Well GHRP6 increases your natural out put of
GH.But this is systematic not site specific
gh.
The article below claims that site specific
gh injections may help the injured area healing process.
Several studies on isolated cartilage and on the joints of rabbits and dogs have shown that cartilage rapidly grows when exposed to growth hormone. Dr. Dunn's research has been designed to illustrate that this effect is due to direct growth hormone stimulation of Glomeruloid formation. In one of his experiments, all cartilage and vascular tissue was scraped from the knees of large, mature adult rabbits, leaving only the bare bone ends. After the surgery, a single dose of growth hormone was injected. In only a matter of days, hundreds of thousands of new Glomeruloids sprang up on the exposed bone surfaces in the joint. Once the Glomeruloids have formed, claims Dr. Dunn, "their only function is to produce cartilage cells." Growth hormone also increases production of collagen, a strong, fibrous connective tissue that attaches cartilage to bone and provides a framework for the matrix. Matrix is the gelatinous, resilient part of cartilage, and its production, too, is increased by growth hormone. Cells called chondrocytes manufacture the matrix. Local administration of growth hormone causes a local increase in insulin-like growth factor I (IGF-I), which sends a message to the chondrocytes to build more matrix. IAGH gives the body the cues it needs to set the cartilage growth process in motion. Stimulation of cartilage regeneration with growth hormone reproduces the same environment in which joint tissues grow during childhood. It is a completely natural therapy.

Another method is somewhat an irritant method, the irritation of the area via injecting various irritant substances instigates the healing process.
