primobolan 100mg and winstrol tablets 10mg

HI guys

First excuse my english as its not my native language, i ll do my best!

All right, i am about to start my first cycle of primobolan/winstrol, i got some gears from a guy i kind of trust but still i would like your opinion about it.
few things makes me want to post this thread:

- For the primo the bottles are not the same size, some are a little taller than others.. not really bigger though. is it normal?

- For the winstrol, i never seen this stuff out there so i have no idea if it could be fake or real...

Thanks for you help guys!
