Damn, mates. You should have more patients. Start taking it .. it’s different for everybody. Masturbation once in a while(like once in 2-3 weeks) is not crucial but will delay the progress.
By better I mean having firm flaccid penis 25% of the time, it used to be 100%. And when I squeeze my penis now I feel it is spongy and different than it was on the old injured state. I have solid morning erections but they give away in 1-2 minutes if I stand up(still). Since taking arginine the important thing that improved is my libido .. and I feel my penis itching me from the inside to have sex .. and you know that when you feel that the penile circulation is improved(and when it is improved you can expect to heal faster. My record being off of masturbation is 2 months .. then I masturbated once and I went off without masturbation a month .. and so so. You should take much vitamin C .. I noticed improvements in the mood, energy and duration of the effect of L-arginine when I started taking it.
May the force be with you. ^^
