Man just a warning...I know its been posted here lots already.....but man if u can avoid shot to your quads....do it....my ass was sore and i did my quads I had to stay away from work for two days because I could not walk....just standing on the leg will bring tears to your eyes.
Also dont be cheap spend the 35 cent each for more needles and change it when u ready to inject.....goes in like your butter.
And to al the guys on this site....thanks for all the info....
