bro either your gonna suck it up and face the facts and try it, or you'll keep asking about it and fear the pain, everyone is different, one dude may feel like he was kicked by a camel off of winstrol and the next guy feels nothing, the propionate can hurt to varying degrees, you learn to live with it, if it causes pain just go light on the weights, bro in mexico I had a buddy not keep track of the substances filled in the preps and he shot 9cc of ttokkyo testonon in my shouder and arm, and bro if you can live through that then a cc or two of prop isnt gonna kill ya, that case was 10 days of hell on my arm and shoulder, one arm swole up huge and the other arm was shrunk compared to the swole one, cause the dude didnt realize that half of the sostenon was suppose to go on the other side, bro always keep it equal!!!! LIke arnold said, " a mark of a champion is the ability to go through the neverending pain, if you can make it through the pain, that is what separates the champions from the rest of the people"
