Sober ex-drinker wants to try alcohol again.

Hello. I’m 24year old guy. I stopped drinking alcohol when I was 20 and havn’t really had any alcohol for 4 years now. But i’ve been considering to try some beer sometime because i’m kinda socially awkward/shy guy and beer seem to be some sort of a social life helper, but i’m an athletic guy and i’m afraid it will slow down my gains and idk if i should stay being sober or try some drinking? What do you think?
