Herpes? 
Actually, I had no idea L-Lysine helped treat herpes, probably because I've never had a cold sore or rash other than shingles. Have you used it for this purpose?
Here are some of the benefits of L-Lysine that I know about:
helping the body absorb calcium, iron, and zinc
promoting collagen growth
helping produce enzymes, antibodies, and hormones
supporting the immune system
And specific to bodybuilding and my good health
preventing loss of lean muscle mass and mobility issues in older adults
relieving anxiety
preventing bone loss and osteoporosis by helping the body absorb calcium (I have arthritis and degenerative disk disorder).
promoting the healthy growth of skin
treating shingles
moderating blood pressure (My blood pressure is on the high side of normal 118/70 average)
preventing plaque buildup in arteries
supporting hair growth
building muscle in bodybuilders
helping athletes recover from intense workouts
