I’ve gained over a inch in 1,200 hr put in. I believe the reason most isn’t gaining is because most don’t put enough hours in, in a day. 3/4 hours a day that most put in is not enough hours. Even the company’s will tell you this. but it seems most think as long as they put in 4hrs a day and still hit there 1,500hr mark that is all that matters. Well it isnt! You need to put in at the least 6hrs or more a day! It should be 8hrs or more a day! I believe this is why most don’t get any results. And how is everyone claiming flaccid gains but no erect gains is beyond me also.. I’ve made great solid gains using my stretcher and know plenty others as well. And to the ones claiming they use a stretcher and us the of, I wouldn’t count that as a stretcher..
