days. Acetylcholine governs the parasympathetic response, so think all the parasympathetic activities--massive salivation, diarrhea, only not vomiting with supreme effort, slowed heart rate... as well as extreme muscle cramps, hallucinations, muscular weakness, slurred speech, and extreme fatigue. If I hadn't understood exactly what was going on, I might have been scared.Huperzine-A has a fairly long half life (12+ hours), so this went on for a long time. The best I could do was stay under the covers and try not to move at all.I was sure that the choline+huperzine A combination was what did me in (when I thought it would make me feel great)!So less than a week later, I tried it again. This time, I took a much lower dose of huperzine-A, no choline, and I took a small amount of anticholinergic (cheap diphenhydramine) to inhibit any excess circulating choline.Long story short, this time I got really sick again, maybe marginally less bad but only marginally; just that it was a delayed onset (perhaps protected by the diphenhydramine initially).It's possible that I affected my receptors in a negative way with the first "trip" and that this is why it was bad the second time. It should also be said that I have a history of odd or paradoxical responses to herbs and supplements (although up to now I thought this was just with GABA-ergic and endorphin-impactng substances). So it may not affect others the same way. But at this point, I don't want to try huperzine-A again for a LONG time!!Once again, those huperzine-A tablets (which weren't cheap) did absolutely squat, so you can be sure that this is the real deal.
