Used it 15 years ago already - back then you could only get a product called Prostin VR. It is very scientific Geek stuff to explain how it works...... but at Pro-level it does amazing things. Personally, I will not use it again - just too ^%$#&@ sore!
Used it on my biceps - couldn't drive my car or blow my nose for a week! Incredible pump, but extremely painful, so much to the extent that it is difficult to train those muscle groups injected with the stuff.
I think site injections with oil-based AAS's on a rotational basis at doses of 1-2mls per muscle group on long term use, will achieve the same results, but with much less pain.
