I haven't really used arginine
specifically for your purpose. At the time I was experimenting with growth hormone, I noted the thick scabs which formed when I cut myself, and many other things like the growth hormone release which resulted in new hair growth every time.
I have learnt a lot about arginine and poor circulation and heart disease. It produces the most amazing results. However noone believes that these results will endure once you stop supplementation - unless you find the real problem - often caused by lifestyle. For example do you eat bread, biscuits, cakes, pasta too much honey, sugar?
Well here is a challenge for you. Give all those things up and stick to heaps of vegetables, and enough protein for a month. Does that help? Stress is a huge factor contributing to illness.
In any case if you buy the arginine powder, its cheap. It has so many other benefits. Keep taking it...until you sort yourself out.
