Fair enough. Sorry, the boys we're kinda being rude.
You didn't answer the question though, how tall are you?
K here's the thing...
1.) you shouldn't have run deca alone for a 1st cycle. But whatever, that's in the past, and MANY have made the exact same mistake.
2.) you aren't giving yourself enough time to recover between cycles.
3.) I doubt you're running a proper PCT after your cycles... running a proper PCT (post cycle therapy) will help drastically in determining if you keep your gains or not.
Anyways, in my opinion, you should give your body a long break from gear. You do NOT need to do deca, tren, and test right now. Those are pretty harsh compounds, you're still young buddy! Here, I'll give you some literature.. read up on it, and get a better grasp of what you've actually done to your body from these past 3 cycles...
