Been training my ass off naturally for four years now made some good gains 6"2 235 about 10% bodyfat. In the last year ran a few cycles nothing big just winny and deca and a bit of test. My arms havent grown an inch for about a year now still stuck at 18 1/4. my chest and shoulders respond really well to training and i am wondering if i should consider bi/tri shots if, which AS would be best. Thanks guys.
