This my first time using anabolics im 5'11 170lbs 19 years old

I bought vet grade Test-E 200
i took my first shot today seeing that its only 200mg for 10 weeks i was wondering if that was kind of low because im seeing that everyone else is doing 400mg a week. Is what im doing going to give me gains or no? I hit the gym today after the shot and felt like a monster, maybe cause im so young i dont need as much test?
