Also, taking Igf-1 gives you mega doses in pulses while HGH gives you a constant elevation of IGF-1, although not nearly as drastic. So they both have their benefits. So for theraputic purposes you'll probably see quicker results from IGF-1 but HGH would be great for maintenance and long term benefits.

igf-1 attaches to myogenic stem cells which are only located in muscle and connective tissues. These myogenic stem cells are responsible for the production of myoblast cells which in turn are responsible for the buildup and repair of connective tissues (ligaments, tendons, cartilage, and joints to a certain extent).

So from this you can see that igf-1 is great for increasing the strength of tendons and also for helping to heal existing injuries while at the same time helping to prevent them.

so in short igf-1 and Deca.
