deca var isn't an injectable. You put it under your tongue. That is if you're talking about VPX products. When I was 16 I tried andro and I started breaking out because of that fact that I was so young and my testosterone was really increasing. If I were you at your age I would just be taking some of the basics like
glutamine, meal replacements,
protein powders, a lot of food, and maybe something to hype you up like a red bull. Trust me, I started when I was young and wish I would've waited. I was benching 365 lbs. at the end of my sophomore year and everyone was calling me a
steroid freak. When you start off at a young age and bceome something greater than other in the gym and they talk shit and down you for it by coming up with stupid excuses, it can really start to effect you ego. I always wanted to kick the peoples ass that said it but I couldn't. That's just my advice.
