QSC is a huge, very huge, grey/black market company. It seems that some people want regular market customer service from a company that might be working in a fuzzy area of the law in their own home country. Out of all of the Chinese companies, QSC already gives the most Western like customer service. Most of the Chinese vendors will not even give a price list with prices, and expect the customers to tolerate quotes and haggling.
Is QSC labeling terrible? Yes, it is. But how do you think they get so much of their product through customs? Are they slow or sometimes errant in getting tracking out? Yes, they are. But they are also a limited crew getting out thousands and thousands of orders, and mistakes will happen, but the product always reaches the destination with only a few exceptions.
Where else can you get such a wide variety of oils, peptides, sarms, PCT, orals, raws, and so on? And it's not just a large variety, it's a large variety at high quality for dirt cheap prices that beat, on average, everyone else.
The complaints listed in the comments are valid, and I can see some legal corporation caring, but what other Chinese vendor with prices even remotely close to QSC 's prices and quality exists let alone cares?
With all of that said, it would be great if QSC could address all of the complaints here, which seem to orbit around 1. tracking, 2. labeling, 3. taking orders without product when out then giving credit, 4. blaming company assistants instead of taking company responsibility when actual problems arise. Did I miss core complaints?
QSC is an absolutely great company, but like any company could most certainly improve. From an economic theory point of view, if they are lacking enough, someone else will fill their shoes. Those are some really big shoes to fill though.
