u should go with like a combo... 100mgs of prop/100mgs npp in each ml.... most of the ug labs are gettin into that. i know a few off the top of my headcityhick said:I love the prop I am on right now. But every shot hurts till the next. Usally the first shot of a cycle hurts and then its smooth sailing. But this is my first run with prop and it does sting. I mix my shot 1/4ML Deca(300mgsml) 1/4ML Test E (250mgs/ml) and 1ML of Prop (100mgs/ml) EOD and it still stings. Oh well. Feel crazy strong.
