Osta Rx at 19 yrs old, Side Effects?

I AM 19 years old can i try it ,its a sarm what sides does it have

Wouldn’t try it if I were you. At 19 you need to get in years before you attempt. Osta can shut you down, not as much as roids or ph’s. PCT may be needed. Work as hard as you can on compound lifts, eat well, and down the road run a cycle of something. too early in the game for this.
