So you're going to inject 125mgs every week totalling 250mgs? That's a very small dose (trt) dose of test. And it's best to split the injections twise per WEEK. Not once a week.
And prop is not the best for bulking and neither is primo.
Run the t-bol at the beginning like mentioned. And i'd run 500mgs of test e split twice a week. Like 250mgs on Sunday and 250mgs on Wednesday.
Good luck
