As above and more - I used to shoot winny in the biceps and triceps as an experiment but you can shoot it anywhere. It all comes down to the is spot shooting of any benefit? When I did it, it was as an experiment...
One thing with winstrol (however u take in - intramuscular or swallowing) due to its half ife should be taken daily not eod but you can take it every other day but during the days you do not take it, it will be of not benefit.
For best effects, take it 2-3 times daily.
