Hello - first of all - don't run Trenbolone. That's a way too harsh cycle for you.
Second - Testosterone 500 is a high concentration of Test. You can run it, but you are likely to experience PIP (Post Injection Pain). I would recommend to go to Test alone (but a different form of test). Anyway, if you go for it, never use more than 1 ml per week (500 mg/week). For a beginner, you could run even less (such as 0.3 ml per week = 300 mg/weekly). You got to split testosterone dosage throughout the week. Such as 0.15-0.25 ml Monday (150-250 mg) and 0.15-0.25. ml Thursday (150-250 mg).
Maximum you can add is Anavar, but I still wouldn't. 2 tablets a day is maximum. For 6 weeks.
You can try: testosterone week 1-10 300-500mg/week and anavar the last 4 weeks (week 7-10) 25-50 mg/day (split daily dosage).
don't forget a PCT plan and have anti estrogens on hand
