Are ais enough to prevent growth plate closure.

[AnatolianSlayer271]

For some context I am 16 and about 5-8 or 9 ish havent measured a good minute, I am a bit of a late bloomer. I wanna hop on around 200-300mg test e to gain some muscle mass, but mainly for bone mass. But I don't wanna close my growth plates prematurely, I keep hearing different options. Also considered HGH, Anavar etc.
