Best way to know what impact it has had would be to get lab work. AAS will effect cholesterol and liver values. A quick blood test will tell you where you're at.
Another option would be to try tren ace next. Its less harsh and can be run for longer periods. You can make better progress if you are using something longer term. So my suggestion would be tren ace at 8 wks on the next run, starting at 50mg EOD and working to 100mg EOD
