yup it all depends i used some t400 once and i thought i was going to have to go to the ER it hurt so bad. Then a test 500 blend didnt even feel like a bruise the next day.BiggerStronger said:I've had 400mg/ml test e that was painless. However same batch on someone else crippled them. It really depends on the user and how your body reacts to the BA/BB content. 500mg/ml is most definitely do-able but it may or may not be painful depending on how you make it and how your body reacts.
