According to nyles7 there are two NSI-189 forms: freebase and phosphate. Nyles7 explains as follow:
"The look and taste of the phosphate is totally different from the base. It would be easy to fake the base since it doesn't have a strong taste or odour. I'm not saying that will happen to you, just a possibility. The phosphate salt has a strong, not too pleasant taste."
Nyles7 used to sell both the base initially and then the phosphate. WuhanHenghedaPharm sells the freebase only as far as I know.
I would not recommend using the phosphate form nasally; I have had an hard time taking it sublingually, imagine what it can do to your nostrils.
I tried both nyles7 (phosphate) and WuhanHenghedaPharm (freebase) and I experienced the same short term positive mental effects despite having different taste and consistency; the freebase is fluffier (it reminds me potato starch).
WuhanHenghedaPharm is the only NSI-189 supplier in alibaba so it is not a random supplier as someone sceptically said. They are based in a Technology Park and have a website in English. According to nyles7 there are probably a very limited number of manufacturers of NSI-189. At the end of the day it is a new patented compound and legal actions can occur. I would not be surprised (my assumption only) if many of the online nootropic websites that sell it, source it from the Chinese company itself and resell it with a huge mark-up. That is especially the case if they sell the freebase form which is the only one sold by WHP.
There is no way to find out whether the compound you bought from any supplier is the right one or its purity unless it is independently tested by a reputable external testing company no matter what the source is and where it is based. I guess, only guess, that you cannot compare graphs of tests carried out on the two different forms of NSI-189, freebase and phosphate. I do not have any chemistry background so I might be wrong.
Do not assume that you have the wrong compound just because it does not taste as described in this forum thread considering what I just mentioned above.
If you do not experience anything for days after taking NSI-189 it could be possible that the short term mechanism of action, if there is any, beside the long term adult neurogenesis is not needed by your brain in the first place. As mentioned in my previous posts, I did feel positive effects right from the start and first dose with both NSI-189 sources. Someone might not experience short-term effects but only long-term neurogenesis effects. Just my 2 cents theory.
I doubt Neuralstem will sustain the financial cost of starting international legal actions against a Chinese manufacturer in a Chinese legal system in order to protect its interest on a compound that, even if quite promising, has still not passed all FDA tests/trials and reached the market.
