just gonna throw this out there, I grew up in Jersey and most the kids there were juicing before they lost their virginity. Not everyone is fortunate enough to find the right guidence on how and when to cycle. And the pressure of being the one thats not all huge and buff is pretty tough to deal with at times. Being 235lbs is huge for a 17yo, whats the rush, just be patient and wait a few years. In the mean time research and be knowledgable before you jump into AAS.
Even tho a compound like Dbol is supposedly safer on joints, you really need to stay hydrated. If you dont drink enough water your joints will dry out form your kidneys flushing out toxins. In sports like football, players can sweet out 5-10lbs of water.
