Just wanted to let everybody know: I started 5 weeks ago with the Length Master, 5 days a week around 50 minutes per day, length routine like in the SRT. It's really intense and I gained 0.4cm (little less than 0.2") in 5 weeks. I'm now BP 19,6cm (7.71").
I'm really happy as my length seemed to have stalled for months when I did a combination of mostly stretching by hand and once a week with the length master.
If I can keep this up I will almost reach my desired length of 21cm (8,26") by the end of the year!
Thanks to this blog and thanks for all you guys!
