Is this your first cycle? If so, than you may have developed a tolerance to the chemicals and perhaps became a better shot?
Not tolerance like you're body isn't getting enough out of them now.. but just the general pip that some gear causes will go away after your muscle tissue and other parts have grown accustomed to what's in it.
When I say a better shot.. sometimes as noobies we tend to shake, go in at an angle, forget to push out air, pull the needle back out and have to reshoot. All these things will cause additional pain to the area beyond the virgin muscle pip.
If this isn't your first cycle... I don't really know what to say. lol
Perhaps you've started a new vial and it's not as Alcohol ridden as the previous vial. Maybe the gear before was contaminated and this is not? Maybe it's your first cycle in a while and you've done some noob shit the past few shots and you've worked out the kinks before doing this one.
I think it's safe to say, we'd probably need more information than "I was having pain before, now I'm not"
