hello bros... i'm back with a question ,it might help one of my friend who is suffering from tendon injury. Whenever he goes to a doctor,he's getting a clean report of no major injuries, but a minor one (patella tendinitis), so doctors are advising him to take rest and some physiotherapy exercises. But he's completely not recovered from a year. After taking rest for some days,if he does any work which is somewhat stressful to knee,he's getting pain back. Can he take some HGH ..? it is read and heard that it helps to recover from injury..! If he can , what is the dosage and routine he has to follow..?
