If I was ever going to use test, I would find a junkie and ask him for help shooting the first time. They're pretty proficient with needles.
... making sure he washes his hands first would be a challenge... shit making sure he does spit aids all over would be as well
I would not go that route my friend.
How are the kids btw... , long time no speak; hope all is well. when it comes to family/children, You're quite an awesome role model my friend. I look up to you.
