I started at 18. Im 40. Man I wish I could go back and hold off until I really needed it. I hopped on for confidence/self esteem issues. I wasnt pursuing a career in athletics. Money wasnt on the line. Ive been pinning myself ever week for 15+ years regularly. The only thing I regret is not waiting till I was older. I didnt know how to eat. I learned how to eat my first cycle. I wish I could have seen how far I could go naturally, but I couldn't wait. Steroids may seem popular now but... things go in and our of style... I bet natty guys are gonna have alot more respect from society as we see more and more steroid addiction.

Before you decide if you should or shouldnt... obviously research everythinf youre putting into your body, potential risks etc... but... if you havent... commit to a few months of really going at it with eating. You look like youre lean and have a pretty good metabolism. Im guessing youre trying to get jacked? Ya gotta learn to eat. Spend 3 days stuffing yourself. Eat to the point where your stomach is stretched out. Youll start taking shits every hour or so as your body gets used to it. Throw down a shake before bed. After a few days, your stomach will be stretched out, youll be craving food every hour. I eat 6-8 small meals a day plus healthy snacks every hr in between, plus shakes... eating is harder than lifting for me. It really becomes a challenge trying to maintain size.
Id suggest giving it a real go trying to gain some more weight naturally. If you hopped on now, without knowing how to bulk naturally, youre gonna rely on drugs for the rest of your life.

From the looks of it you are very young. Also only 1 year of training is nothing. Spend the next 5 or so years seriously training and dialing in your diet, lifestyle, and training. You want to be close to maxed out before you hop on at a young age. Assuming you are not hypogonadal there's no reason you can't make gains for a few years. Also you really need to learn to eat right for your goals and do everything right before just throwing in the drugs. If you have everything dialed in and are close to your genetic limit, then when you hop on things will go so much smoother, and you can make solid progress from moderate doses.

Too young, keep building foundation and eat.

You look young man. Training for a year isn’t really anything in the grand scheme of things. Your body though. Get your blood work done.

Looks like you were too young for the site, you need to be 25yrs. You should go get your testosterone levels checked first to see where they sit and if you hop on your first cycle should be Testosterone only and hit the gym hard. There is a lot you need to learn about Test cycles first though like how to keep your estrogen in check and how to come off cycle. If you are under 25 honestly unless your test level for some reason is low, you should stay off gear until older because it can ruin your chance to have kids and all.
