Have a couple shots of bourbon to calm down and just hit it in the same glute you did it in successfully last time. Maybe this just isn't for you, if you can't handle the pins, might need to move on and stay natural. There is a lot of hormone head games that come with this type of supplement, if you can't get past this, you might not be cut out for it. Nothing wrong with that, it's not worth screwing with your head, take a break and try again next year.
