There are 2 methods of injecting HA in the glans - deep or superficial.
Deep - into the actual erectile tissue. Unfortunately the blood flow just washes it away. Have given that up.
Superficial - into the skin of the glans. What is done in Korea for premature ejaculation. Definitely can give long term enlargement but may be lumpy/visible. Is used to reduce sensation - great if that is what you want.
What we do for long term size enhancement - inject Aquamid. Aquamid is Polyacrylamide gel. I will post some links later. Going to be doing a study this year on it. Looking good so far.

Glans Augmentation makes minimal difference to the length, maybe a couple of mm. It is more for width/flare.
Aquamid has been around fro 21years in Australia. It has a remarkably good long term track record. It was started by a Urologist for patients who were having pump implants for impotence. The implant sorted the shaft but left a soft glans so they started injecting Aquamid.
