Really man its nothing special. I was thinking of doing halo+furaza or doing an Epistane run. Even though I am 21, I am waiting till I am 22&1/2 at least probably 23. I have much I can still do without it. And I am christian and dont get to have sex, God knows I am full of hormones......
Look around the supplement forum if you really must use supps. But roids Please do not take, its going to hurt you bro, seriously. We aren't being mean, we are watching out for you.
You should never get "bored"with supps. Supps are there to make lifting and building easier, not for a past time or hobby. Take a step back man. Think about having a wife and kids someday.
If you take some roids when you are 23/24 and do proper support and PCT, you will walk away with great gains, no permanent sides. You can still have kids, get a boner, be mentally stable, and not have boobies!!
Do them now, and you will never find the muscle growth you want. You may not be able to have children, you could screw up your hormones and your Emotions for life.
See you balls are still developing even at 18. You mess with em, they may decide they arent needed anymore. At 22-25 your body can rebound from a short term use of roids(2-10 weeks) with proper PCT and your lil guys will reinflate over time.
Just dont do it man. There are some 18 year olds on here that can give you great advice. I would point out Texas, the guy is a beast among beasts. And there are others too.
