Very very good, had great results... 1ml/day for 8 weeks, only once or twice had some serious pain... Everyone is on the band wagon of Prop hurting or diluting it with EQ or something...Suck it up, you know what it feels like to inject 6000mg of test a week no counting all the other shit Pro's take in a weeks time...Imagine there pain...
Although I know there are some types of Prop that do hurt like a bitch like Loeffler prop 250 or other stuff like Denkalls T-400, crippling...100mg prop aint shit
