I'm a 61 year old man.I have used Bodygear 5 different times to improve my tester one levels,with great success. This past winter I went to a lifestyles clinic to have my blood tested. My IGF level was .45. I started using serimolin which did not increase my levels. Purchasing HGH from this clinics was extremely expensive, so I ordered Kalpatropin, (Kalpa) from xroid. I had my blood levels retested and within 10 weeks my levels were over 2.0. I am feeling great,I have nothing but praise for this product. I believe that xroid is a reliable company.
