I have used a fake name many times and have never had a problem. Even if I were to use my real name, I am not a homeowner so the package name would still not match the homeowner's name. I have rented like 15 different places over the years moving back and forth for school, internships, and jobs, never changing my official govt address on my driver's license, and received hundreds of packages (from the US and China) and had never had a problem with my package being held or not being delivered because I don't officially live somewhere.
Now I can't guarantee that you'll have the same experience. I have seen some drama on MesoRx about people not getting a refund from the vendor if a fake name was used. I am willing to hypothetically lose a couple hundred dollars now and then to prevent my name from being added to some permanent customs list where everything I order for the rest of my life will be closely monitored. Yes, I am aware that if the govt really wanted to find out who ordered the package, they probably could. But no one is doing that level of investigating for a tiny package of technically not even illegal research chemicals. And if they did, there are four people in my house who move in and out every couple of months so good luck figuring which one of us it was.
Again, I am not recommending anyone else use a fake name. Just sharing my experiences.
