Of course injects are much more potent than your average testosterone enhancers sold in local stores. however, test injects tend to increase estrogen at an alarming rate and somewhat pause your natural ability to make test. right?? well im wondering will test enhancers/boosters sold in GNC/Vitamin Shoppe will do a good job without pausing your own ability to produce test and without raises estrogen!!! itll be trully suckif i start to grow titties!!! LMAO!!
