im just putting them into my bi's. they are now finally starting to grow, the shots are easy, and lifting after taking shots is even easier, but thats just me though. i've put about 16cc's into each bi so far, they should be really up at about 20cc's. i do 2cc's ed or eod, i take time off if the ol bi's are a little sore. results are looking very good so far, and it will only get better
