Personally, I would think if someone gained that in 2 weeks it would not be permanent gain.. Therefore you would most likely see allot of that fade away over time (unless you continue to do the same routine) But if you managed that sort of gain at all - it suggests you will find your first big gain easy.. I get the feeling from reading things.. You tend to get a good gain fairly quick, then more results slows down (you wait longer for them)
But I am new and I don’t actually know anything.. Only my thoughts
I am glad that it sounds so promising for you
You really are new because those gains don’t happen. .6 inches in 2 weeks, that of a half inch. His dick must have serious stretch mark.
