Not Completely New But Needs Help

To start I am not new been doing manual exercises and stretches since Feb. I started with a bath mate I use in the shower almost each day. I find myself gaining but have slowed. I wanted to go the extender route. I have read good things about a few but from personal experience which do you recommend? I have seen sizegentics and quick extender pro and two I am seriously looking at but open to suggestions about what helped you.

How do I post my own thread it’s kinda hard when it keeps changing to Italian

Can’t help here. Manuals have always brought me the best gains. One day maybe I will also consider an extender and pump. But for now manuals works great.
