No, it was because I have issues associated with low levels of oxytocin like inability to remember faces and people and low desire for social/sexual relations. I did not know it was oxytocin I thought it was selank.
I honestly don't believe the stuff about Chinese products being so low quality. Plenty of people have bought raw powders and they have turned out to be 99% pure.
To paraphrase Forrest Gump, "buying research chemicals from China is like a box of chocolates. You never know what you gonna get.".
There are certainly plenty of Chinese synthesis labs that have good equipment and know what they are doing and produce a good product. The problem is, when you're dealing through Alibaba you generally aren't dealing with them.
What you're dealing with is some little Mom and Pop middleman seller. They deal with the labs, mark up the result, and sell it to you. They might buy their compounds from a good lab, then again they might not. They will generally buy from the lab that gives them the best deal that day and you can't even count on consistency from purchase to purchase as they will make their buys based solely on price at the time they order.
Chinese culture has this thing about a seller always trying to get the best deal no matter what. Any seller that leaves a fraction of a yuan on the table is considered to be a fool. As long as you can get away with something, like selling an inferior product or even a fake product, you should. I have dealt with Chinese contract manufacturers and they are fully capable of producing just about any quality you like. The problem is that once you pick a supplier and sign off on his first article, he busily starts slipping the quality up to the point you notice and then complain. So, if you aren't testing every lot his shipping you, assume at some point he will ship you talcum power in place of whatever compound you have ordered. If you notice he will apologize profusely for the mix up, ship you the correct product, then in six months he'll be right back to his old ways trying to see what he can do to cheapen his product that you won't notice.
An individual buyer in this environment is severely disadvantaged since they know that the chances that you'll test anything are virtually zero. That's why I don't order from Chinese suppliers. I don't have the ability to test their product so I assume that at some point I'll receive something adulterated.
