I can't figure out why your strength isn't up. you also said you were on a very low calorie diet, but it should still go up some. The fact that there is a lot of PIP is evidence of a lot of testosterone in there. The PIP is from testosterone crystallizing in your muscle, and if it was not saturated with test prop, there would be no PIP. Do yo look better and bigger? I know for 100% fact that is quality prop, get bloods and then once it is maxed out get others opinions. Something isn't quite right. Maybe stop the hcg and the arim for a little bit to see if that helps. I know arim can stifle gains. That and a low calorie diet. Just conjecture at this point.
