I was reading the injecting steroids article on steroid.com and it said to draw out the liquid, I need to first draw some air into the syringe?? wouldnt drawing air into the syringe and then putting air into my body kill me???... also, I heard that using an AI is better than Nolvadex if you see signs of gyno... which AI and do regular stores carry this item?? do any stores carry nolvadex or will this be an item I have to hunt down??
