hGH can have healing properties. Some of it also comes from the IGF-1 released from the liver when it's stimulated by GH. However, this should only be used in your 20's because your pituitary still hasn't reached it's peak until then, after which it begins declining. It's a dangerous game to play with hormonals before you're mature enough.
Fishoil can help joints heal, particularly the EPA. Try to get as much of that in your system.
You can also use a topical cream to help increase blood flow and immune response to specific areas to help increase healing. I'm going to try AgeForce's Muscle Recovery Gel since I got it free in one of their promos, I've got a bum shoulder that could use some help.
