I just received my QSC order yesterday.
You actually do need to get some shipping confirmation from their customer service if you want to be able to identify and label your vials. Assuming you ordered more than one product from them. I ordered two and there is no way to determine which product was which without a message from their customer service.
My identification clues came along with my tracking number. Shipping was fast.
I'm starting to lean towards EWB's choices in the "price-quality-customer service, pick two triad”.
I also was linked to a series of videos which show QSC's manufacturing facility. This was also confidence inspiring to see, if the videos are legit. The videos showed high-speed automated packaging of peptide vials. It looked professional to my untrained eyes.
Email isn't a guaranteed communication method. There are many pitfalls along the way from source to destination inbox.
Wait a couple weeks. Then send a message. If you don't hear back in another message. In my case, it took a couple messages to get a response. And by the time I'd received my tracking and package identification tips, it had already cleared customs.
