there are different supplements that help calm you down. GABA is one too
let me ask you this. are you taking any stimulants or drinking coffee etc? if so you need to stop. caffeine inhibits these calming agents in your body, giving you more anxiety
that is why you see coffee addicts always shaky and nervous
you shouldn't need to take something to calm you down, our bodies naturally have those things. you need to really reexamine if steroids are a good choice for you
