thought i share this with you guys on a technique i have been using.i think its the way to go to gauruntee total amount of injection goes and stays IM.theres been time id inject before this and even waiting a few seconds to retract i had seepage of test come out the site,before blood,especialy tren when it hits blood it burns like hell.i have had nothing like that since,the theory is that you push away subcutaneous tissue to the right ,make your injection then release and slid the subcutaneous tissue back over the injection site making a barrier.it also fims up the tissue nice for pinning.
