Filling your injectors

[SmokinHog]

Just wondering how you guys do it. I bought a new one that has a longer needle but the holes go up 2 or 3 inches up the barrel of the needle. My old method of putting the injection in a small narrow cup did work on this monster. how do you guys do it?

Edit: Never mind guys. I guess I had eaten a stupid sandwich for lunch the day I tried to use the big one. It come with 2 needles, the diffuser needle and a needle with a single hole like a hypo. I can fill with the hypo and inject with the diffuser.
