First I know this is absolutely backwards and won't do this again. Started first cycle with test -c ran 500mg for 5 weeks. Notice semen was clear to almost non- exsistent. As I expected with being shut down. So I switched to prop (so I didn't get bloated because it is summer and I wasn't sure what to expect.) and have been running prop at 150mg EOD for last three weeks. Well balls are back to normal size, swimmers are back. So i'm wondering if my test-prop is bunk. I saw good gains 4th-5th week along with strength increase. THe past three weeks I haven't gained nor really increased strength. I had sides by week 3 oily skin, a bit of acne (which I never have) and now week 8 nothing skin is clear. I think I know the answer but thought i'd throw it out there. My test-c and test p were from different sources. Thanks brothers any input or info is much appreciated.
