I made 250mg/ml of Prop and as far as pain goes its no different than any kind of soreness that I get the day after anything of any kind with any ester. Just a little sore. I massage it real good after and the soreness is gone in a couple days. Good enough time to inject EOD. I used 100% EO for my oil and it flies right through a 25g pin better than any other oil I've used through a 23g. Heres the recipe. Makes about 80ml
43 mls EO oil
20 grams Prop powder
2ml BA
20ml BB
