hey bros today was 3rd shot and didnt hurt, is that normal?

Ive done a shot on mon, wed and today which by the way is 200mg eq and 200 t200 each shot.On mon I injected in ass and it hurt bad ,on wed I did it in delt and it hurt and today I did it in ass agian and it didnt hurt.Since it didnt hurt does that mean I still went into a muscle,what i am asking is did I waste it since it didnt hu9rt like the other 2?I use a 1 1/2 inch 23 gauge needle by the way.. please help

Some hurt some don't and using a 1 1/2" pin you will be in the muscle unless you have a very very high body fat

my t200 and EQ shots...usually never hurt...unless in my delt...then it ache for a couple hours the next day
