I feel for you, your brother, your family and the general situation. Please know I’ll be thinking of you guys. I had to bury a brother growing up. He was 5 and I was 10, I don’t wish that on any person friend or foe. I hope it goes as well as possible.
Provided you won’t have issues going through customs when you go home, there is nothing wrong with bringing a little bit of Nolvadex and or clomid with you just for peace of mind. Things to think about are, how easy is it to get in the country you are going to (sounds kinda bad but your brother might be prescribed some Nolvadex it is a cancer drug and chances are they over prescribed him so maybe that’s a source), what possible issues would you have bringing it (you don’t want to spend a month in a cell because you carried unmarked pills through customs), and lastly when are you going home because you might have enough time before you leave to figure out if you even want to bother with bringing some with you. I just wanted to make sure you thought it out before committing to bring some especially if bringing some is just for peace of mind.
The opened bottles of gear; as long as they are stored in a cool dry place out of direct sunlight then they will be good once you get back to them. Provided you use them within the next year or two and you only ever used sterile drawling techniques. Really they could be good another five years if store correctly. No dirty or used needles were inserted into the bottles, correct? Even a used syringe with a clean needle is considered a used needle. They put benzyl alcohol into the brew to kill anything living and to keep anything from growing, it also helps preserve the finished oil. If you are super worried you could get a bottle of benzyl alcohol and put like 1/20 of a ml into the bottles about a week before you want to use them again and that should kill anything that might have gotten in through the tiny hole the needle made when you drew the shots out.
