i just realized that i didn fully answer your question bro sorry. hehe yeah it is late. prop has been used for site injections with mixed feelings. i don't really like the idea personally because it's a test with an ester attached to it. steroids wth no esters attached are better for site injections. now some people can argue though that with prop growth occurs as well and probably for goodreason. the reason being the more frequent shots most likely in the lagging bodypart might cause fascia stretching from the oil buildup which may lean t more muscle growth. try it and see, im not a big believer in it like i said, but i know people that swear by this for site injections
