A source does not stay a source long if he is not discreet in his packaging. The issues you have are either you order in your name and not a alter ego and have the parents wonder just who "John Hammings" is and why a package just showed up for him, or you order in your name, and if there is an issue (seizure for example) then your name is on the radar. At least with a alter ego you can "WTF? That aint mine" if it comes to it. Kind of hard to do when its addressed to you. Going with a PO box sounds good, but now you have to wonder if the nosy old biddy at the post office is going to wonder why/whats in the package you just got. Not to mention alot of Post Offices will not put a delivery in the po box if it doesnt match the po box renter (I spent 6months getting the PO to agree to put my business mail "joebloetrucking" in the box I had rented in my personal name without sending half of it back). Once again puts you into ordering in your own name. And forget about renting a box under a alter-ego name. ID's, local address, etc are all requirements post 9-11 to rent a box. Even if you do manage to get a alter ego box, if it needs a signature from the alter ego that packs done, as your id wont match the name, so you cant sign for it.

Now, having said all that, I will add this... If you have the money to order gear, you should have the money to have your own place. You said you have been doing research, but one of the first things is to have your priorities in the right order, and if you are more worried about cycling and getting a package in under your parents nose then having your own place and living your own life, your priorities are NOT in the right order. Secondly, 20 is not the age to be doing a cycle. Have you even done bloods to see where your natural T is at right now? Hopefully Frankie will be along to share some more info about starting too young.

run, run as fast as you can. i hear they ship a mini gnome that pops out of the box and lives in your house and eats your food. but seriously bro 20? come on, my test was so high at twenty i couldn't look at a girl without it running down my leg. your really killing your natural growing potential here. unless your thinking on stage at 25 then you need to slow grow.

Bro first off you going to get shit for your age. You said you did research but not enough. Suprisingly your first cycle was just Test E, I hope you did your PCT after... Secondly there is no "safer" way... P.O. box or actual mailbox is no different. Lastly if your scared that your mother and father will be suspicious then you shouldn't be using gear the only reason why I'm even typing this is because I did my first cycle at a young age, you probably wont get any better help on here then what I have just finished telling you.
