I just started using test injections 3 months ago for libido and I cant beleive that I have gained almost a 1/2 inch in the same time , when I have been at stand still length wise for the past 2 years. I had also just got done with a 1 year break back in April and nothing was happening until just recently I measured and almost couldnt beleive it. I thought maybe my wife cut off my ruler or something else was going on. I am doing heavy stretching and long jelq sessions. I dont know if the test has anything to do with it or something else.
