Well well well this is where my expertize comes in handy. I have a collection of Hamilton syringes 10µL (MICROLITER)I could cup that puppy of his and draw out a full injection from beneath one of the fangs making sure there is still enough left for her to feed. And ask him to inject him self with the venom.
On another note I have a petshop close by with white lip tree vipers and I am sure they wont mind having him feed one of them by hand.
My best advice on this topic seriously is to get him to a psychiatrist IMMEDIATELY from what I read he needs help and bringing the Tarantula community in, is only going to give us bad name seriously, we have it difficult in a 3rd world country already where we are not even allowed to import new blood lines for our own T's, not to mention those hard to get T's.
I have already heard 2 scary stories beginning this year, which I am not going to share, for the sake of all T lovers.
Please people know what you are buying, and read up on the species. And get your hand on "Tarantulas Keeper's Guide".
It's like buying non poisonous snakes or buying exotic poisonous snakes. "cold shivers" People actually spend money to go for handling courses. No not to get bitten, but to be safe and enjoy the hobby "and not to get bitten

"
