to lessen the pain of prop injections, the more u dilute it, the less it will hurt...ive mixed my prop with 1 cc of tren and 1 cc of cottonseed oil...i noticed the pain was way tolerable and didn't last as long...the other day i only put 1 cc of tren and 1cc of prop and it definately hurt more without that cc of cottonseed oil...

good luck my fellow proprianators
