primobolan alone is it worht it ?...how long and a good dose?

ok well i have found myself a reliable cheap source on some primobolan depot ( the injectable version) i have been looking ino it alot lately and i see how it seems like the most harmless roid...i know its still no protein powder but it seems to have hardly any side affect. It seems to have good ratings for weight gain and power and even a litle fatloss.......will it help me tryingto build only lean mass .........is it worth it to take it alone and does anyone know an doses .i wil be also taking protein supplements daily and maybe creatine
